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.
"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 emergence issues and looking for weeds, insects and diseases. They're also checking for nutrient deficiency. Here are updates on what they're seeing.
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.
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
In the 5 ag stories to read this week, get some resources for managing resistant weeds and get payment estimates for farmers who used the ARC-CO program for 2015. Learn about members of the public who help test water quality and see photos of nutrient-deficient corn and soybeans. Finally, enjoy some creative bale stacking!
Around the Midwest, agronomists from Winfield are out in corn and soybean fields, checking planting progress, emergence issues and looking for weeds, insects and diseases. Here are updates on what they're seeing.
Bruce Ackley, Ohio State University weed science specialist, breaks down the differences between Palmer amaranth, waterhemp and redroot pigweed in a recent video. From stem differences, leaf shape, hair presence and seed heads, Ackley shows you the differences between the three plants so you can properly manage the difficult weeds....More
