Consider Label Restriction of Soybean Herbicides Based on Geographical Region in Nebraska
April 16, 2020
There are several herbicides that cannot be applied in certain areas of Nebraska based on number of factors such as high soil pH, dry soil conditions, potential for carryover injury, etc.
Consider Weed Growth Stage for Optimum Control with Liberty Application
May 23, 2018
Consider these three guidelines to ensure maximum weed control with Liberty in LibertyLink corn and soybean and view a time-lapse video demonstrating how quickly waterhemp regrows when treatment occurs after the optimal weed height of 4 inches or less.
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.
Herbicide Options for Managing Glyphosate-resistant Common Ragweed in LibertyLink Soybean
March 1, 2018
Results from a 2017 weed management trial on glyphosate-resistant ragweed indicated two applications were often more efficient and cost effective than either three applications or one application of herbicide.
Preplant Tillage to Manage Glyphosate-resistant Common Ragweed
February 13, 2018
Nebraska university weed scientists conducted research in 2017 to identify the effect of preplant tillage on weed emergence in an effort to develop an integrated weed management plan to control glyphosate-resistant weeds. Here's what they found.

May 24, 2017
Several factors have contributed to delayed applications and marestail escapes this spring. Includes recommendations for timely postemergence control in corn and soybean.
New Research Quantifies the Dispersal of Glyphosate Resistance Trait Through Pollen-Mediated Gene Flow
May 18, 2017
The pollen-mediated gene flow was detected 38% to 54% at 0.1 meter distance and 5% to 9% at 50 meters, the highest distance tested in this study.
Nebraska Extension Pest of The Month: Horseweed
January 5, 2017
Horseweed (marestail, Conyza canadensis L.) is a unique weed species that can emerge in both fall and spring. In Nebraska, unlike the eastern Corn Belt, horseweed populations predominantly emerge in fall as a winter annual.
