Cotton Leaf Disease in Southwest Georgia

Posted by romeethredge on July 27, 2012

Cotton leaf disease is here and some of it is the Corenespora Target Spot, there is some Stemphyllium as well. The Corynespora is not caused by a lack of Potassium in the plant like the Stemphyllium is. Corynespora usually begins in the bottom of the canopy and may respond to fungicide treatments when applied early enough.  It is worse when we have lots of leaf wetness and worse where cotton follows cotton.  Also some cotton varieties seem to get it worse.

Here’s a photo I took of some yesterday.
