Revenge fungicide applications never work. Below is some data where we tried rescue treatments of fungicide for white mold management. You can't get diseases under control once they are already moving, especially white mold. Plus negative ROI! Shawn Conley

With high tar spot severity, ground-applied fungicide resulted in a partial net-return ranging from $11.9 loss to $83.9/A gain. With low tar spot severity, the partial net-return ranged from a $46.5 loss to a $5.8/A loss. Yield data and fungicide efficacy tar spot research

And we are off! Hope you are at the UW Agronomy and Soils field day. The pest management stop is at it bright and early!

I agree. Fungicides have worn off plus the weather is getting more conducive for tar spot! Checking standability in fields will be crucial for a successful harvest.

Building on this point: Mike Rankin ⚾ Damon L. Smith & I discussed foliar disease vs. frost induced dry down. Per D - disease affects plants differently than frost. Nutrient scavenging induced by disease forces plant to shut down & dry out far quicker than a frost event. In one
