Abstract/Contents:"This study was conducted at Riverside Country Club, Bozeman, MT, on a predominantly annual bluegrass fairway maintained at a 0.5 inch height of cut. A total of 2.25 lbs nitrogen per 1000 sq ft was applied to the fairway in 1997 with the last application made on 29 Oct 97. All treatments were applied preventively 21 Oct 97. Split applications were applied on 21 Oct 97 and 24 Nov 97. Plots were 6 ft x 9 ft and arranged in a randomized complete block design with three applications. Treatments were applied with a CO₂-powered boom sprayer operating at 30 psi in water equivalent to 2 gal per 1000 sq ft. Permanent snow cover lasted from 25 Nov 97 through 31 Mar 98. Snow mold was evaluated on 1 Apr 98. Data were subjected to analysis of variance and LSD test. Snow mold pressure was severe and uniform throughout the experimental area with approximately 70% Fusarium patch (pink snow mold) and 30% Typhula blight (gray snow mold). Several treatments tested provided excellent control of snow mold. The PCNB fungicides in combination with other products performed extremely well, as did the experimentals FL971556 and FL971557. Some phytotoxicity was noted on 24 Nov 97. All products containing PCNB and the experimentals FL971556 and FL971557 resulted in discoloration of the turf. The phytotoxicity may have been compounded by the fact that November was a sunny, dry month. Minor discoloration was still observable on 1 Apr 98."
