Insects
Yield losses of 10 bu. to 35 bu. per acre are common in affected cornfields, especially where farmers have a later-planted crop and in those fields with L2 hybrids.
Resistance and continuous corn are boosting populations of this yield-robbing pest.
Guard X is applied in-furrow and provides an alternative to traditional insecticides used to combat corn rootworm.
One report says heat unit thresholds for the pest to develop have been met/exceeded in parts of states such as southeast Kansas, central Missouri, central/southern Illinois, central Indiana and western/central Ohio.
Research underway at the University of Nebraska-Lincoln is showing promise by targeting western corn rootworm genes with RNAi technology.
BASF’s new website, SCNFields.com, is dedicated to helping growers manage risk against Soybean Cyst Nematode.
Tymirium and Adepidyn are both fungicides, while Plinazolin is an insecticide and Syngenta’s fastest-growing technology to date.
The distribution agreement focuses on Vestaron’s Spear Lep insecticide, which is a peptide-based control method meant to provide growers with a more environmentally friendly alternative to traditional chemicals.
In a year with razor-thin margins, at best, corn and soybean growers can use a variety of new technology and tried-and-true agronomic tools to score higher yields this season.
Data — a word that packs a punch but can be hard to define. From planting to irrigation, it’s necessary to have a digital record of these field activities to participate in sustainability and crop traceability programs.
Don’t take equipment to fields too soon and create headaches that will linger all season. While you wait for the right timing, consider doing prep work and projects that can help set you up for yield success.
During testing, the company found only 4% of CRW larvae chose roots treated with TS201 when given a choice between treated and untreated roots.
Corn growers can use this free tool to understand which hybrids have which traits, as well as evaluate insect problems and herbicide needs in-season.
AMVAC reports on-farm trials found corn treated with BioWake Prime had an increase of 8 bu./acre win advantage over grower standard practice.
Gravista-D can be applied as a pre-bin treatment and on post-harvest grain as it flows into storage for extended residual insect control.
To help growers create an effective management plan for controlling soybean cyst nematode (SCN), the SCN Coalition shares five key steps to take.
Coragen eVo contains three times the active ingredient concentration, which results in a lower formulated product use rate.
The Prescriptive Pathogen Report uses predictive soil analysis to predict the field pressure and economic risk of corn rootworm in the upcoming growing season.
BioWake Prime is an EPA-registered bioinsecticide with technology that is designed to protect against the effects of corn rootworm.
Poncho Votivo Precise from BASF offers a combination of protection to address nematodes and early-season insects in soybeans. The product contains a biological and insecticide.
If you’re tempted to build a beehive in your backyard, think twice. And instead of resorting to thoughtless prohibitions in the name of favored insects, let’s look for innovations trusting farmers to do the right thing.
The SCN Coalition’s new SCN Profit Checker tool allows growers and their crop advisors to estimate the financial toll of soybean cyst nematode in each field.
The pest is showing up in early-season soybeans. Current numbers don’t necessarily warrant treatment. Because the pests can double in population in only a few days, scouting is the only way to stay on top of them.
Bayer Crop Science has unveiled a novel approach to the discovery and development of crop protection solutions, called CropKey. Company officials say it is helping them bring new products to the marketplace faster.
Several factors converge making corn rootworm, black cutworm and true armyworm a high concern this season.
From lubricating booms to cleaning and replacing spray tips, ace mechanic Dan Anderson emphasizes the importance of prioritizing upkeep during the spraying season.
Similarly, Ken Ferrie says to time your post-herbicide application in corn based on weed size and to address cutworm based on the level of damage you find. One pass in the field could work for both, but don’t bet on it.
Agronomists are reporting high numbers of black cutworm and true armyworm moths in pheromone traps. Their offspring, the larvae, can do serious harm to corn. So can the offspring of four other common moth species.
Farmers in some states can expect BCW damage in corn by mid-May. One larva can ruin five corn plants in a 24-hour period. Rescue treatments are most effective and economical -- not seed treatments or Bt hybrids.
True armyworm (not to be confused with fall armyworm) is moving into Midwest wheat and corn crops now. Many are newcomers from the South, but homegrown populations are also concerning in Illinois, Indiana and Michigan.
