Turfgrass Disease Profiles: Gray Leaf Spot (BP-107-W)

Purdue Extension Publication

Gray leaf spot is a foliar disease that affects perennial ryegrass and tall fescue. Moderate outbreaks of gray leaf spot result in clusters of thin, off-colored turf. Severe outbreaks, however, will result in the death and decay of extensive areas and ruin the entire turf stand. This publication describes the symptoms and development of this disease, and provides management options.
