Fungicides

EPA Opens Public Comment Period On Draft Fungicide Strategy

Mon, 04 May 2026 16:20:14 GMT

The U.S. Environmental Protection Agency (EPA) is offering the U.S. public an opportunity to help shape the future of agricultural safety, unveiling a draft Fungicide Strategy designed to balance the needs of American farmers with the protection of the nation’s most vulnerable wildlife.

The proposal marks a significant step in the agency’s effort to meet its dual mandates under the Endangered Species Act (ESA) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). By creating a more efficient and transparent framework for pesticide registration, the EPA says it aims to “safeguard more than 1,000 federally endangered and threatened species” while ensuring growers maintain the tools necessary to protect the nation’s food supply.

A New Framework for Modern Farming

The draft strategy focuses on conventional agricultural fungicides across the lower 48 states — an area covering approximately 41 million treated acres annually. Rather than a one-size-fits-all mandate, the proposal introduces a three-step framework:

Identify Impacts: Assessing potential population-level effects on listed species.
Mitigation Planning: Pinpointing specific measures to reduce those risks.
Targeted Application: Determining exactly where these protections are most needed based on where endangered and threatened species live and how fungicides move through the environment.

The agency emphasizes that while this strategy guides future regulatory actions, it does not impose immediate requirements. Instead, the strategy serves as a roadmap for upcoming registration reviews, with the EPA promising public input on every specific action before it is finalized.

Balancing Innovation and Conservation

Saying that it recognizes farmers are the backbone of the U.S. economy, the EPA’s draft includes several updates to provide greater flexibility. Notably, the plan expands options for reducing spray drift buffer distances and introduces new mitigation tools, such as the use of “guar gum” as a spray adjuvant.

"[American farmers] need a diverse toolbox of innovative agricultural technologies to manage crop disease, prevent resistance, and produce the affordable, nutritious food that feeds our country,” the EPA says, in a press release. “The draft Fungicide Strategy is designed to ensure those innovative tools remain available and that they are used in ways that protect the environment and endangered species.

How to Get Involved

In a push for transparency, the EPA has opened a 60-day public comment period to gather feedback from scientists, conservationists, Tribal partners and the agricultural community.

Public Comment: Stakeholders can review the strategy and submit formal feedback via (Docket: EPA-HQ-OPP-2026-2973) through June 29, 2026.
Informational Webinar: The agency will host a public webinar on May 20, 2026, at 2 p.m. ET to walk through the proposal and answer questions. Register here .

The EPA expects to review all public input and finalize the Fungicide Strategy by November 2026.

Farmers Emphasize Demand, Not Payments, Is The ‘Bridge To Better Times' For Agriculture

Wed, 22 Apr 2026 22:26:14 GMT

Two Midwest farmers are pinning their hopes for the future on stronger demand for corn and soybeans — especially the latter — as they navigate tight margins, high input costs, and an uncertain price outlook.

Northern Illinois farmer Steve Pitstick and south-central Iowa farmer Dennis Bogaards say they have exhausted most cost-cutting options for this season. They believe future profitability now rests on whether demand for both crops — particularly from domestic soybean crush and fuel markets — expands enough to support higher prices.

One silver lining currently, Pitstick says, is his relatively strong position on fertilizer heading into the 2026 planting season.

“We will do pretty much the dry spread program we always do,” he says. “We cut the rates a little bit on the phosphates just because of price. We booked our 32% in September, something we traditionally do. We have all the nitrogen bought, so I feel good about 2026 from that aspect.”

While he believes additional fertilizer is available, he notes it will likely be priced at a premium.

“I believe I can get more if I need it. I may not like the price, but I can get more,” he told AgriTalk Host Chip Flory during the weekly Farmer Forum segment.

Little To No Expansion On The Horizon

As the season begins, both farmers emphasize that the coming years will have farmers focusing on survival and strategic adjustments rather than acreage expansion.

One adjustment Bogaards is making is front-loading some of his nitrogen needs this season while leaving a portion open in case prices break.

“We booked anhydrous early on for this year, back in early fall, and got an OK price,” Bogaards says. “I have a little bit of sidedress that we do. We book about half of that, and I sit open on the rest of it. I’ll wait and see where it goes.”

Bogaards remains committed to sidedressing as long as product is available and prices do not continue ratcheting up. “If I can get it, I’ll put it on, unless it is a crazy, crazy price,” he says.

Like many U.S. growers, both Bogaards and Pitstick say there is virtually no room left to cut fertilizer use without risking yields.

“There is no place to cut back. We are being as efficient as we can be,” Pitstick says.

Bogaards agrees, noting that nitrogen is not the place to skimp. “Maybe a year or so, you can cut back on the P and K a little bit, but you do not want to get caught in three or four years of that.”

He also remains reluctant to drop fungicides. “Fungicides really pay off,” he says. “In the past, we did not use them, but the last few years they really paid, and I would hate to not spray them.”

Uncertainty About The 2027 Crop Mix

While the 2026 crop is largely “business as usual,” both farmers told Flory that 2027 brings real uncertainty—especially regarding nitrogen supplies. Pitstick is concerned about how global demand could impact costs for U.S. producers.

“I am worried about the price of the nitrogen,” he says. “It may not be an issue in the United States from a supply standpoint, but the rest of the world… could export our product because of opportunity cost, and that drives the price up. It is a total wait and see.”

Flory underscored how global trade flows directly shape what American farmers pay, noting that some fertilizer shipments originally destined for the U.S. were recently rerouted.

“Some boats are diverted from the U.S. to other countries,” Flory says. “If you want your share, you have to beat the next guy in line with the price.”

If nitrogen prices soar while corn prices stagnate, Pitstick says his rotation could shift. “That might change how we do things in 2027. We may have to go to more soybeans,” he says.

Bogaards also expects to alter his corn–soybean mix, given the potential demand from domestic crush and renewable fuels.

“In the past, we were probably 60% to 65% corn,” he says. “We have been backing off of that. I still do a little bit of corn-on-corn, but I might try to go to a 50–50 rotation.”

Flory believes this shift could help rebalance supplies and improve price prospects. “If we can pull some acres away from corn and get this thing rebalanced, maybe that is our bridge to a better time,” Flory says. “Our bridge to a better time is more demand across the board and crops competing for acres — not another payment.”

Bogaards says the shifting economics are already evident. “A couple of years ago, people said soybeans are a drag on our financial statements. It looks like almost the opposite right now.”

Even so, Bogaards is cautious about making long-term decisions based on short-term signals. “I can change acres right now, but by next fall, it might be the worst decision. I think you have to go with your rotation and stick with it.”

Pitstick links his long-term outlook to fuel sector growth, noting that both corn and soybeans increasingly function as energy crops.

“Some of the most profitable years of my career were when we had high fuel prices because we were also a fuel crop,” he says. “I have some optimism that these high fuel prices will cause some demand and increase our crop prices.”

For now, both farmers say their immediate job is to manage through 2026 while keeping their options open. With high costs for fertilizer, fuel, and machinery, they see expanded demand as the only realistic path forward.

“It is just survival at this point,” Bogaards says. “We just have to make sure we can survive and keep plugging through it.”

Defend Every Bushel With A Proactive Disease Plan

Wed, 08 Apr 2026 17:36:22 GMT

Addressing corn disease pressure in-season is rarely a matter of “if” and more likely “when.” Coming off heavy disease pressure from 2025, now is the time to put your plan together for how you’ll address challenges like northern corn leaf blight, tar spot and others this season. Plan your moves with these five recommendations, so you are ready to take action when disease pressure hits:

1. Use A Proactive Scouting Plan.

Success begins with staying ahead of disease, according to high-yield corn grower David Hula. “You have to stay proactive with your scouting and willing to go with earlier fungicide or even multiple applications, depending on what shows up,” he says.

While planning, consider the following:

1. Know your potential threats. Depending on the disease, some pathogens survive the winter on previously infected crop residue (e.g., northern corn leaf blight, tar spot). Other diseases move into northern growing areas on winds from southern locations (e.g., southern corn rust). For a suitable environment, many foliar diseases need warm, humid, and wet conditions to propagate.

2. Have your budget in place. Be ready for at least one in-season fungicide application. Use tools like the Newly Designed Fungicide ROI Calculators to guide your investment in products and applications. By inputting costs, market prices, and disease severity, these calculators provide research-based estimates of net benefits and breakeven probabilities, helping you make a more informed decision.

3. Delegate the scouting job, if necessary. If you cannot scout personally, assign the task to a family member, employee, or employ a professional service.

“Lots of great pest managers work in retail,” says Ken Ferrie, Farm Journal Field Agronomist. “Their success depends on you being successful also.”

2. Leverage Friends, Neighbors And Industry Expertise.

Don’t monitor disease pressure in a vacuum. Stay informed about what’s moving into your neighbors’ fields; track regional pressure by tapping into local agronomists and organizations like the Crop Protection Network.

Randy Dowdy, Hula’s partner in Total Acre, notes that in the Southeast, farmers are constantly receiving feedback from Extension and industry experts regarding southern rust.

Similarly, Elliott Henderson, who farms in Buchanan County, Iowa, has a group of farmers there that he connects with on a regular basis during the growing season.

“It’s a network of dozens of us farmers that call each other, bounce ideas off each other,” he says. “The things we’re talking about are often time-sensitive. It can be a daily thing.”

3. Select The Right Chemistry.

Applying the wrong product in the heat of battle with disease pressure is a common mistake. For aggressive diseases like tar spot or southern rust, Farm Journal Field Agronomist Missy Bauer recommends using “Cadillac” type chemistries — newer technologies that feature multiple modes of action.

To ensure you are using the right tool:

Consult Your Experts. Use the Crop Protection Network’s Fungicide Efficacy tables to see which products perform best against specific diseases.
Match Product to Problem. Ensure the product is labeled for your specific issue and is capable of handling high-pressure scenarios.

4. Optimize Applications for Maximum ROI.

If you need to apply a fungicide, make sure it delivers the results you need.

“It’s all about coverage,” Dowdy says. “Drone applications can be fine, but no matter what you do, if a guy is spraying two to three gallons, and you compare it to a ground rig spraying 15 to 25 gallons, I mean, there’s just no comparison in that coverage.”

Another aspect of coverage, Hula adds, is making sure the fungicide gets into the plant canopy far enough to have the desired effect. That becomes even more critical as the season advances.

“Fungicides have a tendency to work from the leaf they’ve come in contact with and move up,” Hula says. “So, if you’re trying to protect at least that ear leaf – and I like to protect the leaf opposite and below the ear – you’ve got to get penetration with that product.”

Hula says growers might have to spend a couple extra dollars to get sufficient volume for the product to get down below the canopy, if using a drone for application.

“If that’s what needs to be done, let’s do it,” he encourages. “If I’m spending $30 or more an acre, then I want to at least have the success that I’m paying for.”

5. Commit To Protecting Corn Through The Entire Season.

Modern corn genetics have significant “back-end” potential, enabling them to add yield through kernel fill late into the season. Hula and Dowdy advise against walking away from the crop early. They say evaluating fungicide applications during later reproductive stages can often yield a high return on investment.

D hybrids are of particular concern late-season, Ferrie says. These are hybrids that have kernel depth changes, positive or negative, based on populations and environmental conditions during the last 30 days of grain fill.

Missy Bauer, Farm Journal Field Agronomist in Michigan, zeros in on corn growth stage to guide uber-late-season fungicide applications.

“If I had a field that has no fungicide at all on it, and I had fairly heavy disease pressure from something like southern rust or tar spot, and I’m at early R4, I would still apply the fungicide,” she recommends.

Early Soybeans Benefit From Protection In Cold Soils

Tue, 24 Mar 2026 20:11:52 GMT

When the calendar says it’s still a little early for soybeans but field conditions are just right, growers face this increasingly common dilemma: plant and risk the outcome in cold, tough soils—or wait and risk missing the best window.

More farmers are deciding to go early. As they do, seed treatments and inoculants are playing a bigger role in helping growers manage the risks, reports Missy Bauer, Farm Journal Field Agronomist, based in south-central Michigan.

The Case For Inoculant Use

While soybeans naturally fix nitrogen through root nodules, the process depends on the presence of Bradyrhizobium bacteria. Inoculants introduce these essential microbes to maximize nitrogen fixation and crop performance.

Inoculants are most often useful, the Crop Protection Network (CPN) reports, when fields have no history of soybean production, or when the field has gone four or more years without being planted to soybeans.

Farm Journal Field Agronomist Missy Bauer says her field research in south-central Michigan indicates inoculant use can also be a net positive in “ultra early” soybean planting. She has spent the past three years evaluating Preside Ultra, a “super-concentrated” soybean inoculant.

“The results are pretty positive,” says Bauer. “We’ve seen good early growth all three years that we looked at this product.”

Three years of field testing show a solid return-on-investment for the inoculant.

(B&M Crop Consulting, Coldwater, Michigan)

Her data shows the product has added about 2.4 bushels per acre on average, delivering roughly $25 per acre in return for about $1.10 per acre more cost than a “standard” inoculant.

“I’ve been pretty happy with what we’ve seen with the enhanced early growth,” Bauer says. “I think the product pairs well with when I plant early, what we can do to get these beans going better knowing that they’re in a tough, cold environment.”

Seed Treatments Continue To Play A Valuable Role

When it comes to protecting early-planted soybeans, Bauer says seed treatments like Ilevo and Saltro still earn a place in growers’ plans as important production tools.

“While we aren’t continuing to research the Ilevo, we have that good history of Ilevo seed treatment and still recommend growers use it or Saltro,” she says.

For Bauer, that “good history” matters. Even without continuous new trials every season, a solid base of multi-year data gives her confidence to keep recommending both products, particularly when growers want to push soybeans into colder soils ahead of the traditional planting window.

Her message to farmers is that early planting doesn’t have to mean planting unprotected. With a strong track record and comparable performance in her trials, she views Ilevo and Saltro as dependable options when the goal is to capture the yield upside of early soybeans while managing the risk that cold, challenging environments can bring.

While Farm Journal Field Agronomist Missy Bauer says she is not conducting further testing on Ilevo or Saltro, she has confidence in their performance in soybeans, especially in early-planted crops.

(B&M Crop Consulting, Coldwater, Michigan)

The CPN says the benefit of a seed treatment is most evident when reduced soybean seeding rates (140,000 seeds per acre or less) are used. In many regions, the minimum plant stand for highly productive soils is 100,000 plants per acre. Because farmers want to minimize input costs while maximizing yield, they may reduce their seeding rates and use seed treatments to help protect the stand, CPN reports.

Next Steps For Your System

For most soybean growers, adopting a different inoculant or seed treatment won’t require a major overhaul. In many cases, it’s a conversation with a seed dealer or custom treater, Bauer says.

