Pythium blight, also known as cottony blight or grease spot, is a devastating disease that may occur on any susceptible turfgrass, regardless of age, when weather conditions favor disease. It occurs in Alabama on overseeded and established stands of certain coolseason turfgrasses—most often on perennial ryegrass overseeded alone or in mixtures with bentgrass, fine fescue, and rough stalk bluegrass (Poa trivialis). Established bentgrass greens and tees are often badly damaged by Pythium blight. Lush turf receiving large amounts of nitrogen fertilizers, particularly those in low-lying or wet, poorly drained soils, are the prime targets of the fungi causing Pythium blight. This four-page publication provides information on causal fungi, disease detection, disease cycle, and disease control. Includes photos for identifying pythium blight and tables of recommended fungicides and formulations.
