In this episode of the Indiana Pioneer Agronomy Podcast, Ben Jacob and Carl Joern dig into an unusual outbreak of southern rust across Indiana, Illinois, and even into the northern Corn Belt. They share how to identify the disease, why its arrival this year is out of the ordinary, and strategies for fungicide timing to protect yield and standability.

Description

"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.About Southern Rust - https://www.corteva.us/Resources/crop-protection/disease-mgmt/watch-for-southern-rust-in-corn.htmlSouthern Rust in Corn - https://www.pioneer.com/us/agronomy/southern_rust_cropfocus.html Hosted by Simplecast, an AdsWizz company.
