How to Identify and Control Snow Mold

Golf course severely infected with gray snow mold, also known as Typhula blight (Typhula spp.).

When lawn disease strikes, your dreams of a thick, beautiful lawn may seem to slip out of reach. But the solution to your problems can be as simple as disease I.D. and changes in your lawn care routine. Most common lawn diseases start with fungal pathogens that can't flourish unless conditions favor their growth. With proper lawn disease identification and disease-fighting culture, you can control disease and enjoy a healthy lawn.

Snow mold is a winter-related disease that strikes grasses during cold, wet periods from mid-fall through mid spring. As its name suggests, this disease often grows under snow cover, attacking shoots and staying hidden until snow melts. Tall fescue, fine fescue, perennial ryegrass and Kentucky bluegrass often struggle with snow mold disease.1,2