Four next steps she recommends:

Talk to your seed dealer about the inoculant and seed treatment options they offer and the potential benefits.
Review local data from plots in your area, especially where beans were planted early.
Match products to your planting plans — early planting into cold soils typically justifies a more robust treatment package.
Consider a strip trial for evaluation purposes. Compare your standard package against an upgraded inoculant or seed treatment.

For farmers looking to protect their early-planted soybeans — and squeeze a few more bushels out of every acre — upgrading the inoculant and revisiting their seed treatment package may be one of the simpler, higher-return changes they can make, Bauer says.

Are You Planting Second-Year Soybeans And Skipping Corn?

Fri, 20 Mar 2026 20:26:56 GMT

As input prices and markets fluctuate, many U.S. farmers are considering a shift from corn to soybeans this season. For some, like northwest Missouri farmer Todd Gibson, continuous soybeans aren’t just a one-year pivot—they are a long-term strategy to capture ROI on challenging soils.

Gibson, based near Norborne — a farming community that proudly bills itself as the “Soybean Capital of the World” — keeps a traditional corn-soybean rotation on his Missouri River bottom ground. But most of his fields with tougher, gumbo-type soils haven’t seen a corn planter in two decades.

“Growing corn on some of this heavy ground just doesn’t pay,” Gibson explains. “I’ve got some fields that have been in continuous soybeans for 20-plus years now.”

More Second-Year Soybeans In U.S. Farmers’ Plans

Gibson says he will grow more soybeans this season and on his better ground. “I’m going to cut my corn acres maybe in half. I’ll have more beans on the better dirt this year, mainly because of input prices,” he says.

Other U.S. farmers – many without Gibson’s experience – are looking to grow second-year soybeans. The Allendale Report released March 18 says private acreage estimates point to a shift toward more soybeans this season, notes Rich Nelson, chief analyst. He estimates U.S. corn planted area at 93.678 million acres, down about 5.1 million acres from 2025, while soybean acres are pegged at 85.659 million acres, up roughly 4.4 million acres over last year.

In southern Illinois, farmer and broker Sherman Newlin says the conversations he has with farmers these days are dominated by input costs and fertilizer availability concerns. While some tell him they’re sticking to their corn-bean rotations, others are considering a 100% shift to soybeans. Newlin is keeping his options open.

“I’m not planning on switching, but we’ll see,” he says. “We’ve still got a few weeks to go where we can swap out seed if we need to.”

Iowa Soybean Association Agronomist Lucas DeBruin says the farmers he works with in the state are sticking with their regular rotation and planting corn if that’s what the original plan was for this season.

“We use a lot of fall anhydrous here, so most guys are pretty locked into growing corn,” DeBruin says. “A lot of them also need the corn for livestock feed. Sometimes you can still squeeze a little bit more margin out of corn than the soybeans,” he adds, “and guys like growing corn more than soybeans. It’s more fun to pick corn.”

Look Before You Leap: The Ferrie Checklist

For farmers looking to change their seed order, Farm Journal Field Agronomist Ken Ferrie suggests taking a hard look at your balance sheet and your fields first. Here are some of his key recommendations:

Consider What You’ve Invested To Date: If you’ve already applied fall anhydrous or dry fertilizer for a corn crop, the “switch to beans” math doesn’t work. “You can’t afford to go to beans, because you’ve already spent the money,” Ferrie contends.

Account for the Yield Penalty: In a beans-after-beans scenario, Ferrie tells growers to expect a 5-to-7-bushel yield drag due to more stress from potential disease, insect and weed pressure. His question: “If you take 7 bushels off your bean yield, does it still cash flow against your corn APH?”

The Management “Claw Back": You can potentially mitigate some of the yield penalty in second-year soybeans by moving your planting date up from May to April, Ferrie says. Early planting helps the crop get an earlier and longer flowering period which can help recover some of the lost potential.

One morning this past week, Ferrie noted that the market was leaning back toward corn and that the see-saw between crops could continue this spring — another factor to keep in mind.

“Looking at the markets this morning, I think a lot of guys would prefer growing corn at $4.90 than beans at $11.10,” he contends.

The Continuous Soybean Playbook

For Gibson, success with continuous soybeans works based on a disciplined management system he relies on every year:

Fertility is Foundational. Even if you shift from corn to soybeans, Gibson says be aware that the beans could require more nutrients. He monitors his soil fertility closely, noting that continuous beans often require extra sulfur, phosphorus and potassium. He also keeps a close eye on micronutrients to ensure the crop won’t hit a hidden yield ceiling.

Non-Negotiable Seed Treatments: In continuous soybeans, the soil is more likely to become a reservoir for pathogens. Gibson hasn’t put a bare seed in the ground in 20 years. “Seed treatment guarantees me 100% replant,” he says. “It lets you sleep better at night knowing that if you get a heavy rain, you have that insurance to fall back on.”

Row Spacing and Canopy: Gibson plants in 15-inch rows at a rate of roughly 130,000 seeds per acre. The goals are quick emergence and a quick canopy. He believes a fast-closing row is your best defense against weeds and helps preserve soil moisture in the heavy gumbo. Seed treatment use and regular scouting help him feel confident in using narrow rows.

Keep Your Boots In The Field: In a corn-bean rotation, the “break” in the cycle helps farmers manage various diseases, insects and weeds. In continuous soybeans, you lose that advantage.

Gibson compensates by routine scouting and being prepared to address problems. “If you hear your neighbors have bug pressure, assume you will, too,” he says. “Don’t have the attitude that you can ‘get by,’ because you probably won’t.”

He has similar thoughts regarding weed pressure – “be proactive.” His program typically starts with a pre-emergence/burndown or early post application, with residual herbicides used to hold back weeds. If weeds break through, he is prepared to return with a post pass.

“We kind of wish sometimes we didn’t have to worry about weeds so much,” he says. “But if you don’t, then next thing you know, you think, ‘Oh, I wish we would have sprayed.’”

The Genetic Advantage: The final piece of the puzzle for Gibson is the advancement in soybean technology. He recalls the days when he says Williams 82 was his only real option for continuous soybeans. Today, advanced traits have made managing weeds and disease in continuous systems much more manageable, he notes.

On his continuous soybean acres, Gibson consistently sees yields average in the 50-to-60-bushel range. When he factors in the lower input costs compared to growing corn on heavy gumbo ground, he believes the decision to go with continuous soybeans is a good one. For Gibson, it’s not about following a trend— it’s about knowing what his land does best and having the management practices in place to succeed.

FBN Report: Tariffs Drive "Fragile Stabilization" in 2026 Crop Protection Market

Fri, 06 Mar 2026 19:52:48 GMT

The crop protection market—from a pricing standpoint—has shifted from a time of extreme volatility of recent years to what’s characterized by fragile stabilization. That’s one takeaway from FBN 2026 USA Ag Chem Price Transparency Report, which also notes how tariffs have driven the floor of prices higher.

The Impact of Tariffs on 2026 Inputs

Farmers should prepare for a 4% to 6% increase in overall chemical budgets. While the wild price swings of the post-pandemic era have settled, secondary costs like labor, fuel, transportation and tariffs are pushing retail prices upward.

“As the tariffs were implemented throughout 2025, the effects were felt in different ways in different times,” says John Appel, VP of Category Management at FBN. “A big reason for that was that product inventory had to be driven down in the channel before it was felt very broadly. And I think we did see that going into 2026 now, prices are definitely up versus the same time period in 2025, and that’s largely because tariffs have become structurally part of the cost for the farmer at this point.”

Trade duties and anti-dumping penalties—particularly on imports from China and India—are the primary drivers of price spikes for 2026. Key active ingredients (AIs) most affected include 2,4-D, S-Metolachlor, Clethodim, Dicamba, and Glufosinate.

Details on The Data Sources

FBN sources its data for this report on ag chemical invoices submitted by farmers, and this year’s report included 1,372 prices from 122 insecticides, fungicides, herbicides, and adjuvants purchased June 1, 2025, and January 18, 2026 across 31 states. Participants are often incentivized with Amazon gift cards. Fifteen crop protection products had price variances of at least 25% from the lowest price to the highest price.

“Really the value is in the data. It depends on the year and the amount of participation we get, but we try to get a big enough pool where we can make a robust analysis,” Appel says. “The spread being a little bit tighter in 2026 was due to the tariff volatility. In 2025, you had at some points in the year pre-tariff prices that were being invoiced, at some points in the year post-tariff prices that were being invoiced, and so you see a very large spread in that case. And we don’t have that to the same extent this year as that.”

This is about 1,000 invoices lower than the 2024 data that was based on 2,400 invoices from 33 states. The company has done its price report for almost 10 years.

“FBN was founded based on a Moneyball approach. Crop protection prices information was really asymmetric, and so price transparency was launched in 2017 as a way to even the playing field, so to speak. We capture that data, and we anonymize it, and aggregate it, and analyze it at a top-line level. And so that allows us to share back with our farmer members what’s happening on a product-by-product basis in the market and really arm them with the knowledge they need to make informed decisions,” Appel says.

Price Variability

The report advises moving away from “just-in-time” purchasing. Instead, it suggests buying in the fall to hedge against mid-season tariff changes and logistical bottlenecks in global shipping, which are projected to be a bigger risk in 2026 than manufacturing capacity.

“As the procurement window gets tight with overseas suppliers, with global markets, this is the time that that’s really felt, and we know that prices move about 10 points on average from pre-season to in-season, so that’s quite a bit. Now, will it be 10 points on every product all the time? Probably not, but in general, buying in the fall, buying early, even now, pre-season, where you can, makes a lot of sense,” Appel says.

On a national scale:

Clethodim 2E showed the highest variability with a 144% difference between the lowest and highest prices ($28.85 vs. $70.49).
Generic glufosinate followed with a 130% spread.

The FBN report shows persistent price variability, and farmers in neighboring states can pay a 50% price difference on the same products.

Generics vs. Branded: Where to Save

From the report, there is a push toward generic alternatives. For example, the report claims farmers could save 30% by switching to generic 2,4-D options or 11% on glyphosate compared to branded Roundup PowerMAX 3.

This data may not fully capture the complex “net-net” pricing traditional retailers offer through bundled seed-and-chemical rebate programs, which can significantly lower the effective cost for farmers who stay within a single manufacturer’s ecosystem.

When Weird Corn Ears Wreck the Bottom Line

Mon, 02 Mar 2026 15:20:06 GMT

Abnormal corn ears may look like a cosmetic problem, but depending on the severity, they can deliver a significant hit to yield, reports Osler Ortez, Ohio State University corn specialist.

“If a field is managed for 200-bushel corn but only delivers 100 bushels because abnormal ears dominate, then every pound of nitrogen, every inch of irrigation and every pass you make across that field becomes much harder to justify,” he says.

Yield losses from abnormal corn ears can range from 35% to 91% in affected plants, with typical field-wide impacts often trailing lower, Ortez reports.

For reference, an “average” corn ear generally produces 16 kernel rows with about 800 kernels per ear, according to the Iowa State Extension.

Irregularities such as zipper ears (shown below), earless plants or multiple ears, reduce grain yield through poor kernel set, abortion or reduced kernel weight.

A common abnormality called zipper ear is caused by kernel abortion or failed pollination. The issue is often triggered by severe environmental stress during early grain fill or pollination from factors including drought, high heat or nutrient deficiency.

(R. L. Nielsen, professor emeritus and Purdue University Corn Specialist, retired)

Ortez emphasizes no single factor explains abnormal ear development. It’s nearly always the result of an interaction between three factors that corn researchers refer to as GEM:
G — Genetics (hybrid)

E — Environment (weather, stress)

M — Management (practices)

He adds that understanding when the stress is happening, the timing of it, is also important. For instance, early-season stress can limit ear initiation and potential ear number, while midseason issues impact pollination and kernel set. Late-season stress reduces kernel fill and overall weight.

Strategic Management Levers

While the weather can’t be controlled, Ortez says understanding the GEM interaction gives corn growers more leverage than they realize.

He lists three management decisions that can help growers mitigate the risk of abnormal ear development:

1. Evaluate the genetics: Treating hybrid selection as a defensive tool against ear problems — right alongside disease tolerance and standability — is one of the clearest ways to lower risk.

2. Pick a recommended seeding rate: In Nebraska field trials, Ortez observed abnormal ears increased at both ends of the seeding rate spectrum.

“Chasing a few extra bushels with aggressive populations, especially on drought-prone or otherwise stressed acres, often backfired when stress hit at the wrong time,” he notes. Conversely, pulling populations too low also created conditions where ear development went off track.

3. Consider the planting date: Researchers found planting hybrids outside the optimal window — either very early into cold, wet conditions or very late into heat and moisture stress — made it more likely sensitive growth stages would line up with damaging stress. Matching planting date to local recommendations and the strengths of a given hybrid proved to be an important way to reduce those risky overlaps.

Ultimately, by tuning into GEM, farmers can better safeguard their investments. As Ortez points out, the more sides of that triangle a farmer can stabilize or improve, the less likely a season’s worth of hard work and inputs will be undone by a field of problem ears.

Hear Ortez share more of his research on abnormal ear development in a recent podcast sponsored by the Crop Protection Network.

Put More Spray Where It Pays

Thu, 29 Jan 2026 17:01:56 GMT

When you pull the sprayer into fields each spring, you’re banking that the product coming out of the nozzles will land where you need it to work. That’s where drift reduction adjuvants (DRAs) can become one of the most profitable—and protective—ingredients in your tank.

Consider what happens when you spray a crop protection product. Each nozzle throws out a spectrum of droplet sizes, from big “marbles” that fall quickly to tiny “dust” droplets that hang in the air, explained Greg Dahl, director of adjuvant education for the Council of Producers & Distributors of Agrotechnology (CPDA), during a recent Agricultural Retailers Association webinar.

Those tiny droplets, called driftable fines, are the troublemakers. They lose energy fast, ride the wind and can move well beyond your field. That’s not the case for larger droplets.

“Big droplets have to land. They are going to land, and they’re going to land close to where you spray,” Dahl says. “Small droplets, they probably are not going to land. They will lose their speed, and then they’ll just float in the air and go wherever the air goes.”

By design, DRAs shift more of your spray volume into larger, heavier droplets that are still effective but far less likely to drift. Across a wide range of nozzles, Dahl says industry research shows that adding a DRA can reduce the spray volume made up of driftable fines.

“Going across the whole system of nozzles, we get about a 50% reduction in the amount of spray volume that is made up of driftable fines,” he reports.

In practical terms, that means less product left hanging in the air and able to drift toward your neighbor’s crops, garden or yard.

