Gray Snow Mold on Turfgrass: Typhula spp.

Winter diseases of turfgrasses are often associated with melting snow or cold, wet periods. Bluegrasses (Poa spp.), fescues (Festuca spp.), and ryegrasses (Lolium spp.) may be attacked, but bentgrasses (Agrostis spp.) are most susceptible. Two diseases, Gray Snow Mold (Typhula blight) and Pink Snow Mold, are common in New York, and may occur singly or side-by-side. Since different fungicides may be used to control each of these diseases, it is necessary to distinguish between them.
