8 Points to Success With Postemergence Herbicide Applications
June 19, 2019
Many crop fields did not get the early-season residual herbicides they usually would, placing a heavier reliance on post-emergence programs this year. Following these eight guidelines can help assure safe, effective POST applications that minimize the potential for off-site contamination.
How Clean is Your Sprayer? Study Participants Needed
May 10, 2019
University researchers are seeking 30 Nebraska spray applicators for a sprayer cleanout study. The study will help extension application educators learn about applicator practices and how to direct their educational efforts.
Research Report: Prevalence and Mechanism of Atrazine Resistance in Waterhemp from Nebraska
October 26, 2018
Researchers studied waterhemp populations in eastern Nebraska to evaluate the efficacy of PRE and POST herbicide applications and the mechanism of atrazine resistance. Here's what they found and take-home messages to apply to your operation.
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.
Precise Spray Droplet Sizes for Optimizing Herbicide Applications
April 10, 2018
Achieving the most effective and consistent spray droplet size helps provide for precision application of pesticides, which saves input costs and reduces off-target movement. University researchers using a pulse-width modulation sprayer studied the best droplet size for effective weed control with six herbicides used in Nebraska crop production.
Managing Pesticide Applications for Me and the Environment
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics on managing pesticide applications to reduce drift and other forms of off-target movement.
Spraying the New Phenoxy Herbicide Formulations in Xtend and Enlist Soybeans Will Present Challenges
May 11, 2017
The new phenoxy herbicide formulations, including Enlist Duo™ (Dow), XtendiMax® (Monsanto), Engenia™ (BASF), and FeXapan™ (DuPont), offer growers new management options along with new application requirements. To alleviate problems related to applying new phenoxy herbicide formulations in soybeans as well as to increase herbicide performance, manufacturers have established application requirements. Here we discuss some of the key application factors to consider.
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.