There are at least four benefits to adding a good quality DRA in the tank.

Drift Control Is Only Part Of The Benefit From DRAs

Many farmers are concerned that bigger droplets going out of the nozzles will automatically result in poorer coverage, particularly in post-emergence applications. In some cases — especially with ultra-coarse sprays — that’s true, Dahl says. Coverage can suffer, and penetration into the crop canopy can be weak. The right DRA, though, has been shown to increase droplets’ speed as they leave the nozzle, which improves penetration into the crop canopy.

“If we look where we have added in a DRA, it has actually increased the amount of speed of those droplets, so they’re going to go farther before they run out of energy, and we’re going to get better penetration of the canopy, better deposition farther down,” Dahl says.

Side-by-side comparisons in corn and soybeans using fluorescent dye tell the story more completely (see below). Without a DRA, Dahl’s slides illustrate that coverage is good on the top leaves of the crop but falls off quickly as the product moves down into the plant. With a deposition-type DRA, coverage is more balanced from the top to below the ear leaf in corn and throughout the soybean canopy.

A good quality DRA helps provide good product coverage all the way through the crop canopy, as noted in the plant on the right.

The ROI Of Improved Product Applications

Better coverage does show up in yield results, Dahl reports. Across hundreds of corn fungicide trials, for instance, he says adding a DRA to the tank delivered an average yield increase of about 5.7 bushels per acre compared to fungicide use alone.

In wheat, similar work showed nearly a 4‑bu.-per-acre advantage.

There’s also an economic advantage in terms of product retention. When you reduce the number of driftable fines, more of the active ingredient you paid for actually lands and stays in your field instead of drifting away.

Dahl says not all DRAs and nozzle combinations are created equal. Some thicker, polymer-type products can narrow the spray angle or even increase driftable fines with the wrong nozzle used, especially Venturi designs. That’s why choosing proven products matters. He says oil-emulsion DRAs, in particular, have shown they can cut driftable fines without creating an overly thick spray or sacrificing pattern quality.

“There’s almost 500 labels that recommend using CPDA-certified adjuvants, and there’s over 200 products that are CPDA-certified adjuvants,” Dahl says, referencing the website CPDA.com . “We think that’s where you should go for information, and we thank you for that,” he adds.

Unmask the 'Party' in Your Corn Crop

Thu, 15 Jan 2026 20:06:14 GMT

For years, crown rot was viewed through a narrow lens—a single pathogen causing a single problem. But researchers at the University of Nebraska and Iowa State University suggest the reality is much rowdier. They report that crown rot often behaves like a disease complex rather than a solo act.

According to Alison Robertson, Iowa State University Extension field crops pathologist, the disease is frequently the result of a “party” of organisms. Robertson and Tamara Jackson-Ziems, University of Nebraska field crops pathologist, have often found a crowd of fungi – including Fusarium graminearum, the organism Phytopythium ambiguum (nicknamed “Pam”) and others – within the same rotted crown.

“One of the big unanswered questions is which ones start the infection, which ones join later, and which ones are just saprophytes feeding on dead tissue,” Robertson says.

Jackson-Ziems adds that she and Robertson are exploring the possibility that these pathogens must work together to produce the severe symptoms growers frequently see in their fields. While this complexity makes the disease harder to address, the researchers offer five practical steps you can take to prevent or minimize the impact of crown rot this season..

1. Evaluate Corn Hybrid Disease Ratings

While few if any hybrids are currently scored specifically for crown rot, field work in Nebraska shows clear differences in how various genetics handle the disease. Jackson-Ziems advises looking beyond general disease ratings.

“Talk with your seed dealer about data on hybrids specific to crown rot or early plant health,” she suggests.

Matt Essick, Pioneer agronomy innovation leader, notes that other traits are your best defense. Trait scores such as stress tolerance, stalk strength and stay-green can help combat symptoms, he explains.

2. Manage Early-Season Stress

Crown rot is heavily linked to “wet feet” and cold starts. While it is difficult to replicate the disease in a lab, Robertson notes practical experience shows that planting into cold, saturated soils—especially in fields with a history of the disease—is an invitation for trouble.

Brett Leahr, a regional agronomist with AgriGold, points out that poorly drained areas and compacted soils are particularly vulnerable.

He says a lack of strong freeze and thaw cycles to break up Midwest soils in recent years has allowed compaction layers to build, trapping moisture and stressing young roots.

Fertility also plays a defensive role. “Tissue sampling can show farmers where their nitrogen is, especially at an early stage,” Leahr reports in a press release. “Making sure nitrogen is adequate ... is key to minimizing risk.”

3. Set Realistic Expectations for Fungicides

While lab tests show that “Pam” and various Fusarium isolates are sensitive to common seed treatments and in-furrow fungicides, field results have been less consistent.

“Field trials in Iowa so far have not consistently produced crown rot to prove a clear yield or disease benefit,” Robertson notes.

Pioneer’s Essick agrees that while these products may suppress early infections, they aren’t a silver bullet. The most effective strategy remains maintaining overall plant health by reducing environmental stress and preventing insect damage to the roots.

4. Scout Early And Bring A Shovel

Farmers frequently notice crown rot at around dent stage (R5), but Robertson and Jackson-Ziems say the damage often starts earlier, between V3 and V6. They tell farmers to keep an eye out for stunted, pale or off-color plants in the midst of healthy plants.

“The first thing we might notice is that some plants may die early, and leading up to that, you might see some really odd discoloration. We call it ghosting—an off, ugly, greenish-gray color where the tops of the plant die,” Jackson-Ziems explains.

To confirm your suspicions, dig up the dead plant, wash the roots, and split the crown lengthwise. Look for brown, discolored tissue and root loss.

If you find significant “ghosting” in fields, Leahr recommends a proactive harvest strategy. “If you see a lot of ghosted plants in the field, consider making plans to harvest it early,” he says, suggesting a 5% threshold for prioritizing those fields.

5. Document And Share Your Findings

Because so much is still unknown about crown rot, on-farm data from affected fields is invaluable. Robertson and Jackson-Ziems encourage growers to keep detailed records of planting dates, soil conditions and hybrid performance.

Also, consider diagnostic testing of affected plants and sharing the results with your agronomist and university Extension specialists. What you share can contribute to a larger pool of knowledge about the disease. The faster researchers can identify which organisms are leading the “party” in your corn crop, the faster they can develop the tools needed to help you shut it down, say Robertson and Jackson-Ziems.

Beyond Bushels: Align High-Yield Strategies With Your Crop Budget

Mon, 29 Dec 2025 20:31:39 GMT

A practical crop budget can serve as a valuable farming playbook, offering essential direction and guidance from planting through harvest, according to farmers and business partners David Hula and Randy Dowdy.

“Return on Investment (ROI) is the primary focus for the year ahead,” says Dowdy, who farms near Valdosta, Ga. “Everybody is trying to figure out how to survive this lean time, because we don’t have $8 corn or $15 beans.”

Start The Season Strong

For Hula, the strategy for achieving both high yields and ROI begins with selecting the right hybrids and using excellent planting practices, followed by consistent nutrition.

“You want to feel optimistic that you’re going to have high yield potential starting out,” he says. “Then, you need to make sure the crop has all the groceries it needs, because if it runs out of juice at any one time, you’ve just hit the minus button.”

Power Of Finishing The Crop

Hula highlights that another critical component of maximizing ROI, even in current tight markets, is finishing the crop well.

He shares that despite having a challenging growing season this year, his dryland acres achieved their third-best farmgate average. He attributes that to ensuring the crop received the necessary resources late in the season, especially a fungicide application.

“We felt pretty confident [the crop] was going to deliver... and that was mostly because we finished it well. We were picking 66.7 to 67 pounds test weight corn at harvest,” reports Hula, who is based near Charles City, Va.

“Finishing the crop is by far where a lot of people leave a lot of yield on the table,” adds Dowdy.

Use ‘Bushels’ To Track Costs

The current market outlook for 2026 necessitates a sharp focus on expense management, Dowdy notes.

“Obviously servicing debt is still on everybody’s mind. A farmer should never cut out anything that he or she knows makes money. But the problem is sometimes they don’t always know what that is,” he says.

When planning the budget, Hula urges growers to shift their perspective away from the cost of the input and toward the bushel return needed to justify it.

He offers, as an example: “For me to do in-furrow, that requires seven bushels. If I’m not going to get a seven-bushel return per acre, I’m not going to do it.”

Hula believes the bushel ROI mindset should be applied to all inputs. By framing decisions in terms of bushels rather than dollars, he says growers can more easily see the economic impact of each investment they make.

Make Every Input Pay Its Way

Hula and Dowdy are spending significant time this winter consulting with growers on budget strategies through their business, Total Acre . In many cases, they are stressing the importance of refining in-season input applications to make them more efficient, rather than cutting them completely.

“We can keep some of the in-season applications and make them more efficient by placement,” Dowdy says. “The goal is not merely to cut costs, but to find better, more efficient ways to invest money that directly leads to a higher ROI.”

Dowdy and Hula discuss their budgeting recommendations in more detail in their latest Breaking Barriers With R&D podcast discussion on Farm Journal TV and YouTube via the link here:

Living Sensors Turn Soybeans into Fungal Disease Detectives

Mon, 08 Dec 2025 21:07:29 GMT

For Aidan Kleinschmit, trying to get the upper hand over white mold disease in soybeans used to involve a frustrating amount of guesswork.

White mold can lurk in soybean fields undetected for weeks, causing significant damage before any visible symptoms appear. Kleinschmit says his annual struggle with the disease turned a corner this past season when he decided to trial the use of CropVoice from InnerPlant.

“I remember they sent out an alert on a Saturday night about white mold being detected, and by Monday we had decided we were going to treat,” recounts Kleinschmit, who farms in northeast Nebraska with his dad and brother.

“That put us way ahead of the white mold, because by the time you see it some damage is done,” Kleinschmit adds. “You might get disease suppression from a fungicide at that point, but you’re going to have some yield loss.”

Early Detection: A Game-Changer For Disease Control
The proactive treatment Kleinschmit made included whole-field fungicide applications as well as some targeted spot spraying with a drone over 500-plus acres. The payoff was evident in yield results Kleinschmit saw at harvest.

“We sprayed one entire field in our bottom ground, and it made about 86 bushels per acre,” he says. “That was well over, probably 25 bushels better, than what some of the other fields in our bottom ground yielded.”

Gary Schaefer, chief commercial officer at InnerPlant, says the big takeaway with CropVoice is the tool gives farmers real-time disease detection, informing decisions on whether to spray a fungicide. This directly addresses the ambiguity that farmers like Kleinschmit have long faced with disease management decisions.

“CropVoice is designed to deliver ROI by either saving costs in years when spraying isn’t necessary, or by enabling timely, effective action during heavy disease pressure, significantly improving the efficacy and financial return of fungicide applications,” Schaefer says.

While Schaefer doesn’t say what the return-on-investment for using CropVoice is, he contends that for every dollar a farmer spends on technology or an input “they should get at least $3 back,” a number Kleinschmit affirms as being on par for his expectations.

A ‘Cell Phone Tower’ for Soybean Fields
CropVoice is the first product InnerPlant has designed for farmers. How the technology works hinges on a seed biotech trait the company has developed that turns soybeans into living sensors that detect disease at the molecular level. The soybeans emit a fluorescent optical signal within 48 hours of a fungal infection – before any visible symptoms appear.

The company is placing its soybeans in sentinel plots that act like an early alert system in a defined geography. CropVoice analyzes the data coming from the plots 24/7. If a foliar disease moves into the plots, farmers and retailers working with InnerPlant are alerted that the disease is in their area.

Schaefer says to think of the sentinel plots as working like a network of cell towers for farmers whose fields are the cell phones.
“What you’re subscribing to is the network of cell towers that gives coverage for a broad area,” he explains.

For 2026, InnerPlant is placing 100 sentinel plots in fields across Iowa, Illinois, Nebraska and South Dakota to achieve the cell tower network effect for farmers in those states. Each plot will range in size from one-eighth acre to one-fourth of an acre.

Cultural Practices Play An Important Role
The soybeans grown in the sentinel plots mimic the cultural practices representative of soybean growers in each state. The strategy ensures highly relevant data for farms that are enrolled in InnerPlant’s program, which is implemented through strategic partnerships with retailers, Schaefer reports.

Farmers enroll their soybean acres in the InnerPlant network for a fee ($6 per acre for 2026). Retailers facilitate the process, mapping fields into the company’s program for retailers’ continuous monitoring throughout the growing season.

Participating farmers get weekly scouting reports, which include a disease score indicating risk levels in their area along with a detailed map showing any disease progression in their area. In addition, the company provides real-time disease alerts that are pushed directly to farmers via text anytime CropVoice detects a disease in the sentinel plots in thearea.

“The plants will turn on to any fungal pathogen,” Schaefer reports. He says end-of-year scouting reports from 2025 in Nebraska and Illinois revealed the detection of between five and seven different fungal pathogens in the company’s plots.

Kleinschmit says the proximity of the sentinel plots to his soybean fields and the early text alerts are two of the factors that sold him on enrolling a portion of his acres in the program.

“We’re only going to spray acres that we think are going to be affected by white mold at this point. I thought the technology really gave us a good benefit there,” says Kleinschmit.

“There are so many variables and moving parts in farming, so if there’s a way to help minimize the guesswork to help us make a good decision, I’m going to look into it and try it,” he adds.

Other technologies are also being explored by researchers for early soybean disease detection, such as hyperspectral imaging for charcoal rot and the Sporecaster smartphone app from the University of Wisconsin–Madison. The latter predicts white mold risk based on weather data and field conditions.

Expanding the Network: Coverage for 2026 and Beyond
InnerPlant expects to scale up to more than 500,000 soybean acres across Iowa, Illinois, Nebraska and South Dakota in 2026 and plans to expand beyond those states over time.

To learn more about the technology, farmers can connect with participating ag retailers or reach out directly to InnerPlant.
Schaefer says the companyis hosting demos this winter, offering a firsthand look at this real-time, plant-based technology that could redefine how farmers address key diseases in the future.

He adds that InnerPlant will start field testing a corn fungal sensor in 2026, aiming to expand the plant-based disease detection technology to even more farmers and geographies in the coming years.

From Harvest to Hardship: Farmers Struggle With Cash-Flow Crunch

Tue, 25 Nov 2025 22:14:34 GMT

Across America’s heartland, most corn and soybean crops are harvested, combines have been put away, and farmers will gather with their families to enjoy the holidays ahead. But as farmers gather around dinner tables and give thanks for what they have, many are concerned about what they don’t have this fall – adequate cash flow.

That lack is the No. 1 issue facing farmers now, according to southeast Illinois farmer Sherman Newlin, who’s based in Crawford County.

