Back to Top Down here in south Arkansas, we have a real problem with St. Augustine grass. We can t seem to prevent brown patch. In my particular case, even a professional lawn care company using a professional Daconil fungicide cannot stop or even control it. Right now, brown patch has spread all over the yard. I see the same thing happening in yards all over town.
Brown patch can be a very difficult problem to control.
It is not an easy product to locate, but can be special-ordered. Since it is packaged for the professional lawn care companies, I would ask your lawn care service to find it and spray for you. Next spring when your grass begins greening up, begin spraying. Spray two or three times at 10 -14 day intervals and see what happens after that. When fertilizing, use a slow-release nitrogen fertilizer, or put out frequent small amounts of fertilizer.
