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 .
