Staging Soybeans for Fungicide at the R3 Growth Stage
When scouting soybeans for fungicide application, it's important to first check the growth stage across the field. Stephanie Porter, CCA, demonstrates how to identify the R3 growth stage in soybean plants and how to inspect for diseases such as Septoria brown spot and insect damage.

Researchers are on the lookout for Red Crown Rot (RCR) across Illinois. If you suspect RCR in your fields, send your diseased samples to the USDA-ARS lab in Urbana for free. Help us monitor and identify new areas in Illinois where this pathogen has spread.
And the Bad News Is?
After a week's break, the IL Soy Envoys have returned to provide their latest field reports. They cover precipitation levels—or the lack thereof in some regions—and discuss the emergence of tar spot and other potential diseases.
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.
IL Crop Conditions Getting Worse?
On the latest episode of the ILSoyAdvisor podcast, the Soy Envoys discuss Illinois crop conditions, emergence issues, "floppy corn," ongoing weed scouting, and pest concerns such as slugs, Japanese beetles, and stinkbugs.
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.
Monitoring Root Development and Planning for Fungicide
Crop conditions across the state remain highly variable, and the IL Soy Envoys share their regional updates. This episode also covers wheat harvest, root establishment issues, slug damage, crops in the "ugly duckling" phase, herbicide misapplications, and notes for fungicide season.
Post Dicamba June 12th Cutoff & 85 Degree Temperature Reminder
The application cutoff date for dicamba use over-the-top of soybeans is June 12th, and the projected forecast for much of the state shows elevated temperatures for the week. IFCA understands the pressure ag retailer members face to control weeds with available crop protection products, but violations of the cut-off date, temperature restriction, or recordkeeping requirements will be considered willful violations of the Illinois Pesticide Act, so it is crucial to discuss label requirements with customers to ensure compliance.
