It's really difficult to diagnose lawn problems without knowing the cultural care they're getting, but here's my best guess: Brown Patch Brown Patch is most common to Bermuda, Kentucky Bluegrass, Centipede Grass, Bent Grass, St. Augustine, and ryegrasses in regions with high humidity andor shade. Brown patch commonly starts as a small spot and can quickly spread outwards in a circular or horseshoe pattern up to a couple of feet wide. Often times, while expanding outwards, the inside of the circle will recover, leaving the brown areas resembling a smoke-ring. The best prevention for brown patch is to aerate often, reduce shade to affected areas, and follow a fertilization schedule. The most common fungicides used on Brown Patch are: benomyl or chlorothalonil. Be sure to apply according to label directions. Good luck with your lawn!
