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.
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.
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.
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.
The Rise of Multiple-Resistance in Nebraska’s Weeds and Effects Of Dicamba Micro-Rates on Sensitive Crops
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics on how to diversify weed control methods and modes of action to reduce potential development of resistance.
Nitrogen on Soybeans — the Hope Never Dies
November 6, 2017
Nebraska Soil Scientist Charles Shapiro offers a synopsis of two new publications, both with University of Nebraska authors, that address the question of the nitrogen deficit between soil supply and nitrogen fixation and what affects whether increased nitrogen leads to increased yield.
