| Abstract/Contents: | "This evaluation was conducted at Giants Ridge Golf Resort in Biwabik, MN on a creeping bentgrass fairway maintained at a height of 0.5-in. Individual plots measured 3 ft ^D#x 10 ft, and were arranged in a randomized complete block design with four replications. Individual treatments were applied at a nozzle pressure of 40 psi using a CO2-pressurized boom sprayer equipped with two XR Teejet 8004 VS nozzles. All fungicide solutions were agitated by hand and applied in the equivalent of 2 gallons of water per 1,000 ft2. Two applications were made in the fall of 2007, the early treatments were applied on 22 Oct and late treatments were applied on 16 Nov. Natural infection was allowed to occur, and there was continuous snow cover on the plots from 1 Dec until early April, a total of approximately 120 days. A week long break in snow cover in early April was followed by several feet of snow that melted in late April. Disease severity and color were recorded on 30 Apr 08. Data obtained were subjected to analysis of variance and means were separated using the Student- Newman-Keuls test (α = 0.05 for both tests). The predominant snow mold species observed in the experimental area was T. ishikariensis, though minor amounts of T. Incarnate and M. Nivale were also observed. Disease severity was moderate to severe with untreated controls averaging 76% disease. Despite this pressure, all treatments provided excellent to moderate control when compared to the untreated control. Most of the treatments that provided excellent snow mold control included three active ingredients applied at high label rates, although a couple treatments with two active ingredients also performed well. Treatments that provided complete control of all snow molds in the experimental area were Spectro + 26/36 + CLEX-9, Spectro + CLEX-9, Insignia + Trinity + Turfcide 400, Tartan + Turfcide 400, and Reserve + Compass. A significant, yet still acceptable reduction in turfgrass color was observed with Turfcide 400 (PCNB) applied at 10 fl oz. Treatments that included Turfcide 400 at 6 fl oz did not exhibit any reduction in turfgrass color." |
