Abstract/Contents:"The trial was conducted on a creeping bentgrass green (Hole #4) at the Waverly Municipal Golf Course, Waverly, Iowa. This green had a history of outbreaks of gray and pink snow molds in most of the last 10 years. The experimental design was a randomized, complete-block with 4 replications. All plots measured 5 ft by 5 ft. Fungicides were applied on November 13, 1990, using a modified bicycle sprayer at 30 psi and a dilution rate of 5 gal/1000 ft2. Immediately after application of fungicides, the entire plot was covered with two layers of Curlex High-Velocity excelsior mats (American Excelsior Co., St. Paul, MN). The mats were fixed in place with wire stakes. The purpose of the mats was to simulate snow cover and provide favorable conditions for the development of snow mold even in the absence of snow cover (W. Stienstra, Department of Plant Pathology, University of Minnesota, personal communication). Snow cover persisted on the green from December 5, 1990, until March 1, 1991. Mats were removed on March 6. On that date, symptoms of gray and pink snow mold were abundant at many sites on the golf course. Snow-mold development on untreated check plots was moderate (Table 23). Symptoms of both gray and pink snow mold were evident in these plots. All fungicide treatments were free of snow mold damage. None of the fungicide treatments were significantly different from the others in disease suppression. Treatments that incorporated green paint were perceptibly greener in color than other treatments. No phytotoxicity symptoms were observed. Because snow-mold occurred naturally at Waverly Municipal Golf Course in 1990-91, no conclusion could be drawn about the effect of excelsior mats on disease development. However, in winters with less than 3 months of snow cover (a common occurrence in Iowa), the mats may provide temperature and moisture conditions favorable for snow mold development."
