Here are a few pictures from the 8th Fairway on Greywalls last week before I sprayed them.

Those pink fragments are the fruiting bodies of Pink Snow Mold (Microdochium nivale).  Unlike Grey Snow Mold, which is only active under prolonged snow cover, Pink Snow Mold is active under moist conditions when the temperatures are 30-60 degrees.  

This pathogen gets started early and it is this initial growth that I target with my fall fungicide applications.