“I think these low prices are starting to take a toll on guys trying to meet their cash-flow needs,” he says.

For many farmers, Newlin believes the issue isn’t just about surviving until next spring — it’s about paying land rents, covering input bills coming due, and staying afloat right now.

“Unless you’re in a good area that had really good yields, cash flow is probably going to be tight,” Newlin says.

Northeast Iowa Brent Judisch doesn’t sugarcoat the numbers he penciled out last Wednesday. “Our cash corn today is at $4.10 — that’s not going to cut it with an average yield. Our cash beans today are $10.60. With a good bean crop, that probably cash flows, but it doesn’t make any money,” he says.

Farmers Took Grain To Town At Harvest
Selling grain is about the only option many row-crop growers have had this fall to meet expenses, even if the market timing isn’t ideal, Newlin says.

“Prices for corn and soybeans have come up some. At harvest, things were quite a bit lower than where they are right now,” Newlin says. “But it’s kind of hard to take advantage of a rally if you sold across the scale and didn’t come back in and reown [the crop] on paper.”

Judisch says there are some “better bids out there” for farmers who can wait to market corn in late winter, February and March.

“But for the short term, [buyers] are not having to bid up that much to get it because guys are just having to turn some stuff into cash to pay the December rents,” he says.

(Ag Economists’ Monthly Monitor)

The November Ag Economists’ Monthly Monitor survey reflects farmers’ current cash-flow pressure as well as their mindset in how they are approaching marketing decisions now. The survey, administered by Farm Journal, shows:

53% of ag economists say farmers are marketing defensively, prioritizing liquidity and risk reduction.
41% of ag economists say farmers are reactive, delaying decisions due to uncertainty.

Where Is The Financial Stress Most Severe?
Jackson Takach, chief economist for Farmer Mac, tells Farm Journal his reports indicate farmers’ top concern is liquidity (working capital) and their second-highest concern is farm income.

“We know cash flows are top of mind,” he says. “As prices have come down, people are talking about it more and digging into working capital, and that’s causing a little bit of distress, particularly in the grain side of the ag economy.”

Takach says the economic stress is highest in parts of the country where soybeans are farmers’ No. 1 crop.

“You look at the Delta, that’s where we’re seeing a lot of stress popping up in bankruptcies as well as late payments, because of some of that additional stress coming through with lower commodity prices specific to soybeans.”

That sentiment is similar to what was shared in the November Ag Economists’ Monthly Monitor survey, though the Monitor paints a broader picture. When asked in which region farmers face the most severe financial pressure, economists reported that “cotton and rice country is suffering from especially poor profitability and weak sentiment.”

Without action, long-term farmer viability is at risk, according to John Newton, American Farm Bureau Federation economist. “Additional financial support is critical to offset trade losses and provide a bridge until farm bill enhancements from the One Big Beautiful Bill Act go into effect,” he says in a release. “This will stabilize the farm economy, sustain rural economies and maintain affordable food prices.”

Will China Come Through On Soybean Purchases?
The fate of soybean exports is on nearly everyone’s radar, especially as China’s purchases for 2025 still hang in the balance.

Reuters’ Karl Plume reports that China is starting to make good on its promises, noting that “two cargo vessels were headed for grain port terminals near New Orleans on Monday to load with the first U.S. soybean shipments to China since May, according to a shipping schedule seen by Reuters.”

But Judisch warns the window for 2025 U.S. soybean sales to China is closing fast.

“We’re going to have to see some immediate results from this agreement [with China], because if this drags into January and February and Brazil comes online, I’m not very optimistic that we’re going to make the goals that were set between the U.S. and China.”

Farmers Press On And Start Planning For Next Season
With 2026 around the corner, cautious optimism about the new year mingles with the current hard reality of farmers’ cash-flow drought.

Judisch notes that successful negotiations by the Trump administration to drop tariffs on some items, such as fertilizer, aren’t helping financially strapped farmers. He says that was a scenario of a little help that arrived too late.

“Stopping the tariffs on fertilizer this late in the game does no good for the 2026 crop because you’ve either got it on fields already or your buildings are already full of high-priced fertilizer,” Judisch contends.

“It’s kind of a bugaboo for us,” he adds. “Our costs are staying high even with the tariffs being dropped on fertilizer, but our income is just not going to be there until probably next summer.”

Cash rents for 2026 is one important aspect of the financial equation for the year ahead that 100% of ag economists surveyed this month recommend farmers dig into now. Notes one ag economist: “Cash rent could use more attention as a majority of land is rented… it would be nice if landlords knew that they may need to lower cash rent.”

(Ag Economists’ Monthly Monitor)

Newlin says he and other farmers he knows in his area are sorting through crop rotations for next season – whether to plant more corn and
fewer soybeans or less corn and more soybeans.

“We’ll probably be heavier corn next year just because of our rotation, but a lot of guys are going to be heavier in corn in our area,” Newlin says.

Judisch is sticking with his 60-40 ratio of corn to beans next season. Like Newlin, he believes other farmers could lean toward more corn in the year ahead, given the financial opportunity many believe corn offers.

“We’ve seen some very good export sales on corn, so there are some good things happening,” Judisch says. “We need to keep them going in the future. That’s the biggest thing.”

Southern Rust Delivers A Harsh Wake-Up Call For Disease Control

Mon, 24 Nov 2025 22:54:08 GMT

Southern rust swept through the Midwest this past summer, taking big bites out of corn yield potential and forcing many growers to consider making late-season fungicide applications they hadn’t budgeted for.

Now, many farmers are asking themselves and their agronomic advisers how to plan for next season. A common question: Is southern rust going to be a significant problem in the Midwest again in 2026?

The answer: No one knows. Southern rust does not overwinter in crop residue – it has to blow in on winds from southern climes to be a problem for Midwest growers. So, what happens next year with the disease depends largely on how Mother Nature behaves.

Another fun weather fact from summer of 2025...

— Pioneer Troy (@deutmeyer_troy) November 18, 2025

Fungicides Paid Their Way
If there’s any silver lining to the challenge many farmers had with southern rust this year it’s that now almost everyone knows how yield-crippling the disease can be and the value fungicides can deliver.

Mary Gumz says she was fielding calls from concerned corn growers as early as the V10 to V12 growth stages of corn.

“It was a very different scenario than we’re usually in most years, and we were recommending that farmers spray earlier than usual,” recalls Gumz, a Pioneer agronomy manager.

With the tough economics farmers faced this season, some opted to forgo an application. But where corn growers made the hard call and applied fungicide, those fields delivered at harvest.

“We got some big yield increases, and you could visually see the difference between those plants where we did make the early call [with a fungicide application] compared to the usual application at tassel timing,” she says.

Another factor that made southern rust so difficult to control this season is that, in many cases, a second application of fungicide was warranted where the disease had time to rebuild.

“You can get about two or three weeks of efficacy from a fungicide on southern rust, but don’t expect you’re going to get season-long control,” says Randy Dowdy, Valdosta, Ga., and partner in Total Acre . “I’m not aware of a fungicide that you can spray at tassel for southern rust and that will last 50, 60 days or until black layer.

Southern rust does not overwinter in corn residue like some other diseases, such as tar spot. Instead, if it shows up in the Midwest, it has arrived via winds from southern climes.

(Corteva/Pioneer)

Proactive Planning For Next Season Can Help
While southern rust is a concern, Kim Tutor, BASF technical marketing manager, encourages farmers to keep in mind those tough diseases, such as tar spot, northern corn leaf blight and gray leaf spot, that are annual disease challenges in the Midwest.

Tar spot overwinters in corn residue, ready to rebuild in corn crops when weather conditions are favorable to its development, and is making its way across the Corn Belt.

“Tar spot can be infecting a corn plant, causing damage internally for two to three weeks before we are able to detect a lesion or see symptomology on the surface of the leaf,” Tutor adds.

She says if you are in a situation where models show significant disease pressure is moving into your area or you are based in an area with tar spot pressure, for instance, to consider making an early application with a fungicide that has residual control during what she calls an optimized application window – as early as V10 and through at least R3.

If you are in an area with heavy tar spot levels or you are looking to push the envelope for yield, Tutor recommends making two fungicide applications in corn, keeping applications 20 to 28 days apart.

As for which fungicide you apply, for so-called driver diseases like tar spot or southern rust, Missy Bauer, Farm Journal Field Agronomist, recommends going with what she describes as “Cadillac” type chemistry, newer technology that features multiple modes of control.

Extension plant pathologists annually update fungicide efficacy ratings for various crops, including corn, via the Crop Protection Network website. You can check the ratings for each fungicide’s performance on various diseases using the Corn Fungicide Efficacy table. Some products work better on tar spot or gray leaf spot, whereas others are more effective on rusts and other diseases.

Given the outlook for grain prices next year, be sure to also check out the new Corn Fungicide ROI Calculator on the Crop Protection Network.
You can use the calculator to look at different scenarios (grain prices, expected yield, disease severity) to see the potential ROI on fungicide applications.

Currently data available in the calculator are from university uniform corn fungicide trials conducted across 19 states and Ontario, Canada between 2019 and 2022. Primary diseases in this data set were tar spot and southern rust.

Red Crown Rot Rising: What Every Soybean Grower Needs to Know For 2026

Tue, 18 Nov 2025 20:07:20 GMT

Red crown rot, a soilborne fungal disease that can cut soybean yields by 70% in severe cases, warrants consideration as farmers in affected areas finalize their variety selections and management plans for next year, agronomic experts say.

Historically prevalent in the southern U.S., red crown rot (RCR) is now moving northward with confirmations in at least seven key soybean-producing states since 2018, including Illinois, Indiana, Kentucky Minnesota, Missouri, Ohio and Wisconsin, according to the Crop Protection Network.

The speed at which the disease can move is illustrated by its progress in Illinois. A single infected field was identified there in 2018. Since then, RCR has spread to more than one-third of the state’s 102 counties.

In Minnesota, Ohio and Wisconsin, agronomists confirmed isolated cases of the disease in farmers’ soybean fields for the first time just this year.

“When the disease was found in Minnesota (Rock County) in August 2025, the nearest known location with red crown rot was over 400 miles away in NW Illinois,” says Dean Malvick, University of Minnesota Extension plant pathologist.

Compounding concerns is that the modes by which red crown rot is spreading into the Midwest aren’t fully known, he adds.

Red crown rot is on the move in the Midwest, with isolated cases confirmed in Minnesota, Ohio and Wisconsin soybeans just this year.

(Crop Protection Network)

Seed Companies Are Working On Solutions
“Most or all soybean varieties” adapted to the Midwest that have been evaluated by researchers to date appear to be susceptible to the disease, although differences in disease susceptibility have been reported, Malvick notes.

“Certainly, the seed companies are looking at resistance… and are getting some idea of what genetic backgrounds relate to resistance to red crown rot,” he said during a recent podcast .

While no soybean varieties are fully resistant, high-performing, disease-tolerant seed can help growers reduce the potential impact of RCR, according to Bill Kessinger, Stine technical agronomist.

Red crown rot can be tricky to identify early in the season, and its symptoms tend to be more prevalent in July and early August. On leaves, it often looks like SDS, showing yellowing and browning between the veins, according to Dean Malvick, University of Minnesota plant pathologist.

(University of Illinois plant pathologists)

Kessinger tells growers in affected areas he believes the No. 1 goal is to continue focusing on selecting high-yielding soybeans that will provide the best return-on-investment. Secondly, then consider how well those varieties score for resistance to RCR before making your final selections.

“We have to understand, with regard to seed, what we are going to give up compared to what we are going to get, and what risk we want to take as a grower,” Kessinger says. “It’s not an all or nothing decision … and everything still has to revert back to yield.”

BMPs And Seed Treatments Can Help
Integrated management practices are critical to addressing RCR, as the fungus overwinters and survives in the soil, reports Horacio Lopez-Nicora, Ohio State University assistant professor of soybean pathology and nematology.

“Once established, this pathogen is nearly impossible to eradicate, so integrated management is the only sustainable path forward to reduce its impact on our soybean crop,” Lopez-Nicora explains in an online article .

He says practices such as crop rotation with nonhost crops, improving drainage, using seed-applied fungicides and managing soybean cyst nematode populations — which can intensify red crown rot severity — will be important to farmers working to protect yields in RCR-affected areas next season.

Malvick adds that some seed treatment fungicides are reported to reduce the impact of red crown rot in soybeans.

“There’s more evidence building now that’s showing some of them work against both SDS and red crown rot,” Malvick says. “We don’t again have that evidence for the northern U.S. but we have enough information to say we probably have products that will be reasonably effective at least.”

Current soybean seed treatment options include Saltro and Victrato (pydiflumetofen, cyclobutrifluram; Syngenta), ILeVO (fluopyram; BASF) and Pretium SDS, a biological seed treatment (natamycin; Nufarm). Manufacturers advise checking with local retailers to see which seed treatment products are approved for use in your specific location.

AgZen, Corteva Team up on AI-Powered, Retrofit Sprayer Tech

Wed, 22 Oct 2025 15:08:47 GMT

AgZen announces an agreement with Corteva to further “explore the commercial potential” of AgZen’s AI-powered crop spraying optimization technology, RealCoverage.

The news comes on the heels of Corteva’s big announcement on Oct. 1 , detailing the crop protection multinational’s plan to split its crop protection and seeds businesses.

AgZen, a tech startup spun out of MIT, is making a name for itself by pioneering feedback optimization for spray applications — a new approach the company thinks has potential to improve farmer outcomes and reduce crop input costs.

(AgZen)

AgZen’s first product, RealCoverage, is a retrofit kit that can be bolted onto any sprayer to measure and optimize the number of drops of agrochemicals applied to crops. The system features a boom-mounted sensor that analyzes the coverage and quality of spray applications in real-time, displaying actionable data to a tablet mounted in the cab. Farmers can use the data to optimize the physical settings on spray rigs, both self-propelled and pull-behind, to increase coverage.

The startup says its system works by leveraging AI and cutting-edge computer vision, and customers have used RealCoverage to save 30% to 50% on input costs.

Northwest Indiana farmer Bryan Brost slapped a RealCoverage system onto his Hagie STS 16 high-clearance sprayer to use on his waxy corn and soybean crops. He says it has helped boost his spray program efficiency overall by reducing application rates while maintaining optimal coverage throughout his 12,000-acre operation.

“The payback came in the first year,” he tells Farm Journal via text message. “We have increased our acres [covered] per day with less hours on the machine, the operator and the nurse tanks supplying product [to the sprayer].”

Corey McIntosh set the technology loose across his 4,000 acre spread in Missouri Valley, Iowa. He is looking forward to using the data to improve his application efficiency across the board. He’s also letting his neighbors and local retailer in on the secret.

