 We are seeing a few spots in the fields that are already closed rows. And then we always see this Cercospora leaf spot first in the south, and then gradually we see more in the northern part of the valley. If you're following Dr. Wyatt's lab results from USDA RS in Fargo, we know that there are more and more samples of positive for Cercospora DNA in the leaf tissues. What's the best way to manage Cercospora leaf spot?
