Virginia Cotton: Leaf Scorch – One Thing To Minimize It

Since it is sort of wet to get any equipment in the field, this is a good time to do some field walking. One of the observations I have been making is related to leaf scorch and some symptoms associated with herbicide application.

More scorch almost always will develop with high moisture and humidity and heat compared to lower humidity, mild temperatures and dry soil. We cannot change the environment, of course.

The part we can change is how many ingredients we add to the tank mix. When conditions favor scorching, the more things we add, then the more symptoms we can see. The good news it is that the conditions that favor scorch also favor recovery

As long as these sprays occur prior to squaring, then the yield is not affected.