“I was getting a chem shuttle refilled at [the] co-op, these guys have always been complimentary of our weed control, I asked them: ‘What percentage of leaf surface area do you think you are covering with your sprayers?’ One of their best operators said he thought 50% coverage. The salesman next to him said it would definitely be more than 60%,” McIntosh says.

“They were shocked when I told them we were at 9% to 10%, but nobody has had ever had a way to quantify this before,” he adds. “We are really looking forward to making improvements.”

Since launching on the market in 2024, AgZen says it covered more than 970,000 commercial acres of application across the U.S. on row crops and specialty crops.

Some Farmers Are Increasing Cover Crop Acres to Cut Fertilizer Costs and Boost Soil Health

Tue, 14 Oct 2025 20:28:16 GMT

How can you trim fertilizer costs and still provide adequate nutrients for corn and soybeans next season? One solution is to consider planting some cover crops this fall, recommends David Hula, reigning world corn yield record holder.

“Nitrogen, potash, boron, sulfur… those are mobile nutrients, so if you plant a cover crop it’s going to pick up those nutrients, and then when you kill that cover crop, you can recycle that residue that was left over, or the residual nutrients that were left over,” explains Hula, who farms near Charles City, Va.

Cover crops can scavenge for nutrients from previous crops, store them and then release them for use the following season – a process that can help reduce the need for synthetic fertilizers.

Hula adds that corn and soybean growers don’t need to be using no-till on the farm to benefit.

“You can strip-till into those cover crops, or early in the spring you can work the cover crops in to get the benefits,” he says.

Randy Dowdy says one of the benefits he’s seen is that microbial activity likes to colonize around a living root mass.

“You know, it always helps our early season tissue sample values go up where we’ve got a cover crop,” says Dowdy, Hula’s partner in Total Acre . “So if guys can, at least on bean ground where they’ve harvested, get some cover crop established and get it up, from a biological play and nutrient availability play for next season, it’s a no brainer.”

Experience Has Increased Farmer Confidence
The survey data show that cover crop plantings are on the rise among farmers who already have experience using them, according to results of the September Purdue/CME Ag Economy Barometer. And, those growers will plant cover crops on a higher percentage of their total acreage this fall, reports Jim Mintert, emeritus professor of economics at Purdue University.

He says the survey trends point to broader adoption across acreage: This year, 57% of cover crop users planted them on 26% to 50% of their acres, compared to only 25% in 2021 who reported planting cover crops on more than one-fourth of their acreage.

“What the survey says is, if you use cover crops, you’re using them more intensively now than you did in the past,” Mintert adds.

He believes the increased use of cover crops by those farmers indicates they have figured out how to capitalize on the benefits.

“It’s like this learning curve, where maybe the folks that have learned how to use them are adopting them on a wider portion of their farm acreage. I think that is what we’re picking up,” Mintert says.

Where And Why Cover Crops Are Being Used
Cover crop use by farmers across the U.S. increased 17% between 2017 and 2022 – from 15,390,674 acres to 17,985,831acres – data from the 2022 Census of Agriculture show. In total, cover crops were planted on 4.7% of all cropland in 2022.

Regional differences in the use of cover crops are related to factors such as climate, soils, cropping systems, and state incentive programs, according to USDA-Economic Research Service.

(USDA-ERS)

For example, Maryland, which has the highest rate of cover crop use, has programs that encourage farmers to grow cover crops to help improve water quality in the Chesapeake Bay.

“Water quality is a big deal for those of us on the East Coast, and there are some programs available through NRCS and others that could be a little bit of a revenue stream for a grower and you can reduce some expenses,” says Hula.

Warm Conditions Could Help Stand Establishment
With the current fall conditions across the Midwest, Hula would encourage growers new to using cover crops there to experiment with them on some acres.

“A lot of times, Midwest growers are worried they’re going to run out of time to get a cover crop planted, but with as warm as it is, you have a good chance to get some growth established this fall and a good root system going before conditions turn cold,” he says.

Moisture is needed to get cover crops established well, and that is a concern in some areas this fall, cautions the Midwest Cover Crops Council. It says good soil moisture at seeding and 0.5” to 1” of rainfall after seeding will improve germination and stand establishment.

The Council has recommendations for which cover crops are a good fit by state and especially well-suited to farmers who are new to growing them. Learn more here .

Corteva's Bold Move: What Splitting Crop Protection and Seed Businesses Means for the Future

Wed, 01 Oct 2025 17:55:42 GMT

Global agriculture technology company Corteva announced plans on Wednesday to separate into two independent, publicly traded entities: “new” Corteva, which will continue to sell crop protection products – herbicides, fungicides, insecticides and biologicals – and SpinCo, which will focus on the seed genetics business.

SpinCo will include Pioneer, the company’s legacy seed brand established in 1926, as well as Brevant and regional seed brands, including Dairyland Seed.

Upon separation of the companies, Greg Page, current Corteva chairman, will lead new Corteva, while Chuck Magro, current Corteva CEO, will become CEO of SpinCo.

In announcing the decision by Corteva, Magro said the farmer-centric organization appreciates that its customers want and need choice across their input decisions.

“The best way, maybe I can even say, the only way for this company to preserve and expand that choice and keep putting innovative, effective, sustainable solutions into the hands of farmers around the world is to give both businesses the freedom to operate without having to look out for the other,” said Magro, during an online presentation primarily focused on company investors.

He added that the separation of the company into two entities will allow both businesses to maximize long-term value for farmers, customers, employees and shareholders.

Magro described SpinCo – with expected net sales of $9.9 billion in 2025 (56% of current Corteva sales) – as “a classic growth compounder” that will pursue opportunities in out-licensing, hybrid wheat, biofuels and gene editing.

“The continued success of our SpinCo business will be predicated upon sustained investment in advanced genetics and further capitalizing on our unique route to market,” Magro said.

As a pure-play crop genetics company, Magro predicts SpinCo could go beyond its corn and soybean core into other row crops, even expanding into other areas like fruits and vegetables.

“Spinco will also look to expand on new opportunities in wheat, cotton, rice and other products, where genetics can play a transformative role,” he said. “In other words, we could see SpinCo playing in a vastly expanded addressable market.”

Corteva Crop Protection Business Is Future-Focused

For new Corteva, Magro characterized the crop protection industry as competitive and tough, but that company leaders anticipate the market will return to growth in the near future.

“At new Corteva, success will be built upon an optimized supply chain, a new level of operational excellence and the ability to invest in the next generation of sustainable, differentiated innovation, including biologicals and other nature-based products,” he said.

Magro said as company leaders weighed the pros and cons of separating the two companies, they made the decision with the future in mind.

“This is not about today, and it’s not certainly about the last six years. This is about what we see coming,” he said. “We’re in a market that we need to look out 10-years plus. That’s just the research and development and the timeline it takes to bring technology into the marketplace. So this is a long-term decision that we are making.”

Corteva’s 2025 net sales for its crop protection business are estimated to be $7.8 billion (44% of the current company’s total).

During Magro’s remarks, he gave no indication of where the two companies will be based. Corteva’s global headquarters is currently based in Indianapolis, Ind., while Johnston, Iowa, is home to its seed business.

The transaction separating Corteva and SpinCo is expected to be completed in the second half of 2026.

Corteva was formed in 2018 as the agriculture-focused subsidiary of DowDuPont, following the merger of the two companies. Corteva was spun-off as its own entity in 2019.

Navigate 2026 Input Costs with A Proactive Strategy

Thu, 25 Sep 2025 19:06:10 GMT

While Brent Judisch is in the midst of combining his 2025 corn and soybeans, he’s also thinking about how to plan for next year’s crops and inputs specifically.

“Fertilizer prices will kind of mirror your corn prices usually, but right now they’re going opposite directions. That’s not something we can handle going forward on the farm, with the costs going up and income going down,” says Judisch, who farms in Black Hawk County, Iowa.

Price Trends For N, P And K This Year

Mark Tully, senior manager, global market research for Nutrien, tells Farm Journal wholesale nitrogen (N) fertilizer prices are up between 25% and 45%, depending on the product.

The increases are due to unexpected global supply constraints in 2025. “This trend is being driven by conflict in Europe, Middle East, and trade restrictions from China, which have all impacted production and export availability,” Tully says.

Phosphorus (P) and potassium (K) have also trended up this year. Tully reports wholesale phosphate fertilizer prices are up between 20% and 40% depending on the product, while wholesale potash prices are up about 15% from 2024 levels.

National Corn Growers Association (NCGA) projections indicate fertilizer expenditures alone could account for 36% of a corn grower’s operating costs in 2025, with little to no relief expected for 2026.

“Looking ahead to next year, [input costs] look to be going a little higher,” predicts Krista Swanson, chief economist for the NCGA. She says inputs for corn have totaled about $900 an acre annually for the past four years.

Trusted Advisers Can Help With Input Decisions

As farmers grapple with input decisions, Ken Ferrie encourages farmers to lean on their agronomists and other trusted advisers to help think through the process of where to allocate resources while still maintaining targeted yield outcomes.

For example, at current input prices, Ferrie says a corn grower might save $85 an acre by managing nitrogen more efficiently ($35), varying population according to soil type ($20) and switching to a non-GMO hybrid ($30).

“But you have to do your homework before you make these kinds of decisions or yields could potentially fall off a cliff, leaving your balance sheet in worse shape than if you’d made no change,” he cautions.

Judisch is looking to address higher input costs next year by trimming rates where soil fertility levels will allow him to pull back.

“I think we’ll probably trim back our phosphate usage [for corn] a little bit, but we’ll still go forward with potash, and you’ve got to have nitrogen. You really can’t cut there,” Judisch says.

Evaluate Purchasing Options Early For The Best Terms

Josh Linville, vice president of fertilizer for StoneX has been encouraging farmers planning to make fall anhydrous ammonia (NH3) applications to contact their suppliers now to lock in product.

While there is a good supply of NH3 in the pipeline currently, Linville is concerned the expected high demand could deplete its ready availability and lead to increased costs.

“I do think the prices will hold to push higher,” he says.

The best time for growers to contact suppliers to discuss 2026 availability and pricing of fertilizer, seed and other inputs is now, according to Jordan Howe, area manager for Nutrien Financial.

“Have an open conversation with your input providers, and explore options of early buying habits that could put you in a better position or help you capture a discount that maybe you haven’t in the past,” he says.

Howe encourages farmers to not shy away from asking questions of loan officers or financing institutions and read the fine print on any written agreement. Two key questions he recommends asking:

1. What is the price of the input if I want to pay for it in cash versus financing it?

2. If I opt to finance, what type of interest rate am I being offered – is it a fixed rate or a floating rate?

“I am seeing a lot ofunique financing opportunities out there where it might be a low, good rate early, but then it matures and turns into a much higher rate. You’ll want to consider whether you would be able to pay that off before it goes to the higher rate,” Howe says

He adds that being able to pay cash for some portion of your input needs can help you leverage your buying power to get the most competitive financing offers for the balance.

Don’t Forget To Consider Your Tax Implications

In the process of purchasing inputs for next season, keep in mind the potential taxes on products, recommends Jonathan LaPorte, Michigan State University farm business management educator.

“As you plan purchases, remember to maintain flexibility to maximize tax savings this year and next. Don’t overspend this year to save on inputs only to pay more income taxes next year,” he advises.

LaPorte offers an online Input Purchasing Plan Template in Word and Microsoft Excel to help farmers run different scenarios on input purchases based on their cropping plan for the year ahead. The template is available here .

5 Critical Insights From The Southern Rust Rampage In Midwest Corn

Tue, 16 Sep 2025 18:34:36 GMT

Northeast Iowa farmer Elliott Henderson sprayed a fungicide on part of his corn crop three times this season and nearly all of his crop twice, battling to break the chokehold of southern rust in his fields.

Henderson, who farms in Buchanan County, wasn’t alone in his struggle to contain the disease. Iowa State University (ISU) Extension estimates southern rust reached all 99 counties in the state.

Most corn growers were aware of the disease but hadn’t experienced the ruthless destruction it could cause.

For many, that changed this season.

The farmers Henderson routinely connects with are finding extreme yield losses now, as they start combining a corn crop that in many cases dried down and died prematurely. What occurred is common to southern rust – the disease pustules ruptured corn leaf surfaces, making it hard for plants to retain or regulate moisture.

“I made some calls around to see what guys are getting, and yields are down. I mean, we’re talking 30 to 60 bushels,” says Henderson. “We’re seeing guys with a 240-bushel APH, and they’re talking 180-bushel corn.”

An update on this field. The kernels are many but extremely small. The cob is almost rubbery. One ear doesn’t tell the full story, but this field did not handle southern rust well. #ISUCrops https://t.co/QDDtBWHa0r pic.twitter.com/fiYUboKN1E
— Meaghan Anderson (@mjanders1) September 12, 2025

Yield losses of up to 45% can occur from southern rust in severe cases, according to the Crop Protection Network (CPN).

Along with the yield loss, Iowa test weights are also taking a hit and could result in lower prices for growers. The official minimum test weight in the U.S. for No. 1 yellow corn is 56 lbs. per bushel and for No. 2 yellow corn is 54 lbs. per bushel, according to Purdue University Extension.

Henderson says he’s hearing farmers share test weight numbers well below those.

“We’re seeing lows in the 40s, some upper 40s, so it’s definitely being affected,” he says.

A Perfect Storm Of Disease Pressure
Plant health issues were the biggest challenge many corn growers in the Midwest encountered this season, Randy Dowdy contends.

“It was not a pollination issue. It was not a kernel development issue. We didn’t see the tight tassel wrap. It was disease pressure — that was by far the limiting factor for growers this year,” says Dowdy.

When he participated in the Pro Farmer Crop Tour in mid-August, Dowdy says he saw corn crops from Ohio to Iowa that were affected by multiple diseases. The four main ones were southern rust, gray leaf spot, northern corn leaf blight and tar spot — sometimes all four were on the same leaf in Iowa.

“Those growers that sprayed and stayed on it and understood that a fungicide couldn’t last but for 21 days at best, and made multiple applications, I think they’re going to reap the benefits,” says Dowdy in this week’s Breaking Barriers With R&D podcast.

You can watch this episode of the podcast on YouTube: Breaking Barriers with R&D: Late-Season Wins and Soil-First Strategies

The Crop Protection Network map shows where southern rust was confirmed in counties across the U.S. as of September 16. Notice how far north the disease traveled in Minnesota, South Dakota and Wisconsin.

(CPN)

Both Dowdy and David Hula, business partners in Total Acre , lament that many Midwest growers didn’t take a cue from their southern brethren and spray fungicides multiple times this season.

