Research Update: Control of Perennial Invasive Weeds Requires Repeated Herbicide Applications
June 4, 2018
Research shows the need for patience and persistence when battling perennial weeds such as purple loosestrife over multiple years. The younger the stand the faster the control was achieved.
Considerations for Postemergence Dicamba-based Herbicide Applications to Corn
May 31, 2018
With postemergence herbicide applications occurring to corn, consider these best management practices to improve results and reduce the potential for off-target injury from your dicamba application.
Study: Efficacy of Herbicides in Buckbrush Control
May 22, 2018
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.
Research Findings on Chemical Control of Cottonwood
May 22, 2018
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.
Preemergence Herbicides Delayed the Critical Time for Weed Removal in Soybean
May 16, 2018
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.
Preemergence Herbicides Influence the Critical Period for Weed Removal in Roundup Ready Corn
May 11, 2018
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.
Sensitivity of Grape and Tomato to Micro-rates of Dicamba-Based Herbicides
May 3, 2018
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.
Planning Ahead for Winter Wheat: Review Corn and Soybean Herbicide Programs
April 13, 2018
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.
