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.
Using Drones for Weed Management
In this GROW Farmer Forum, panelists led a discussion of the current state of drone scouting, mapping and herbicide applications for weed management, as well as the future of the technology. Dr. Steve Li, of Auburn University, served as the moderator, alongside panelist Rick Jordan, of CNY Drone Services.
Planting Marches On: Addressing Concerns with Herbicide Applications, Weather Forecasts, Cover Crop Termination, and More
The Soy Envoys provide an update on planting progress across Illinois, with both corn and soybeans at 11 percent completion as of April 21st. They discuss emerging concerns such as weed pressure, pest sightings, cover crop termination, and adhering to herbicide labels.
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.
Integrated Weed Management Maybe the Answer to Herbicide Resistance
Herbicide resistance poses a significant challenge for farmers, prompting the need to explore diverse strategies for weed management. In this episode, Michael Flessner and Karen Corrigan discuss GROW's (Getting Rid of Weeds) comprehensive approach, emphasizing collaboration, research, and outreach for greater diversity of weed control strategies to complement chemical use.
Weed Control for Early Planted Soybeans
Dr. Hager's research found the most reliable weed control program for early planted soybeans involves a full rate of PRE plus POST herbicide application, while reducing PRE rates often leads to variable weed control. Delaying PRE herbicide application increases the risk of weed emergence before treatment, highlighting the importance of integrating both PRE and POST applications to minimize weed competition with soybeans and reduce seed return to the soil seedbank.
Changes to Dicamba-Containing Products Used in Soybean
On February 6, 2024, a federal court in Arizona vacated the labels of three dicamba-containing products used for in-crop broadleaf weed control in dicamba-resistant soybean varieties. Following the Arizona court ruling, EPA issued an order to allow application of existing stocks of these three dicamba-containing products previously registered for application in dicamba-resistant soybean varieties.
The Challenge: Winning Against Weeds
In this Better Beans presentation, Meaghan Anderson highlights how rapidly waterhemp resistance is outpacing herbicide development. She emphasizes the need for custom herbicide programs and for farmers to adopt non-chemical strategies.
Optimizing Your Weed Control Strategies for Success
Exploring effective weed management strategies, Dr. Karla Gage presents on weed control and integrated approaches at the Illinois Soybean Association's Better Beans event held at Rend Lake College in southern Illinois.
Year in Review: Unpacking Agronomy Highlights of 2023
Join Kelsey Litchfield and Stephanie Porter on the latest episode of the ILSoyAdvisor podcast as they dive into the challenges and highlights of the 2023 growing season. They will discuss the soybean production issues faced by growers, from herbicide residuals to red crown rot, heightened insect pressure, extreme weather conditions, and more.
