What are common symptoms of Pink snow mold in turf?

Pink snow mold, caused by the fungus Microdochium nivale, presents distinct symptoms in turfgrass that can help diagnose its presence. One of the most notable characteristics of this disease is the formation of circular patches that typically range from 2 to 6 inches in diameter. These patches often have a slightly matted appearance and can be pink or white, depending on the environmental conditions and the stage of the disease.

The circular shape of the patches is a key identifying feature, as they can expand and merge into larger areas if left untreated. This symptom helps differentiates it from other turf diseases that might present irregular patch shapes or different color variations. Recognizing this symptom is crucial for effective management and control measures when dealing with turf diseases, especially in cool, moist environments where pink snow mold is prevalent.

Understanding this symptom allows turf managers and lawn care professionals to take timely actions, such as improving air circulation, adjusting irrigation practices, and applying appropriate fungicides when necessary.
