How Widespread is Group 15 Herbicide Resistance in Illinois Waterhemp Populations?
Illinois soybean farmers face a major challenge as waterhemp weeds have developed resistance to multiple herbicides, including Group 15 herbicides confirmed in 2019. A project funded by the Illinois Soybean Association and led by the University of Illinois Urbana-Champaign aims to evaluate the prevalence of this resistance and provide farmers with management recommendations.
Contributors Needed for Weed Mapping Project
Scientists are working to track troublesome weeds across the country by creating and updating weed distribution maps. They are seeking help from crop consultants, agronomists, and weed scientists for this project.
Wet Spring Weather and Nitrogen Loss Revisited
With May's rainfall continuing following a wetter-than-usual April, concerns regarding nitrogen (N) losses are on the rise. In this farmdoc article, Giovani Preza Fontes and Emerson Nafziger talk about the concern of how much N will be available for the 2024 corn crop and determining the optimal timing for additional N application.
Can Henbit Serve As A Host Away from Soybean?
Illinois Soybean Association Outreach Agronomist, Stephanie Porter, CCA, shares the challenges of winter annual weeds, highlighting henbit and purple deadnettle as alternative hosts of soybean cyst nematode. Research suggests that managing winter annuals in the fall, applying residual herbicides, and removing winter weeds before planting are crucial strategies for management.
Learning From the Integration of Soil Health, Water Quality and Climate-Smart Agriculture
A multi-year Illinois Soybean Association project led by Dr. Andrew Margenot is benchmarking tillage and cover crops effects for soil health and water quality. Results will inform farmers of tradeoffs among soil health, carbon credits, and water quality.
