Abstract/Contents:"This evaluation was conducted on a fairway at Pine Hills Country Club in Sheboygan, WI on a mixed stand of creeping bentgrass [80%] and annual bluegrass (Poa annua) [20%] stand maintained at 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 Teejet AI8004 VS nozzles. All fungicides were agitated by hand and applied in the equivalent of 2.0 gal water per 1000 ft2. All treatments were applied on 23 May and again on 12 Jun. Disease severity was assessed as a percentage of susceptible bentgrass within each plot expressing leaf spot symptoms. Turfgrass quality was visually assessed on a 1-9 scale with 1 being bare dirt, 6 being acceptable, and 9 being exceptional. Data collected were subjected to an analysis of variance and means separated using the Waller-Duncan test. Leaf spot pressure was high at Pine Hills, with non-treated controls averaging approximately 60% disease throughout the summer. Despite this high pressure, all products except for Daconil WeatherStik on 11 Jul and Daconil WeatherStik and Reserve on 1 Aug suppressed leaf spot relative to the non-treated control. Insignia SC, Banner MAXX II, and Headway all provided excellent suppression of leaf spot on both rating dates. Interestingly, neither Chipco 26GT nor Daconil WeatherStik applied alone reduced leaf spot, but when applied as a tank mixture significantly suppressed leaf spot on 1 Aug. Turf quality mirrored leaf spot severity ratings, and phytotoxicity was not observed with any treatment."
