Competitiveness of Herbicide-Resistant Waterhemp with Soybean

September 26, 2018

The objective of this study was to evaluate the competitiveness of three herbicide-resistant Nebraska waterhemp populations with soybean in a greenhouse environment. The results indicate the importance of enhancing early-season crop competitiveness.

CoAXium™ Wheat Production System and Aggressor™ Herbicide for Controlling Grassy Weeds

August 30, 2018

A new herbicide-tolerant wheat production system was officially unveiled in 2018 and offers growers a new means to control grassy annual weeds in wheat.

Fall Strategies for Weed Control in Winter Wheat

August 29, 2018

Managing weeds at least two weeks prior to planting winter wheat and then controlling winter annuals this fall are important to reducing disease, saving soil moisture, and achieving top yields next summer.

Can You Help Weed Scientists Assess IWM Knowledge and Use?

How much do you know about Integrated Weed Management (IWM) strategies and their application to your operation? What information do you need?

Use Shredding, Grazing to Manage Pasture Weed Flushes

August 17, 2018

Extra rain this summer has made many pastures greener than they've been in a long time, but unfortunately, some of that green is likely to be weeds. At this point in the season shredding and grazing may be more effective than applying a herbicide.

Dicamba’s Effect on Soybean Node Numbers

August 8, 2018

Do soybean continue to produce a new node every 3.7 days despite being injured by off-target dicamba exposure? That was the question examined in this on-farm study.
