What began as a curious anomaly spotted across Indiana and beyond has sparked national interest among farmers and agronomists alike.

Dr. Quinn shares insights from his research and field observations, including possible environmental triggers, hybrid variability, and pollination impacts. The conversation explores how sudden weather swings, from cool, moist conditions to extreme heat, may be behind this rare occurrence—and why it’s so important to stay patient before drawing conclusions about crop health and yield.

"If you have corn that you’re counting on for bushels, you need to be pretty proactive about managing southern rust," says Jacob. "The thing that keeps sticking in my mind is just how early it was here and how much heat there has been to build up an inoculum load across it. You don’t see the rust pustules the day it lands on the plant. What you’re seeing is at the tail end of the life cycle. I would assume that everything you’re looking at has more infection than what you can see visually… it can be quite severe."

If you're looking to do another fungicide application to control Southern Rust, Jacob and Joern recommend finding a product with an SDHI fungicide.

The conversation also covers late-season corn and soybean scouting priorities, from tar spot and northern corn leaf blight to SDS, white mold, and insect pressure.

🌽 From tar spot and southern rust in corn to white mold and red crown rot in soybeans, Dr. Telenko shares critical scouting tips, fungicide timing strategies, and insights on using the Crop Protection Network’s tools to make smart in-season decisions. As July heats up, she breaks down what to monitor in the field—and when to act.

🔍 Topics include:

• Current tar spot activity and risk across Indiana
• Southern rust tracking and sample submission
• Fungicide ROI and application timing at tassel and R1
• Managing gray leaf spot, frog eye leaf spot, and white mold
• How to identify and respond to red crown rot in soybeans
• Using digital tools like the Crop Protection Network to plan ahead