“Industry, in general, says if you spray at VT or tassel time, you can get by with one time. That is mostly accurate under a normal weather year,” Hula says. “But this year [some Midwest states] just had that explosion of southern rust, so they were dealing with a disease that’s historically not been a problem. You just had the environment for it.”

With growers beginning to plan what to do next season, Dowdy and Hula spent some time this week considering how growers can build an effective agronomic management plan for 2026.

Here are five of their key takeaways:

1. Formalize a plan to address disease (and pests, too).

“You have to stay proactive with your scouting and be willing to go with earlier fungicide or multiple applications, depending on what shows up,” Hula says.

In the process of being prepared to make multiple applications, keep in mind that you might not need all of them. While tar spot overwinters in stubble, southern rust doesn’t. The latter might not be a severe problem next season, as it is blows in from warmer climes.

Dowdy believes the weather system bringing southern rust to the Midwest this season originated in the Delta.

2025 Colfax County Nebraska Crop Tour results: 12 dryland fields, 207.5 bu. 2nd highest yield on record (2021 was 214). Stands were slightly lower than expected. Tar Spot lighter than expected. Southern Rust probably will reduce this yield. #25croptour pic.twitter.com/72VZCFMdZQ
— Chris Clausen (@ChrisClausen34) September 11, 2025

“Let’s face it, the incubator for you was the fact that you were wet and then had high, nighttime temperatures. It was hot, and you had corn everywhere, and you had a perfect environment,” he says.

Henderson agrees, noting moisture at the wrong time and too much heat were factors.

“We had a lot of heat right after pollination into that blister stage. We were stacking GDUs up really fast on that early-planted corn,” he recalls. “I do think some of this later planted corn is probably going to have a better experience finishing out.”

2. Work with like-minded farmers, agronomists and industry experts.

Be aware of disease pressure that is around you or headed in your direction by tapping into a local agronomist or groups such as the Crop Protection Network, and stay abreast of what’s happening in other regions.

“Everybody here is on pins and needles about southern rust every season, and we are constantly getting feedback from county [Extension] agents and industry, who are pushing the information out to the farmer, because everybody is well aware of the ramifications of southern rust,” Dowdy says.

Henderson, who works with Dowdy and Hula via their Total Acre program, also has a network of farmers in Iowa that he connects with on a regular basis.

“It’s a network of dozens of us farmers that call each other, bounce ideas off each other,” he says. “The things we’re talking about are often time-sensitive. It can be a daily thing.”

3. Understand how to use fungicides for maximum ROI, if you have given them little consideration in the past.

“It’s all about coverage,” Dowdy says. “Drone applications can be fine, but no matter what you do, if a guy is spraying two to three gallons, and you compare it to a ground rig spraying 15 to 25 gallons, I mean, there’s just no comparison in that coverage.”

Another aspect of coverage, Hula adds, is making sure the fungicide gets into the plant canopy far enough to have the desired effect.

“Fungicides have a tendency to work from the leaf they’ve come in contact with and move up,” Hula says. “So, if you’re trying to protect at least that ear leaf – and I like to protect the leaf opposite and below the ear – you’ve got to get penetration with that product.”

For a drone application, Hula says growers might have to spend a couple extra dollars to get sufficient volume for the product to get down below the canopy.

“If that’s what needs to be done, let’s do it,” he encourages. “If I’m spending $30 or more an acre, then I want to at least have the success that I’m paying for.”

4. Use products labelled for the disease issue you face.

That sounds like a no brainer, but in the heat of battle the wrong product can get applied, or you can select a product that isn’t up to the task.

With a tough disease like southern rust or tar spot, using newer chemistries with more than one active ingredient is also a plus.

5. Stay with your crop throughout the season; don’t walk away.

Today’s corn genetics tend to have more back-end potential to add yield through kernel fill.

It’s a key reason to evaluate what a fungicide application can do for a crop that’s advanced into one of the later reproductive stages, say Hula and Dowdy.

Brian Herbek, who farms near DeWeese, Neb., has leaned into their advice the past few years.

“I found out a couple of years ago, there’s a lot of hidden yield out there that a lot of us leave on the table,” Herbek reports.

What he learned from Hula and Dowdy is corn has the genetic ability – some hybrids more so than others – to pack starch into its kernels late-season to create higher test weights.

He scouts corn late-season to decide where to make “the finishing pass,” an application of fungicide or nutrients or some combination of the two.

“It’s not for every field. I’ll tell everybody that right now, there are certain fields that don’t deserve that attention,” Herbek says. “But if you know what you’re looking for, and you have that potential, that application does makes sense, but you’ve really got to know what’s out in your field.”

Dowdy and Hula share additional thoughts on how farmers can improve next season’s corn crop in the face of disease pressure in the latest edition of their Breaking Barriers With R&D podcast on Farm Journal TV and YouTube .

Southern Rust Set To Take Big Bite Out Of Midwest Corn Crop?

Wed, 27 Aug 2025 21:56:59 GMT

If one picture is worth a thousand words, then the video Iowa farmer Dan Striegel shot last week must be worth thousands more. In the video, Striegel is shown harvesting a field of emerald-green corn enveloped in a cloud of orangish-red southern rust.

“We were just getting that field opened up, and I looked over and saw that dust boiling up out of the chopper, so I shot the video,” Striegel says.

Southern Rust? Never heard of her.
What Cheer, Iowa. USA. #pftour25 #harvest25 pic.twitter.com/tiIsUc2CHl
— Dan Striegel (@djsinseia) August 21, 2025

To date, Striegel’s video has garnered more than 48,000 views on X, formerly Twitter.

“We’re in southeast Iowa, Keokuk County, and I think the southern rust is as bad here as it is anywhere,” Striegel adds. “Every field you walk in, if you’re wearing a white T-shirt, you’ll come out of there red.”

A Red Path Of Disease Mars The Midwest

Expect to see more red T-shirt-clad farmers walking out of cornfields across the upper Midwest, based on what the Crop Protection Network (CPN) southern rust map is showing.

The CPN continually updates its online, interactive map showing the counties by state where southern rust infections are confirmed. Now, in late August, the counties look like red steppingstones. They form a checkered path from southwest Michigan through northern Illinois and Indiana, into southern Wisconsin, across all of Iowa and nearly two-thirds of the way across Nebraska. Eastern South Dakota is also lit up with a string of red counties, as are parts of southern to central Minnesota.

The amount of southern rust present in the upper Midwest is worrisome to Ken Ferrie, Farm Journal Field Agronomist. In severe cases, the disease can wipe out 45% of the yield potential in a field, according to the CPN.

“At most, one in 10 growers in northern Iowa and Minnesota have seen the kind of southern rust some of them are seeing this year,” says Ferrie, who was working last week with corn growers in both states.

“It was a problem in probably eight out of every 10 fields I was in, and they’d all been sprayed at least once,” he says. “Minnesota has a corn crop that’ll knock your socks off – yield potential of 250, 270. I encouraged every grower to spray their field a second time except for two fields. One had been knocked down by hail, and the other had a hybrid that was clean.”

Hybrids Have Little To No Resistance To Southern Rust

A combination of early-season moisture, heat and wind formed the perfect storm for southern rust this season, allowing the disease-causing fungal spores (Puccinia polysora) to move from southern climes up to the Midwest, according to Kurt Maertens, BASF technical service representative for eastern Iowa and western Illinois.

“We’ve seen it all – southern rust, tar spot, northern corn leaf blight, gray leaf spot. Our corn has been inundated with all these fungal diseases, and we started seeing them early,” says Maertens.

If there’s a silver lining to southern rust, it’s that it does not overwinter in corn residue like tar spot does. But like tar spot, southern rust takes advantage of hybrids that have no built-in resistance. For many growers, that was an Achilles heel this season.

“When you’re dealing with a 117-day hybrid like they grow in southern Illinois, Tennessee, and Kentucky, you don’t grow corn that doesn’t have good southern rust resistance, because they deal with it every year,” Ferrie notes. “When you move to Minnesota, and you’re planting 102- to 95-day corn, you’re probably not going to find hybrids with southern rust resistance.”

Striegel says that was true for his neighbor’s cornfield, which he custom chopped for silage. “That field had two hybrids in it, one was worse than the other, and the field had been sprayed with a fungicide,” he says.

He adds that he also sprayed his own cornfields with fungicide, but they are still inundated with southern rust.

“We’ve had southern rust before, and it’s not usually something we have to worry about, but this is really bad,” Striegel says. “I’m standing on my deck looking at the cornfield next to my house, and you know, all of the leaves from the ears down in that field are covered with it.”

How Late Is A Fungicide Application Still Worthwhile?

Ferrie says the fields he scouted last week were at late R3 to early R4 and had already been sprayed with fungicide at least once, but the disease was rebuilding.

“Any field where farmers had sprayed two weeks previously, the southern rust and northern corn leaf blight, to a lesser degree, were coming back, especially the southern rust. It was resporating,” he says.

The intense disease pressure from southern rust, tar spot and others have kept fungicide use at high levels this season, despite poor commodity prices.

“Because of that [amount of disease pressure], we have seen increased demand for our fungicides this year,” says Maertens, who encouraged customers to get applications made at the beginning of tassel.

Maertens says he has fielded a lot of questions this summer from farmers, asking how late they could go with a fungicide application and still benefit.

“Our recommendation is to get in front of disease,” he says. “Generally, we stop applications before we get to dent (R5). That’s not to say a later application can’t have some benefit, but our best results have been before infection was able to take place.”

Southern rust is a yield enemy farmers routinely face in the Southeast, reports corn yield champion Randy Dowdy, Valdosta, Ga. He participated in the Pro Farmer Crop Tour last week and said on U.S. Farm Report he believes many Midwest farmers still have time to address disease.

“We need to implore the fungicides, the technologies out there and get after it and protect this crop, especially that crop that still has not reached dent,” he says.

Farm Journal Field Agronomist Missy Bauer likes to see farmers complete their fungicide applications on the front side of dough (early R4). “Once we get to early dent, I think it’s a little more challenging to get the payback consistently, though we’ve applied at early dent (R5), and seen a nice response,” says Bauer, who is based in south-central Michigan.

Under the tough disease pressure farmers are facing this year, Bauer is telling growers to scout fields and evaluate what growth stage their crop is in before they walk away or pull the fungicide trigger one last time.

She adds that farmers need to check the label to make sure the product used is able to address southern rust effectively. She describes these as “Cadillac” products containing the newest chemistry.

“When it comes to some of these diseases, especially southern rust and tar spot, I do believe a little bit of a Hail Mary pass can be effective,” she says. “Will it be as effective as an application you could have made on a more timely basis? Well, no, you could have made more money doing it timely, but you’re still protecting bushels and gaining ROI at the end.”

Ferrie adds that farmers might want to do the late-season fungicide application to keep their corn crop standing until they can put their harvest plan in place.

“Be doing the push test to check stalk quality,” he advises.

Southern Rust/Silage Alert!!

Southern Rust has been aggressively advancing in many fields, especially those without a fungicide treatment. In some situations the plants are shutting down prematurely and plant material is senescing rapidly.

— Pioneer Troy (@deutmeyer_troy) August 26, 2025

Striegel says some of the farmers around him are heading to fields to harvest their silage corn sooner than later, because of standability concerns. “Some of this corn got planted early, and we had a lot of heat. The crop matured quickly, and the diseases are kind of shutting it down. It’s just dying out, and guys are going to go get it,” he explains.

That’s the strategy Ferrie encourages farmers to use in regular production corn, too.

“Harvest the fields most at risk first. But if a field of corn goes down, go combine the fields where the corn is still standing and come back to that one later,” he recommends.

The reasoning is you don’t want to risk more corn going down while you’re harvesting the field of corn that already has.

“While I was driving through Iowa last week, I kept thinking that if I built corn reels to pick up down corn I’d bulk up my inventory, because I know where they’re going to get used,” Ferrie says, only half joking. “Yes, harvesting corn at 25% moisture is expensive, but down corn will kick your butt.”

As more than 100 crop scouts traversed dirt roads and two-lane highways, stopping dozens of times to sample corn and soybeans in seven Midwest states, they gathered insights to answer the question on many farmers’ minds this week: How would the Pro Farmer estimates compare to the numbers USDA-NASS released August 12?

The answer: Pro Farmer found a big corn crop but one that’s currently positioned to average 182.7 bu. per acre – 6.1 bu. below USDA’s 188.8 bu. projection.

“When we put the yield estimate out, it comes with a plus or minus 1% for corn and a plus or minus 2% for soybeans, and that’s because we know things can change yet,” says Chip Flory, host of AgriTalk and lead scout on the western leg of the tour.

“The other thing is the yield models that we use give us a range, and then, based on conditions, we can move within that range with the yield estimate that we’re going to pull,” he adds.

With that perspective in play, here’s how the Pro Farmer and USDA estimates compare:

Pro Farmer Corn Estimate (+-1%): 16.042 to 16.366 billion bushels; 180.9 to 184.5 bu. per acre average
USDA Corn Estimate: 16.7 billion bushels; 188.8 bu. per acre average

Disease Pressure Across The Midwest Is Concerning
The 2025 growing season has been marred by heavy disease pressure in many of the corn and soybean crops Pro Farmer scouts evaluated this week.

It was an issue Lane Akre says showed up repeatedly in corn and soybean fields from the get-go, as tour scouts fanned out to check 2,000-plus fields across seven states: Illinois, Indiana, Iowa, Minnesota, Nebraska, Ohio and South Dakota.

“We know disease can speed up the maturation of plants, making it difficult to keep them healthy long enough for optimal grain fill before harvest,” says Akre, Pro Farmer Economist and lead scout on the eastern leg of the tour. “We are concerned diseases like southern rust and tar spot could negatively impact corn yields in some of these states during the next few weeks.”

Soybeans Could Be the Star of the Season
USDA’s August estimate for the national soybean yield average is just slightly above what Pro Farmer scouts found in fields this week. Pro Farmer places the soybean yield average at 53.0 bu. per acre, with a total crop size of 4.246 billion bushels

By comparison, USDA expects soybeans to average a record high 53.6 bu. per acre, with a total crop of 4.29 billion bushels.

Pro Farmer Soybean Estimate (+-2%): 4.161 to 4.330 billion bushels; 51.9 to 54.1 bu. per acre

“One of the questions heading into the tour was whether the soybean crop could live up to the lofty expectations a lot of people have for it, and we found that it does,” Akre says. “There’s a massive crop out there in fields. We’re just hoping it can hold on until harvest – and outpace the disease pressure out there – to deliver on those big yields.”

Corn and Soybean Yield Summaries
Pro Farmer and AgWeb reported extensively throughout the tour — the highs and lows of each crop in each of the seven states. Here are summaries from each state. Click on the links to learn more details.

