If you're considering planting winter wheat next fall, be sure to review the corn and soybean herbicide programs you plan to use this spring to avoid rotation restrictions that would limit your cropping options.
Achieving the most effective and consistent spray droplet size helps provide for precision application of pesticides, which saves input costs and reduces off-target movement. University researchers using a pulse-width modulation sprayer studied the best droplet size for effective weed control with six herbicides used in Nebraska crop production.
A herbicide label is a legal document providing important information about a herbicide, its appropriate use, and the precautions needed to avoid off-target movement and to protect environmental quality. It can also help you achieve the most efficient and sustainable application. Learn more about what to watch for on herbicide product labels.
Research at the university's Haskell Ag Lab at Concord in 2016 and 2017 studied the effects of microrates of two dicamba products applied at one of three soybean growth stages. The trials showed that non-dicamba tolerant soybeans were sensitive to even very low micro-rates of Engenia and XtendiMax; response varied according to amount and growth stage, with exposure at later stages having less effect.
When applying postemergence herbicides, consider corn growth stage, weed species present, and crop and weed heights. The article includes how to determine corn growth stage, recommendations to avoid problems, and a table of application restrictions for common postemergence herbicides.
