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.
Wet Conditions Delay Planting as Other Regions Race to the Finish
In the latest ILSoyAdvisor podcast, Abigail Peterson, CCA, and Stephanie Porter, CCA, from Illinois Soybean Association discuss the current planting and crop conditions in Illinois. They cover mid-May to June soybean planting recommendations and address the latest issues with weeds, cover crop termination, and pests.
Checklist for Late Soybean Planting (Mid-May to June)
If you're planting soybeans from mid-May to June, refer to this checklist from Illinois Soybean Association Agronomist Stephanie Porter, CCA, for insights on seeding rate, row spacing, maturity, weed management, disease control, and more.
How Will Planting Delays Impact Yield?
In this episode, the Soy Envoys discuss recent field activity, highlighting variability in conditions with some regions dry and suitable for planting while others remain wet. They also discuss significant weed pressure, reports of black cutworm feeding in both corn and soybeans, replanting, and more.
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.
Is It PPO Damage?
In 2024, weather conditions have shifted from ideal in March to cool and wet from April into May, raising concerns about herbicide applications, seedling diseases, and emergence issues. IL Soy Envoy, Eric Beckett, CCA, focuses on the use of PPO inhibitors which are crucial for preemergence weed control but may raise some alarms of unsightly-looking soybeans as they emerge and begin to grow.
May Weather Update: Heavy Rains and a Slow Start
Matt Reardon from Nutrien Ag provides a May weather update, highlighting the frequent rainfall in Illinois that has increased soil moisture and alleviated drought concerns. He also discusses the long-range forecast, indicating the potential for continued wet conditions through the end of May and a warmer, stormy summer ahead.
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.
Planting Progress: Don’t Hit the Panic Button Yet!
Tune in to hear the Soy Envoys provide the latest field updates in this episode, where they discuss the sporadic planting progress and share their top concerns. From herbicide application to emerging pests and prevent planting, stay informed on the pressing agronomic issues impacting farmers.
