| Abstract/Contents: | " This evaluation was conducted at Sentryworld Golf Course in Stevens Point, WI on a creeping bentgrass fairway maintained at a height of 0.5 in. Individual plots measured 3 ft 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 fungicides were agitated by hand and applied in the equivalent of 2.0 gallons of water per 1,000 ft2. Applications were made in the fall of 2010; the early treatments were applied on 19 Oct 10; and the late treatments were applied on 23 Nov 10. The experimental area was not inoculated, and there was continuous snow cover on the plots from early December of 2010 to mid-April of 2011, a total of approximately 120 days. Disease severity and turfgrass quality were recorded on 10 Apr 11. Disease severity was visually rated as percent disease and turfgrass quality was visually rated on a 1 to 9 scale with 6 being acceptable. Data were subjected to an analysis of variance and means separated using the Waller-Duncan test. Although Typhula incarnate and Microdochium nivale were observed in the experimental area, the primary pathogen observed was T. ishikariensis. Disease pressure was high as non-treated controls averaged 74.8% disease. Despite this high pressure, numerous treatments provided acceptable levels of disease control (< 5% disease). Treatments containing three or more active ingredients were generally the most effective at providing acceptable suppression, including ten treatments that provided complete snow mold control. Treatments containing one or two active ingredients generally did not adequately suppress snow mold development. Two exceptions were Torque + Affirm and Concert, which both provided excellent snow mold suppression. Differences in turfgrass quality were also observed, though most products that provided acceptable disease control provided similar turfgrass quality. No phytotoxicity was observed with any product." |
