| Abstract/Contents: | "This evaluation was conducted at Wawonowin Country Club in Champion, MI 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 02 Oct 08 and late treatments were applied on 28 Oct 08. Natural infection was allowed to occur, and there was continuous snow cover on the plots from mid- November to mid-April, a total of approximately 150 days. Disease severity and color were recorded on 28 Apr 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 extremely high at this site this year with untreated controls averaging 96.3% disease. Although all three major snow mold diseases were observed, the dominant pathogen causing damage was Typhula ishikariensis. The pressure was so extreme that most treatments failed to provide significant reductions in disease severity compared to the untreated controls. Despite the high pressure, EXP-1 6.0 fl oz + Triton Flo, 26/36 + EXP-7, 26/36 + Endorse + EXP-7 provided complete control of all snow molds. Tourney + 3336, EXP-1 4.0 fl oz + Triton Flo, EXP-1 5.0 fl oz + Triton Flo, Triton Flo + Compass + Daconil Ultrex, Reserve + Compass, QP TM/C (Early) + QP Ipro + QP Propiconazole (Late), and QP TM/C + QP Ipro + QP Propiconazole provided acceptable protection (<5% disease). Differences in plot color were also observed, though rating color was difficult on plots that were severely infected. Treatments containing EXP-1 and Triton Flo had a statistically significant greener color compared to untreated areas. All three of these treatments contained Bayer StressGuard® technology in addition to the active ingredient. No significant discoloration was observed with any treatments at this site." |