Illinois: Scouts reported an Illinois corn crop that looked lush from the road, but once they picked ears and pulled back husks, most described finding an average to above-average crop – not the record yield estimate USDA reported on August 12.

“The Illinois corn crop just wasn’t what we’d hoped,” Akre says. “USDA is anticipating a 1.7% jump from a year ago, and we’re actually down 2.2%.”

Indiana: Wet conditions from rain, fog and heavy due is causing some unevenness in Indiana corn and soybeans. Still, the state’s corn crop posted a yield number that came in 3.35% higher than its 2024 number.

From disease pressure to too much rain, some scouts found a solid soybean crop in Indiana, while other routes exposed extreme variability. Overall pod count numbers were down 2.30% from 2024.

Iowa: Scouts spent two days in the state gathering dozens of samples to gain insights and project yield estimates. Despite challenges from disease pressure, scouts reported a big corn crop with significant potential. Their estimates put the Iowa crop up 2.93% over 2024, and up 6.4% versus the three-year average.

“This Iowa crop has a very, very strong ear count, great grain inches — just a very consistent equation putting that corn yield together,” reports Emily Flory Carolan, Pro Farmer Crop Tour data consultant.

For soybeans, scouts found a massive crop, up 5.49% in the number of pods as compared to the 2024 crop.

Minnesota: The corn crop in Minnesota is currently heading for a record yield this season, if it can outpace disease pressure. Scouts recorded the longest grain inches in the corn there that have ever been measured in the tour’s history.

“That’s definitely what pulled up that yield average for us,” Carolan says.

Soybeans also show tremendous yield potential in Minnesota. Pod counts were up 20.38% this week versus 2024 counts, and up 19.9% versus the three-year average.

Nebraska: Adequate moisture is pulling up corn yields in the state this season, with some tour routes reporting 8% to 10% increases compared to 2024 and 2023. The much-improved corn yield estimates were a welcomed change, scouts say, after seeing corn there struggle in two back-to-back years of drought.

Soybeans also are promising big yield results, with pod counts up 15.0% this week over the 2024 estimate.

Ohio: Heavy rains last spring meant many farmers either got a late start to the growing season or they had to replant fields. The moisture extremes early on have resulted in considerable variability in fields from one end of the state to the other. Still, scouts say the Ohio crop has solid corn yield potential overall, citing possible records along some Pro Farmer Crop Tour routes.

The soybean pod factory in Ohio is going strong – with numbers up 4.66% this season over 2024 – but scouts caution a lack of late-season moisture is concerning. More rain is needed for the soybean crop there to finish well.

South Dakota: Based on USDA’s August crop estimates, scouts knew the possibility was there to uncover a big crop in South Dakota. Field estimates show record yield potential is possible , especially due to ample moisture this year that’s supported growth and development.

Soybeans might be an even better story in South Dakota this year. Pod counts came in at 15.9% above last year’s tour and well above the three-year average of 970.1 pods.

Revenge Applications: Why They Don’t Work, Cost You Money and Bushels, and Are Frankly Illegal

Fri, 22 Aug 2025 14:51:59 GMT

With sub-$4 corn, fungicide decisions were a bit harder this year, says Erin Marlow. But in the last two to three weeks, disease pressure has increased with identification of southern rust, gray leaf spot and tar spot.

“In some cases, you get into fields that have a little bit of everything, and it really starts to add up,” says Marlow, a crop consultant in Maryville, Mo.

But on Wednesday, she got three calls throughout the day that were easy answers. Farmers asked her if they should make a late season herbicide application.

“Most people aren’t going to spend money on something that they don’t see the value in, in a lot of cases,” she says. “This is being fed by emotion. There’s just kind of that psychological pull for it.”

Late-season weeds popping through the soybean canopies and tall green weeds standing out in browning corn fields have some farmers questioning if a late-season application can be a weed management tool.

“It’s difficult for a person to drive by a field they farm and see that,” Marlow says. “There’s this overwhelming feeling to try and do something. The education part for us is trying to explain to them that you’re going to hurt yourself more than you’re going to help yourself in this scenario.”

Marlow says for her geography, overall fungicide application is up this year over the average. And while talking with other consultants, she says this idea of a late season herbicide application is being fielded in Kansas, Iowa, Nebraska, Illinois, Indiana and Ohio as well.

Aaron Hager, Extension specialist, weed science/IPM at University of Illinois, gives three reasons why applying a herbicide right now is a bad idea.

1. The Weeds Are Too Developed
“Farmers are trying to clean up a mess that’s the result of either not getting complete control or another weed emergence event,” he says. “While fields may have looked clean on July 1, by the third or fourth week of July, weeds spike above the canopy. Now these are old plants — by now, rarely are these plants not already flowering.”

Marlow says the most expensive herbicide program is the one that doesn’t work.

“If we have late-season weeds, what we’ve been doing isn’t working. There are better and different options, which means we have to have a management shift,” she says.

2. It’s Illegal
“Each post product has its own application timing. For glufosinate, R1 is the latest application in soybeans,” Hager says. “There’s a reason for preharvest intervals — you can’t have pesticide residue on harvest crops. I’d hate to be the farmer who, because of a later-season application, meant an entire bin of soybeans was going to be condemned.”

3. There’s Adverse Impact on Yield
“The damage these weeds have caused in yield was weeks ago. They aren’t causing much additional loss for yield potential,” Hager says. “Applying a herbicide is throwing away your money, and you run the risk of adversely impacting the soybean yield.”

Marlow adds an example to illustrate the economic cost.

“If it costs $10/acre to add the herbicide to the tank, the yield loss in soybeans can be as much as 12 bu., and let’s assume it’s half of that you’ll lose 6 bu. at $10 beans. So, this could end up costing a farmer $70/acre.”

This is Nothing New
“These late-season herbicide applications have happened for decades,” Hager says. “That’s not saying it’s alright to do. Thinking there’s ROI on throwing in a herbicide with a fungicide application — it’s a complete misnomer.”

Hager says if waterhemp is the target species, this reinforces best practices to fight herbicide resistance.

“We’re never going to spray our way out of this,” he says. “We’ve tried for 30 years, and the only thing we’ve accomplished is speeding up the evolution for resistance against all chemistries.”

Marlow says farmers need to apply an updated lens for their weed management expectations.

“If we can get 90% to 95% control, that’s doing really good, and that could be a great expectation for chemistry,” she says. “However, if you have a field that has an area where waterhemp produced 100,000 seeds last year, with 90% control, that still leaves 10,000 waterhemp plants.”

As such, she says perfect weed control may be difficult to get to or may not exist. Once weeds start growing, they become even harder to manage.

What Can Farmers Do Different?
First, Hager and Marlow both say farmers need to understand the weed species they are targeting.

“We call them driver weeds because they drive your decisions,” Marlow says.

Second, choose the right chemistry programs.

Marlow advocates farmers use overlapping residuals in both corn and soybeans.

“We know we can kill weeds before they come up,” she says. “It’s important to choose a strong chemistry program and get applications done in a timely fashion.”

Crops vs. Foliar Diseases: A High-Stakes Race Underway in Midwest Fields

Fri, 22 Aug 2025 02:17:44 GMT

Two words sum up the concerns Pro Farmer Crop Tour scouts expressed about the corn and soybean crops they evaluated on Thursday in Minnesota and northeast Iowa: disease pressure.

Corn crops infected by southern rust and tar spot were a common sight in fields across both states during the fourth and final day of the tour.

“We saw disease in all of the fields we sampled today, though one of them really wasn’t too bad,” says Lane Akre, host of the eastern leg of the tour. “We saw a lot of early stages of tar spot, and we saw a lot of southern rust throughout.”

So it was no small surprise to the crowd attending Thursday night’s live broadcast when the final tally showed Pro Farmer’s corn estimate for Minnesota actually surpasses USDA’s 202-bu.-per-acre yield projection made August 12.

Pro Farmer estimates the Minnesota corn crop will average 202.86 bushels; that’s up 23.02% versus 2024 and up 13.41% versus the three-year average, according to Emily Flory Carolan, Pro Farmer Crop Tour data consultant.

“This crop is huge; it absolutely is,” Carolan says. “Minnesota is the only state on tour where we have recorded over a 200-bu. average this year. It is a record-year yield for the state.”

She adds that scouts recorded the longest grain inches in the crop that have ever been measured on the tour. “That’s definitely what pulled up that yield average for us,” she says.

Minnesota soybeans show similar yield promise, with final numbers pegged at 1247.86 pods in a 3' x 3' area. That’s up 20.38% versus last year, and up 19.9% versus the three-year average, Carolan reports.

A Much Better Growing Season, So Far
The findings in Minnesota were a pleasant change from what scouts found in 2024, when weather seemed to jog between two extremes – drought and flooding – for much of the season.

Jaden Serbus, Pro Farmer tour scout and farmer based near Renville, Minn., says he was relieved to see Mother Nature had course corrected.

“Last year, the corn crop was only as high as my head, all yellow and stunted with very, very poor yields with all the rain,” Serbus recalls. “This year, many areas are like a garden spot.”

Northeast Iowa Crops Look Good, But…
As Akre and his team of scouts moved into northeast Iowa on Thursday morning, early yield estimates had Akre concerned results there could bring the state’s overall averages down.

“We saw a lot of drowned-out parts of fields, and that’s limited some of the ear size and counts as populations are down due to skips,” he says.

Despite some agronomic challenges, scouts recorded strong numbers that put the Iowa corn crop at 198.43 bu.-per-acre yield average for 2025. That’s up 2.93% versus last year, and up 6.4% versus the three-year average.

“This Iowa crop has a very, very strong ear count, great grain inches — just a very consistent equation putting that corn yield together,” Carolan reports.

Iowa soybeans are also looking to break yield records. The 2025 crop delivered a 1384.38 pod estimate average in a 3' x 3' area on Thursday; that’s up 5.49% versus last year and up 12.94% versus the three-year average.

— Lane (@iwatchcorn) August 21, 2025

“For the most part, the Iowa beans are pretty lush and the pod counts have been there, the soil moisture is up, so the potential is pretty high on beans...I think that’s been the real story the last couple of days — how many pods are out there,” Akre says.

But foliar diseases rearing up in Iowa fields have the potential to put the kibosh on record yields between now and harvest, reports Chip Flory, host of AgriTalk and lead scout on the western leg of the tour.

That concern is one reason he reminded crop tour listeners on Thursday that Pro Farmer’s current yield estimates could change before combines roll.

“When we put the corn yield estimate out, it comes with a plus or minus 1%. The soybean crop estimate comes with a plus or minus 2%, and that’s because things can change. We all know that,” Flory says.

“The other thing is the yield models that we use give us a range, and then, based on conditions, we can move within that range with the yield estimate that we’re going to pull,” he adds, noting that he wonders whether the soil moisture currently available will offset some of the discount scouts put on the crops because of the disease pressure that’s present.

At the end of the day, August 21, no one knows how the final corn and soybean yields will net out. As Flory notes, while there’s optimism about better yields coming in this harvest versus a year ago, the outcomes depend on how well the crops cross the finish line.

Iowa Corn Has High Potential, Illinois Crop Looks Average and Soybeans Shine in Both States

Wed, 20 Aug 2025 23:58:45 GMT

Bright orange is a great color for pumpkins but not so much for corn. Nonetheless, that was the prevailing color Brent Judisch reports seeing as he evaluated crops Wednesday morning in northwest Iowa’s Harrison County.

“Our first six or seven samples were terrible with southern rust,” says Judisch, a Pro Farmer Crop Tour scout and Iowa farmer. “We saw three fields in a row that were actually gross. I walked out of them just covered with it. After that, while we’ve seen it all day, it’s been more in the lower leaves and not nearly as drastic.”

Chip Flory, lead scout for the western leg of the tour, says the northwest Iowa crop is the best and worst he’s ever seen.

“In the snapshot that we took of it, and the measurables we saw in the field today, it is the best corn crop,” Flory reported during the tour’s nightly live broadcast.

But the disease pressure in the Iowa crop has Flory spooked.

“Disease pressure is putting a lot of bushels — a huge number of bushels — at risk,” he adds. “You can take 20, 30 bushels off of corn yield with what southern rust can do to the crop, even at this late stage in the game. It’s a dangerous crop that we’re looking at out here right now.”

Chip Flory says he was surprised to see corn that was well into R5 (dent) in northwest Iowa. “I can’t tell if it was this mature because of pressure from the southern rust, or if it was because of higher nighttime temperatures at pollination,” he reports. “I am concerned about how much disease is out here, and what it’s going to look like in another week or two.”

(Chip Flory, Host of AgriTalk)

Can The Iowa Corn Crop Still Hit A Record?
The Iowa corn results were a big shocker on Wednesday, given the amount of disease pressure scouts saw, according to Emily Flory Carolan, Pro Farmer Crop Tour data consultant.

“I would say all three districts were setting new records. They were consistently high in all measurements for corn in ear count, inches long and kernels around,” she says.

Carolan’s summary of the results scouts tallied in Iowa revealed some high yield estimates, despite the disease pressure:

*District 1 was 197.89 bushels, up 12.06% versus 2024 and up 9.89% versus the three-year average.

*District 4 was 207.25 bushels, up 5.82% versus last year and up 14.01% versus the three-year average.

*District 7 came in at 195.03 bushels, up 1.80% versus 2024 and up 6.35% versus the three-year average.

(ProFarmer)

Flory is concerned southern rust will impact standability in the Iowa crop, which he says is starting to dent in areas, and cause some of it to go down.

“I’d want to keep an eye on the stalk condition of this crop, because if this disease pressure continues, farmers are going to want to get out and prioritize fields for harvest before we get there,” he adds.

Illinois Corn Crop Looks Average
Scouts report the Illinois corn crop appears lush from the road, but once they walked out into fields, picked ears and pulled back husks, most described finding an average crop.

“We’ve seen some good corn, we’ve seen some average corn and we’ve some stuff that’s got a long way to go,” tour scout Jake Guse told U.S. Farm Report’s Tyne Morgan on Wednesday morning.

That perspective played out in the total results tallied and shared during the nightly tour meeting. Illinois corn averaged 196.19 bushels per acre, down 2.24% from last year but up 1.72% from the three-year average.

(ProFarmer)

— Darren Frye (@Frye_WSS) August 20, 2025

USDA-NASS estimates released August 12 project the Illinois corn crop will come in averaging 221 bu. per acre for the state, up 4 bushels over 2024.

That’s outside what Guse’s expectations are for the state.

“As you’re driving along the road, you can see ears that are already tipped over. I just don’t see it reaching [USDA’s projection],” he says.

