Agronomists are finding pests, plant diseases and in some areas weather related crop damage in corn and soybean fields. Find out what they are finding in the Corn Belt states of South Dakota, Ohio, Michigan, Minnesota, Iowa, Illinois and Indiana.
“First, I was surprised that Adapt-N and our Soil Scan 360 testing found so much of the 150 to 160 pounds of N applied in the spring could be lost by the summer. And then I was surprised that when we added 50 pounds of N per acre by plane in June, there was a 30 bushel per acre yield increase.”

"We've found you can use most herbicides with fall seeded cereal rye with very few problems, but when you get into annual ryegrass, legumes or forage radishes, you start seeing more limitations."
-- Bill Curran, weed scientist, Penn State University...More
Almost all postemergence soybean herbicides have a preharvest interval or a soybean developmental stage beyond which applications cannot be made specified on their respective label. Failure to observe the preharvest interval may result in herbicide residue levels in the crop in excess of established limits....More
Although complete elimination of spray drift is impossible, problems can be reduced significantly if you are aware of major factors that influence drift, and take precautions to minimize their influence on off-target movement of droplets....More
Around the Midwest, agronomists from WinField are out in corn and soybean fields, checking on crop development and looking for weeds, insects and diseases. Development varies across the Corn Belt, and some states are seeing disease and weed pressure.
Around the Midwest, agronomists from Winfield are out in corn and soybean fields, checking emergence issues and looking for weeds, insects and diseases. They're also checking for nutrient deficiency. Here are updates on what they're seeing.
The labels of most postemergence corn herbicides allow applications at various crop growth stages, but almost all product labels indicate a maximum growth stage beyond which broadcast applications should not be made. This table lists herbicides and the max corn height at which it can be applied....More
EPA’s draft report on the ecological assessment of the herbicide atrazine contains numerous data and methodological errors and needs to be corrected. Atrazine is an important tool for sustainable agriculture deserves a thorough and comprehensive scientific review....More
