A prematurely collapsing ear shank stops grain fill, leading to yield reductions that can reach as high as 40%.
The Midwest crop is being pushed into black layer (R6) prematurely in some areas in ways that are easy to confuse with normal drydown factors.
The disease is causing turmoil for farmers who have a large crop in the making. In some cases, a Hail Mary fungicide application at R4 up to early dent (R5) might make sense this season, say agronomists.
The online platform currently has about 500 programs and service providers in the Midwest participating and is a free resource for farmers, ranchers and their advisers.
“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.”
The Minnesota corn crop is going for gold. Pro Farmer Crop Tour scouts expect the crop will reach a record 202.86 bu. average, if it can outpace southern rust and tar spot. Scouts peg the Iowa corn crop at a 198.43 bu. average, but it also faces disease challenges.
Iowa could be the nation’s top state this year for corn and soybeans, but both crops are in a race to beat disease pressure that’s gaining momentum. Illinois corn continues to ride the struggle bus, while the soybean crop there is positioned to deliver high yields.
There is still up to 55% of the kernel dry weight left to be accumulated by many corn hybrids at this point — starch that can contribute significantly to grain fill and higher test weights.
With at least four weeks left in the growing season, Ferrie encourages farmers to stay ahead of heavy disease pressure in fields, particularly in what he calls D hybrids — those that punch their yield card late-season.
Corn yield estimates in seven counties surrounding the community of Bloomington indicate farmers there will harvest an average crop, at best. That’s counter to what USDA predicts for Illinois yield results statewide.
The extent of the disease in the state is the worst one ISU Extension pathologist says she has ever seen. Farmers in 17 other states have also confirmed the disease.
Short-stature corn is often planted at higher populations because its architecture allows for better light interception and more efficient use of resources when plants are grown closer together. But that’s not always the case, according to Ken Ferrie, Farm Journal Field Agronomist.
Camaraderie is cathartic. It lifts spirits, gives encouragement and reminds all of us we are valuable. Check out what farmers have to say about this year’s corn crop – the good, the bad and the in-between – and may their experiences lighten your load in the process.
A crop-protection startup is using AI and machine learning to identify and develop new active ingredients it says will help farmers solve issues like weed resistance faster and more economically.
USDA reports 73% of the corn crop nationally is in good to excellent condition – a 5% increase over this same time in 2024. Industry analysts believe the Aug. 12 Crop Production report will boost its estimate for the 2025 crop because of the overall favorable growing season.
Just as corn growers were ready to put their pollination problems behind them, another one comes along. This time, the issue had to do with moisture occurring at the wrong time, and the results are significantly impacting yield.
The industry investigates the agronomic issue finding it can be attributed to many factors including environment, genetics and rapid growth stages.
Got tar spot? Economic data shows two passes can offer ROI, depending on the hybrid. However, if your crop got dinged at pollination that’s a different scenario and might require a revised game plan that takes yield estimates into consideration.
More reports of ‘overly tight tassel wrap’ are coming in across the Corn Belt – including from the reigning world champion corn grower. Hula shares how he strategically uses his planter to minimize pollination risks.
An up-and-down early growing season in the Upper Midwest left many soybean farmers with small, stressed soybean plants. Find out what the carbon penalty is and learn strategies to beat it and save the crop.
Both diseases are showing up earlier this summer than last year, according to Daren Mueller, Iowa State University plant pathologist. He says a new interactive tool from the Crop Protection Network can help farmers locate these diseases, and others, faster.
So far, the problem has been confirmed in four states. Agronomists are encouraging farmers to scout crops, estimate yield impacts in affected fields and determine whether to make adjustments to marketing plans.
This year’s program features all new agronomic content to help farmers grow and harvest high-yielding crops. Two of the key sessions: selecting a corn planter that’s right for your farm, and developing a systems approach to success with early-season soybeans. We look forward to seeing you there!
Many early-planted soybeans in the Midwest are in the R2 to R3 growth stages now, ideal treatment timing for most disease issues. Agronomists offer three reminders to help you make the call — plus a fourth tip on herbicide rescue treatments.
Farmers and aerial applicators tell Randy Dowdy and David Hula some of the key considerations for effective fungicide applications are timing, droplet size and product reach in the crop canopy.
New Rabobank research shows the potential effect of losing this critical shipping channel to the global fertilizer market.
Unlike most leaf diseases, tar spot starts impacting the crop at the bottom of plants. That means fungicides you apply must penetrate and get deep into the crop canopy to provide effective treatment. If you opt to not treat the disease, consider making plans to harvest early and pre-booking some dryer gas.
Live every Wednesday at 11 a.m. and 1 p.m. central, the free weekly sessions will give CCAs, agronomists, practitioners, and producers with science-backed, field-ready insights.
Scott Beck says the family-owned business markets seed corn in 23 states now, with Nebraska ranking fifth in the total volume of seed units sold. Once finalized, this latest acquisition will be the company’s furthest west production facility.
Wheat streak mosaic virus decimated some fields this season, say K-State Extension specialists. The problem is also showing up and expanding in other key wheat-producing states. What farmers do this fall will determine whether the disease is reined in or takes off again next season.
