There are several types of snow mold related diseases that can cause significant damage on golf course turf. These diseases can occur under snow or on open ground. I won't get into the specifics of the diseases but due to their potential severity, we take precautions by applying a fall application of fungicide to help prevent the occurance of these threats.
The snow molds develop for a variety of reasons but mostly due to the combination of humidity, wetness, temperature ranges, and extended periods of snow coverage.
