Post-emergence herbicides for corn and soybean

Liz Bosak, Outreach Specialist, Department of Agronomy

At this time of the year, integrated weed management programs focus on scouting and diversifying management practices including non-chemical methods and herbicide sites-of-action. For more information, please visit the United Soybean Board’s TakeAction website, http://takeactiononweeds.com/manage-your-fields/ and http://takeactiononweeds.com/understanding-herbicides/sites-of-action/ . Michigan State University’s Weed Science website has detailed web pages on common weeds in annual crops with biological information and management recommendations, http://www.msuweeds.com/worst-weeds/ . After each field season, the Herbicide Evaluation Program here at the university publishes efficacy data in a research report available at http://wcws.cals.wisc.edu/research/herbicide-evaluation-program . Summary ratings for many weed species are located in “Pest Management in Wisconsin Field Crops” available as a free pdf or in print at Cooperative Extension’s Learning Store, http://learningstore.uwex.edu/Pest-Management-in-Wisconsin-Field-Crops2015-P155.aspx .
