On warm season turf grasses, the disease is characterized by at least two different types of symptoms.

The leaves can be easily pulled from the stolons with the smoke ring because the fungus destroys the tissue at the base of the leaf. Symptoms first appear as small circular patches of water soaked, dark grass that soon wilt and turn light brown. Stolons often remain green as the disease develops, the circular patches enlarge, smoke rings become apparent and new green leaves may emerge in the center of the circular areas. Control. When environmental conditions are favorable, brown patch is likely to develop on susceptible turf grasses. The severity of the disease can be somewhat controlled by following a strict fertilization schedule that only apply the proper amount of nitrogen and trace elements during the ideal times by watering early in the morning to remove dew and all the grass to dry quickly mow grass a little taller with a sharp mower blade, and when possible, by bagging the lawn clippings during likely periods of disease activity. Fungicide applications are most effective when used as a preventative before the disease has become established in the lawn. Since brown patch typically only kills the leaf, lawns attacked by brown patch will usually return when conditions improve as long as secondary problems do not take advantage of the turfgrass in its weakened state. Prevention. The best prevention for brown patch is to aerate often, reduce shade to effected areas, and follow a fertilization schedule to help prevent fertilization with excess amounts of nitrogen.
