Please see below and help us quantify recent rainfall and flooding impacts on crops.
🚨🚨 Calling all Indiana Farmers, Consultants, and Advisors. Please help us out and take a minute to fill out this short survey to help quantify recent rainfall and flooding impacts on crops in the state. Please share also.

Many diseases survive in crop residue like tar spot, northern corn leaf blight, red crown rot, sudden death syndrome, and Fusarium head blight.
Knowing the risks for your field can help inform future management decisions, like choosing disease-resistant hybrids or varieties for next season.

A pathologist team is conducting high intensity fungicide and biological fungicide efficacy trials in 7 states through North Central Soybean Research Program funding. Decision and ROI tools will help farmers with fungicide applications. #SoyCheckoff bit.ly/4jTgREd

Ear rot issues during #harvest26?
It's critical to ID ear rots in field as many of the fungi responsible for ear rots produce mycotoxins, which can harm livestock and humans. Grain contaminated with mycotoxins can be difficult to market and may be docked in price.

Fusarium stalk rot causes shredded pith that may be tan to light pink. Brown streaks may be observed on the lower internodes.
The fungi overwinter in corn residue, other dead plant residue, and in corn seed.
Resistance to Fusarium stalk rot is available. Rotation and tillage will reduce inoculum.

Some ugly stalk rots starting to show up in areas of Indiana. Something to watch out for this fall. Best thing to do is prioritize the fields that have it and get the corn out of the field asap.

Corn stalk rots cost farmers $4.2 billion in the past five years.
Test stalk integrity using the pinch test. Prioritize harvest for a field if 10%+ stalks are rotted.

There are five major mycotoxins associated with ear rots. Toxic effects vary by type, concentration, exposure, and animal species.
If a field has kernel or ear rot problems (10%+ of ears are moldy), test for mycotoxins.

Was able to spend last week traveling East-Central Indiana with @DTelenko and @PurdueSoybean. Very eye opening and disheartening to see the impacts from the early August storms and flooding on the crops in this area of the state.
