Which practice helps manage pink snow mold?

• A. Avoiding the use of fast-release nitrogen in late fall
• B. Applying high-rate nitrogen in late fall
• C. Mowing at minimum height in winter
• D. Frequent heavy irrigation in fall

Answer: (A)

Pink snow mold thrives in cool, moist conditions under snow, especially on turf that has become lush from late-fall growth. The key to reducing this disease is preventing conditions that favor rapid, tender growth going into winter. Using fast-release nitrogen late in the fall promotes lush turf that provides a rich food source for the fungus once snow covers the grass, increasing disease risk. By avoiding fast-release nitrogen in late fall, you keep the turf less vigorous and less conducive to the pathogen, which helps curb pink snow mold. In contrast, applying a high rate of nitrogen late fall would do the opposite by encouraging more susceptible growth. Mowing at a very low height in winter can stress the turf and doesn’t address the moisture and growth conditions that pink snow mold needs. Frequent heavy irrigation in fall maintains wet leaf tissue and soil moisture under snow, which also favors the disease.
