Precise Spray Droplet Sizes for Optimizing Herbicide Applications April 10, 2018

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.

Herbicide label section
Figure 1. A careful read of the herbicide label provides important legal and educational information for your weed management program. An example of a group 2 herbicide from the sulfonylurea family and a list of other herbicides that belong to the same group and family. Paying attention to the group name makes it easier to ensure that herbicide(s) from the same group are not repeated within a growing season or the next year.

What Should You Look For in a Herbicide Label January 26, 2018

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 on the Impact of Dicamba Micro-Rates on Non Dicamba-Tolerant Soybeans January 10, 2018

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.
