Pythium leaf blight or 'Damping Off' is a turfgrass disease caused by Pythium spp. This disease can appear suddenly during hot, humid weather and the patches of affected grass can enlarge at a rapid rate. When affected by Pythium Leaf Blight, early morning grass can appear water-soaked and in dark patches. These infected leaves become light tan to brown and shrivelled and matted when dry.
Excessive moisture is required before Pythium spp. can cause extensive damage and the disease may be more severe in alkaline soils than acidic soils.
