Snow Mold or LTB (non-sclerotial low-temperature basidiomycete)
and SLTB (sclerotial LTB) Snow Molds (Coprinus psychromorbidus
). Large patches, occasionally with dense, white cottony
mycelial growth at edges (LTB); or small (1-3 mm) brownish-
black, irregular sclerotia on leaves and stem bases (SLTB).
Often, LTB patches do not coalesce. - shallow to deep snow
covers - slow melting of drifts in spring - unbalanced, late
nitrogenous fertilization - previous attacks - most common tuff
grass species, e.g., Flyking, Nugget, Sydsport, Merion, and
Newport Kentucky blue grasses are susceptible Control snow cover
with fences and spread snow drifts or encourage rapid melting
with soot or fine ashes. Control thatch. Tests suggest that
unbalanced phosphate applied when turf is dormant in late fall
in the Prairies will favour LTB snow mold. Dormie and Park are
more resistant than other Kentucky bl
