Snow Mold Treatments Have
Been Effective This Year February 29, 2016 By Blake Meentemeyer, agronomist, West Region

This fairway turf was protected by a preventative fungicide application. The adjacent rough was not treated and snow mold developed.  

Snow mold can be a real problem when ice and snow remain on turfgrass playing surfaces for several months. Typhula snow molds are less likely to occur when a preventive fungicide is applied before the onset of winter. If snow mold has developed in untreated areas, like the rough shown on the right side of this photograph, it will take longer to recover and become playable than treated areas.

Although weather conditions and the duration of snow cover will dictate effectiveness, is it possible to have One snow mold fungicide to rule them all? In most cases, a combination of fungicide active ingredients will offer the best snow mold control. Nevertheless, if snow cover persists and freeze/thaw cycles are frequent, even the strongest fungicide program will break down over time and disease symptoms may appear. Fortunately, most of the snow has melted in the West Region and golf courses are looking fabulous.
