# Why Does Fescue Grass Turn Brown in Summer?
-
Identification
-
Southern blight is a fungal disease of fescue caused by Sclerotium rolfsii. The fungi are most active in temperatures of 85 to 95 degrees F. Fescue lawns with heavy thatch buildup are more susceptible to fungal growth.
Damage
-
The disease is characterized by the appearance of semi-circular to circular, brown areas on lawns. Infected grass gradually changes to a reddish-brown shade and dies. With disease progression there is appearance of white, threadlike growth or mycelia on grass blades. Hardened fungal bodies resembling mustard seeds, referred to as sclerotia, appear on blades near the soil line.
Management
-
Keep grass in vigorous health with proper irrigation and fertilization. Avoid buildup of thatch to minimize chances of disease. Do not overwater grass. Fungicidal control options include the use of azoxystrobin, flutolanil and triadimefon.
