Brown Patch Lawn Fungus
Brown patch is a summer disease that is most common on tall fescue but can occur on all turf grasses. It is caused by the fungus Rhizoctonia solani. The symptoms sometimes occur as discrete circular patches ranging from a few inches to several feet in diameter. Brown patch develops rapidly when night temperatures exceed 70 degrees and duration of leaf wetness exceeds 10 hours. Brown patch can be severe following extended periods of hot (70-90degrees), rainy, humid weather.
Summer Patch Lawn Fungus
Summer patch sometimes referred to as frogeye patch is a destructive disease commonly found in bluegrass. It develops initially June through August as small patches of turf, 2 to 6 inches in diameter. Grass blades in the patch change to a dull reddish brown, then tan and finally a light straw color. In the final stages of the disease, circular patches of dead grass form throughout the turf area. Healthy grass often occurs at the center of the patch, resulting in a characteristic frogeye pattern. Circular patch symptoms develop because the fungus grows radially from acentral infection point. When weather conditions are ideal for disease development, affected areas may overlap resulting in large areas of affected turf.
