Grey snow Mould
Causal Agent: Typhula Incarnata and Typhula Ishikariensis
Hosts: All turf grasses in Canada
Epidemiology: Both Grey and Speckled snow moulds require snow cover to cause disease. Grey Snow mould requires 60 days of continuous snow cover while Speckled snow mould requires at least 90.
Target: Foliage (in extreme conditions entire plants can be affected)
Evidence: Circular areas of light yellow, straw-coloured or grayish brown turf from 3cm – 1m become apparent at snowmelt. Leaves can be matted together with white to gray mycelium.
Clues: On infected leaves, reddish brown sclerotia (spherical in shape) are an indication of Grey Snow Mould whereas black sclerotia is an indication of Speckled snow mould.
