Management of herbicide-resistant weeds in corn-soybean cropping systems is a challenge for Nebraska growers. Six weeds have evolved resistant to glyphosate in Nebraska and particularly glyphosate-resistant marestail (horseweed), waterhemp, and Palmer amaranth are widespread in eastern Nebraska and kochia in western Nebraska. The United Soybean Board (USB) Take Action initiative and university weed scientists across the Midwestern United States have developed a free webinar series covering various weed and herbicide management topics. Each webinar will have two weed scientists giving presentations for about 15 minutes and there is opportunity for viewers to ask questions via the web portal. Recorded webinars can be viewed at a later date by following the links below.

Every Thursday, February 27 to March 26, 10 am CST.
