How Herbicide Resistant Weeds Spread
Getting Rid of Weeds (GROW) explains how herbicide resistant weeds spread and how to prevent the introduction of these weeds in your fields.
2025 Input Planning: Weed Control
IL Soy Envoy Eric Beckett, CCA, recommends growers evaluate their 2024 weed control and offers information for 2025 on application timing, soybean variety field tolerance, and the effectiveness of pre-emerge herbicide residuals.
Time to Assess Your Weed Control Successes and Shortcomings
As harvest approaches, it's an ideal time to evaluate this year’s weed control efforts. Soy Envoy Karen Corrigan explains how to identify weed escapes and offers guidance on the next steps for better weed management.
Is It Worth a Rescue Treatment of Liberty Herbicide in Liberty Tolerant Soybeans to Control Waterhemp?
Soy Envoy Eric Beckett, CCA, advises farmers to consider some key questions before using a rescue treatment of Liberty herbicide to control waterhemp.
Research Update: Documenting the Extent of Resistance to Group 15 Herbicides in Illinois Waterhemp Population
Travis Wilke shares an update on an Illinois Soybean Association-funded project documenting waterhemp resistance to Group 15 herbicides, noting progress in seed testing, a new discriminating dose, and summer screening plans.
Research Update: Injury Potential to Very Early Planted Soybean from Various Soil-Residual Herbicides and Active Ingredients
Logan Miller, a Research Specialist at the University of Illinois, is collaborating with Dr. Aaron Hager on Illinois Soybean Association-funded research to evaluate the injury potential to early planted soybeans from various soil-residual herbicides. He provides an update on the study, detailing the 2024 planting dates, pre-emergence and post-emergence herbicide applications, along with photos to show the progress.
Should You Apply a Fungicide?
Halfway through the growing season, many farmers are debating fungicide application despite low commodity prices. What do our IL Soy Envoys and Certified Crop Advisers think? Tune in for their latest crop updates, Hurricane Beryl rainfall reports, Illinois record crop predictions, and more!
Weed Management in Double Crop Soybeans
Double the crop, half the weed control – that’s part of the allure of following wheat harvest with a second planting of soybeans. However, this approach involves different weed spectrums, residual herbicide timing decisions, and spray cut-off dates to consider.
Understanding Surfactants: A Key Partner for Effective Weed Control
Herbicides require specific surfactants to achieve optimal performance. Why does this matter? In this blog, IL Soy Envoy Karen Corrigan explains how the right surfactant can enhance an herbicide's effectiveness in controlling targeted weeds. Using the correct surfactant can prevent many herbicide failures.
Understanding the Crop Injury Risks of PRE Herbicides in Early-Planted Soybeans
As farmers continue to plant soybeans earlier, there are concerns about preemergence (PRE) herbicide injury to emerging seedlings. Supported by the Illinois Soybean Association, the University of Illinois Crop Sciences department is evaluating different PRE herbicides on early-planted soybeans to give farmers access to crop injury ratings for better weed management decisions.
