Dicamba Off-Target Injury Continues in 2019 in Nebraska

August 16, 2019

As the crop season progresses, questions about dicamba off-target injury in soybean, broadleaf crops, and trees are increasing in Nebraska. If you suspect off-target injury in one of your fields, here's a reminder of what to do.

8 Points to Success With Postemergence Herbicide Applications

June 19, 2019

Many crop fields did not get the early-season residual herbicides they usually would, placing a heavier reliance on post-emergence programs this year. Following these eight guidelines can help assure safe, effective POST applications that minimize the potential for off-site contamination.

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.