Lane Akre, Pro Farmer economist and host for the eastern leg of the tour, agrees with Guse. He reports pulling several samples of corn that exceeded 200-bu. per acre as well as one that only hit 143 bushels.

“The Illinois crop just wasn’t what we’d hoped,” Akre says. “USDA is anticipating a 1.7% jump from a year ago, and we’re actually down 2.2%.”

Akre’s leg of the tour went through three Illinois counties that are typically heavy hitters for corn yields: Bureau County, Henry County and Rock Island County.

“There’s really good dirt through that area, and the farmers there are very good at actively managing their crops and what they do with fertilizer, herbicide and fungicide,” Akre notes. “We saw some poor emergence and that might’ve weighed on the samples we took.”

Soybeans Could Be the Star of the Season
Soybeans offered a better yield picture for Illinois farmers than the corn crop, Akre notes.

“We didn’t have a single sample in the state that was south of 1,300 pods in a 3’x3' square. We saw a lot of pods and a lot of potential out there,” he says.

The average counts Illinois scouts recorded was even higher than what Akre found, with an average of 1,479.22 pods in a 3’x3' square area. That is up 4.24% versus 2024 and up 12.65% versus the three-year average.

(ProFarmer)

Iowa soybean results across the three districts were equally impressive.

“This year’s crop is better than last year by far,” Greg Lehenbauer, Pro Farmer crop scout, told AgDay’s Michelle Rook. “They’ve had adequate rain across this part of Iowa almost all summer long.”

Carolan’s data confirmed the excellent soybeans that crop scouts found on Wednesday in all three districts:

*District 1 soybeans: 1,279.25 pods, up 15.38% versus 2024 and up 15.05% versus the three-year average.

*District 4 soybeans: 1,376.15 pods, up 9.73% versus 2024 and up 13.63% versus the three-year average.

*District 7 soybeans: 1,562.54 pods, up 14.37% versus 2024, and up 24.66% versus the three-year average.

(ProFarmer)

While Flory is cautiously optimistic about the Iowa soybean crop, he says stem rot and sudden death syndrome is taking root in more fields and threatening yield outcomes.

“Some of the routes through southern and west-central Iowa have seen a tremendous amount of disease issue on the soybeans, so I’ve got a feeling it’s going to look a lot different in a week than what it does right now,” he predicts. “Now, if it was September 10, that’d be one thing. But it’s August 20, and there’s still time for those bean diseases to take some yield away.”

Flory’s sentiment about what fields revealed in Iowa was shared by scout Brent Judisch.

“What it’s going to come down to here in the corn and the beans is, does the crop mature faster than the disease moves, or will disease outpace the crop?” Judisch says. “We won’t know for sure for another two or three weeks.”

R5 Growth Stage Holds Hidden Yield Potential

Wed, 20 Aug 2025 16:09:55 GMT

As your corn crop turns the last corner of the 2025 growing season and heads for the finish line and harvest, there is still a lot of potential yield to be made or lost in the process.

The R5 growth stage (dent) – the next to last growth stage for corn – is one of those key times in the season where your management practices and Mother Nature’s cooperation up to that point can influence harvest outcomes.

Dan Quinn, Purdue University Extension corn specialist, explains the reason: kernel dry matter content in a corn crop at the beginning of R5 is only at roughly 45% of the eventual final accumulation.

Another way to look at that – there is still up to 55% of the kernel dry weight left to be accumulated by the crop, starch that can contribute significantly to grain fill and yield.

“Therefore, if significant environmental stress (drought, nutrient deficiency, etc.) were to occur during beginning R5, significant yield losses can still occur,” Quinn writes in this online article .

Many of the newer hybrids seed companies have developed are designed to add bushels by increasing the amount of starch in kernels, according to Ken Ferrie Farm Journal Field Agronomist.

“That’s one way we obtain yield increases without raising populations,” Ferrie says.

Keying Into The R5 Growth Stage
Michigan farmer Nathan Baker addresses the importance of R5, in his most recent video, posted to YouTube on Monday .

In the video (starting at about 24 mintues), Baker is evaluating his early-April planted corn, which is starting to reach dent (R5). Of his entire 2025 crop, he says it is the most advanced field of corn he has, noting there is some disease pressure present.

“That is northern corn leaf blight. You can see it started with a lesion here, and it has spread. There’s another one. I don’t like to see that…but there’s nothing drastic,” Baker says, pointing to some damaged areas on a corn leaf.

Baker says he used fungicide to rein-in disease pressure. In some fields, he made two applications.

(Nathan Baker)

Knowing the importance of late-season grain fill is a key reason Baker says he made the investment in applying a foliar fungicide some weeks earlier.

“That’s why it’s important that we … take care of these plants late in the season and keep packing that starch in there, giving it all the nutrients and the things that it needs. It’s why I still really, really want some rain, because we can still use it to help make this corn crop better,” he says.

Baker gives a shout out to his AgriGold agronomist, Wayde Looker, for the insights he learned about the R5 growth stage.

Look For The Milk Line In Kernels
As corn moves into the R5 stage, you can start to see a distinct line near the top of kernels, which is the milk line. This line indicates the division between the dry and liquid material in the kernel.

The R5 growth stage in corn can occur approximately 30 – 40 days following silking and is defined when nearly all kernels are ‘dented’ at the crown of the kernel and hard starch or solid endosperm has begun to form.

(Dan Quinn, Purdue University Extension Corn Specialist)

As kernels harden, the line moves from the top of the kernel down to where the base attaches to the cob. Keeping an eye on the milk line’s progression is useful to corn growers who cut crop for silage or are trying to determine when to stop irrigating. It’s also helpful for growers trying to determine how much time is left before the corn reaches maturity and will be ready to combine.

Quinn says corn moves through the early part of R5 quickly and then slows as it nears physiological maturity (R6, black layer). Overall, from the beginning of R5 to maturity is about 33 days:

3 days — from the start of R5 to the quarter milk line stage
6 days — from quarter to half milk line
10 days — from half to three-quarters milk line
14 days — from three-quarters milk line to black layer

Actual time to black layer may vary depending upon the hybrid and the environment. However, this is a guide that lets you know what to expect and help you plan for harvest, Quinn says.

Ken Ferrie: Central Illinois Corn Yields Look Close To 5-Year Average

Thu, 14 Aug 2025 17:34:22 GMT

Disease pressure is ramping up in central Illinois corn but the crops have widely varying degrees of infection, according to Ken Ferrie, Farm Journal Field Agronomist.

The biggest issues area growers are dealing with now are tar spot, southern rust and some northern leaf blight. Some farmers are responding by making a second fungicide application, while others are sitting tight, given the tough economic climate.

Understanding it’s a tough call on whether a fungicide application will pay for itself, Ferrie tells growers to stay the course with their fields and make crop evaluations so they can adjust yield expectations and marketing decisions, if need be.

“I’m out here looking at these fields every day, and each one’s kind of its own surprise,” he says.

Corn Yield Potential Is Still Solid
Ferrie recalls that last season he saw a lot of central Illinois fields come in at harvest with 300-plus bushel yields. That’s not his expectation this season, though he thinks farmers could still see an above-average crop depending on what happens during the next few weeks.

“My highest yield estimate so far this season has been 297 bushels, dividing by 80. So there’s definitely a difference in what we’re yield-checking here in central Illinois compared to a year ago,” he says.

“If we compare it to the five-year average, we’re probably going to be satisfied. If we compare it to last year, we could be disappointed,” he adds.

Check Disease Tolerance Scores By Hybrid
Where hybrids had rain in July, Ferrie is seeing tar spot explode in the ear zone. With southern rust, the disease is more scattered in fields, with some more heavily infected by the disease than others.

Matt Duesterhaus is more concerned currently with southern rust in western Illinois, where he’s based, though he expects tar spot could come on stronger in a couple of weeks. He tells farmers hybrid susceptibility needs to be a consideration in the decision whether to spray a fungicide now.

“Once we get from beginning dent into full dent, it’s pretty hard to make a fungicide pay unless you’ve got a susceptible hybrid, one that makes a lot of its yield in kernel depth. So we’ve got to pay attention to those hybrid ratings,” says Duesterhaus, field research agronomist for Crop-Tech Consulting.

He encourages farmers to check their hybrid scores for tolerance to diseases they identify in their specific fields and then weigh the decision whether to make a fungicide application now.

“The tolerance gives you a starting point on scouting,” Duesterhaus says. “Depending on the tolerance, southern rust can take down one hybrid to where you’ll be picking up [combining] down corn, versus in the next hybrid, it might only be a 10- or 20-bushel hit.”

Along with evaluating disease tolerance in hybrids, Ferrie says to consider whether your hybrids are D hybrids—those that count on depth of kernel fill to get their yield punch.

“Their depth of kernel comes at the end of grain fill — the last half of the 60 or so days after pollination through black layer,” Ferrie explains. “They need to stay green as long as possible and finish the season strong. Many new hybrids are D types.”

Southern Rust Has Infected Iowa Corn in ‘Likely Every County’

Mon, 11 Aug 2025 20:53:56 GMT

Alison Robertson says she has been at Iowa State University (ISU) for 21 years, and she’s never seen as widespread a problem southern rust is in Iowa this season. She believes the disease is present in every one of the state’s 99 counties.

She reports the disease moved into Iowa early, right at the beginning of grain fill.

“I’ve never seen this before…we’re just going to have to see how bad it gets,” Robertson, an ISU Extension field crops pathologist, told AgriTalk Host Chip Flory.

Corn yield losses from the disease can reach 30% and even more, depending on infection severity.

Karen Braun, chief market analyst at Zaner Ag Hedge and a Pro Farmer Crop Tour scout, says one of the fields she’s watching in western Iowa is “in pretty bad shape, disease-wise.”

“It’s really hard to get a feel for how widespread [southern rust] is, but I know a lot of people are talking about it, especially with how much moisture they’ve gotten out in the western belt,” she told Flory on AgriTalk.

Southern rust has infected corn in at least 18 states as of Monday, according to the Crop Protection Network (CPN). Along with Iowa, the CPN has confirmed the disease in other Midwest states, including Illinois, Kansas, Minnesota, Missouri, Nebraska and a “probable” finding in Michigan.

“Southern rust loves wet, and the fact that we saw it early and we’ve been wet means the disease is really ramping up,” Robertson says.

What The Disease Looks Like On Plants
Southern corn rust, caused by the fungus Puccinia polysora, creates round, light brown to orange spots scattered mainly on the upper leaf surface. They might also appear on husks, stalks, lower leaf surface and ear shanks.

“We’re getting all these spots, pustules on those leaves that are producing spores,” Robertson says. “When the spores are produced, they burst through the leaf epidermis, and so because of that, those leaves are probably losing a little bit more moisture than they would do with something like Northern corn leaf blight, or gray leaf spot, or even tar spot.”

Tissue damaged by the disease is not able to photosynthesize. Corn kernels are then unable to fill with starch and build a heavy test weight.

“The plants are under a lot of stress trying to fill that grain, so that can lead to premature senescence and just death of those plants,” Robertson says.

Southern rust can be difficult to distinguish from common rust .

Many Farmers Still Have Time To Treat The Disease
Foliar fungicides can help farmers manage southern rust, but timing is critical. Research shows fungicide applications ideally go on the crop from tasseling through the milk stage (R3).

“And if you have a severe infection into dough, then a fungicide application could still be helpful. But once you get to R5, once that corn is denting, it’s too late, you can’t do anything,” Robertson notes.

The Crop Protection Network, a multi-state Extension resource, offers a new mapping tool called Crop Lookout farmers can reference to identify various diseases and their locations.

“If you just click on that, there’s a couple of hot links on that map for tar spot and southern rust. When we find new spots of disease, it’s updated in real time,” notes Daren Mueller, an ISU Extension pathologist.

Robertson has posted an article online with more information on Southern rust continues to develop across Iowa.

Fast Facts About Southern Rust
· Southern rust spores can travel miles on air currents.
· Once infected, symptoms can be observed within three to four days if the weather is favorable.
· Within seven to 10 days, spores are produced and can travel to other plants.
· Favorable southern rust conditions include hot temperatures and at least four hours of consecutive leaf wetness.
· Research shows southern rust can continue even with temperatures around 110°F.

Artificial Intelligence Joins The Fight Against Weeds, Insects And Disease

Thu, 07 Aug 2025 19:45:30 GMT

The crop protection industry needs a reboot, according to Tony Klemm.

As CEO of Enko, a crop-protection startup, he says the company is taking a different approach to solving one of agriculture’s biggest problems – developing safe, effective and sustainable crop protection products that can be brought to the marketplace faster and more economically.

Traditional discovery pipelines for herbicides, fungicides, insecticides are not keeping pace with real challenges farmers face, such as resistance issues, he told Chip Flory, host of AgriTalk on Thursday.

A 2024 study funded by Crop Life International reports the costs associated with bringing a new active ingredient to major U.S. and European markets now top $300 million. In addition, the survey says the average lead time between the first synthesis of a new crop protection molecule and its subsequent commercial introduction is now over 12 years.

Part of the long development time required is related to regulatory hurdles. “There’s just increasing demand for meeting environmental safety needs, rightfully so,” Klemm says.

A Paradigm Shift
Enko, based in Mystic, Conn., is using artificial intelligence (AI) and a machine learning discovery platform to guide the company’s research and development efforts. Klemm describes the strategy as a paradigm shift from the current industry practices for how small molecule crop protection discovery has been done.

“We use DNA-encoded libraries, and these libraries allow our scientists to explore this massive, diverse chemical space in a very targeted, automated and expansive way,” he says.

The technology allows Enko scientists to look at billions of molecules and screen them for safety and efficacy and, in the process, develop them faster and more economically.

“We still have to take the regulatory journey that, right now, no one’s figured out a way to expedite,” he notes. “But getting to that regulatory queue faster and better on the front side is really what’s bringing us that cost savings, that efficacy and is going to allow for more products to be put into the regulatory queue in a faster manner.”

Progress To Date
So far, Klemm says Enko has delivered about 50 active programs that cover all facets of weeds, insects and disease. Many use novel or new modes of action that Klemm believes will help farmers fight resistance issues, such as herbicide resistance in Palmer amaranth and pigweed.

“We’re really working on how we can bring new modes of action to farmers, give them fresh tools to win that fight. And our chemistries work using fewer active ingredients, from perspective of the load on the acre, so we’re designing safer chemistry for the future,” he says.

Specifically, Klemm says Enko recently announced a new grass herbicide is in the pipeline for the European cereals market for control of black grass. The company also has conducted field trials for corn and soybean products in the U.S. that he anticipates are five to 10 years away from market launch, depending on how long they take to move through regulatory channels.
