| Abstract/Contents: | "This evaluation was conducted at Sentryworld Golf Course in Stevens Point, W 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 p.s.i 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 gallons of water per 1000 ft2. Two applications were made in the fall of 2008, the early treatments were applied on 21 Oct 08 and the late treatments were applied on 25 Nov 09. Natural infection was allowed to occur, and there was continuous snow cover on the plots from early December to late March, a total of approximately 100 days. Disease severity and color were recorded on 26 Mar 09. Data obtained were subjected to analysis of variance to determine significant differences (P = 0.05) between treatment means using the Student-Newman-Keuls test. Disease pressure was high at this site this year with untreated controls averaging 76.3% disease. Although all three major snow mold diseases were observed, the dominant pathogens causing damage were Typhula ishikariensis and Typhula incarnate. All treatments with the exception of 11 and 52 provided a significant reduction in disease severity compared to the untreated control. Due to the high pressure, many treatments did not provide acceptable protection (<5% disease) against T. ishikariensis. Overall, 28 treatments provided complete snow mold protection. Trinity alone and in mixtures with Daconil Ultrex and other products were in many of the treatments that provided complete control. Some other fungicides that also provided complete control when applied with one or two additional fungicides were Instrata, QP Ipro, Reserve, Tartan, Triton Flo, Tourney, and 26/36. Many other treatments provided acceptable control. Differences in plot color were also observed, with six treatments that included either Reserve, Tartan, or Triton Flo having a statistically significant greener color compared to untreated areas. All six of these treatments contained Bayer's StressGuard® technology in addition to the active ingredient. Treatments containing PCNB caused discoloration, but the discoloration was minimal and recovered quickly." |
