A two-year weed management study in northeast Nebraska evaluated herbicide options for controlling buckbrush, a common perennial weed in Nebraska pastures and rangeland. One herbicide provided year-round control, while several others provided season-long control.
Cottonwood offers many benefits, but also can be an invasive and difficult-to-control weed. Nebraska researchers studied control efficacy of eight herbicides over two years and found three products provided total control more than a year; however, they also noted a caution for areas with high water tables.
Researchers tested two herbicide strategies in soybean to see how preemergence herbicides would delay the critical time of weed removal, likely reducing the number of herbicide applications needed in a season.
Researchers tested three preemergence herbicide strategies in Roundup-Ready Corn to identify how their application affected the critical period of weed control — the period when weed control is essential to avoid yield loss.
Researchers report on a study to confirm the level of sensitivity of grapes and tomatoes to 1/10 and 1/100 of the label rate of dicamba. The studies were conducted with pot-grown grape and tomato plants during the summers of 2016 and 2017 at the Haskell Ag Lab.
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.
