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.
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.
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.
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.
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.
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.
