Snow mold is a cold-weather fungus that primarily damages or kills cool-season grasses. The signs of snow mold aren’t noticeable until the snow starts melting. The damage is usually concentrated in circles of 3-12 inches in diameter.
Snow mold is a fungal disease caused by a pathogenic fungus. It stays dormant in the soil until the conditions are just right to invade nearby grasses. When the snow melts, it creates a cool and incredibly humid environment that is appropriate for the growth of snow mold. Once the snow is finally thawed, a lawn infected with snow mold – straw-colored patches, rings or matted areas can be seen. Snow mold heavily affects leaves rather than crowns of your turf grass.
The snow mold is of two types:
Gray snow mold – Gray snow mold is the less damaging form of snow mold. It typically damages blades of the grass. Gray snow mold can survive throughout hot summer months as sclerotia under the ground or in plant debris.
Pink snow mold – Pink snow mold (Microdochium nivale or Fusarium patch) is the severe form of snow mold. It can cause more damage than gray snow mold, destroy the roots and crowns of grass. It can survive the summer months in decayed plant debris as spores or mycelium.
Signs of snow mold are noticeable in the spring when the snow begins to melt. They usually appear in the straw-colored circular patches. The grass in these straw-colored patches is usually matted down and crusty. The patches are grayish-white in color if they are caused by gray snow mold and whitish-pink if caused by pink snow mold.
Pink snow mold is more harmful than gray snow mold, as it can kill the crown and roots of grass plants. Gray snow mold usually affects the grass blades.
