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.
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.
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.
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.
Potential Off-Target Dicamba Movement from Corn Applications
February 15, 2018
While the new soybean dicamba herbicides were often blamed for injury to sensitive plants in 2017, a deeper look at the timing of injury and the weather conditions at those times suggests dicamba applications in corn may have contributed to plant injury in many areas. Increased management for all dicamba applications will be needed in 2018.
Can We Manage Dicamba Applications in 2018?
February 15, 2018
Factors leading to dicamba injury and how growers will need to practice best management practices with all dicamba applications in 2018 to help reduce injury to susceptible crops and other plants. This article discusses key practices to implement.
Removing Dicamba Residues from Your Sprayer: A Tricky Task
February 15, 2018
Thoroughly cleaning your sprayer both before and after applying dicamba is required and can help reduce the potential for off-target damage. Check these recommended practices and see what research at Mississippi State University found when testing sprayer hoses.
