Abstract/Contents:"This evaluation was conducted at the OJ Noer Turfgrass Research and Education Facility in Verona, WI on a colonial bentgrass fairway maintained at 0.5-in. grown on a native silt loam soil. 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 gal water per 1,000 ft2. All treatments were initiated 13 Jun, and subsequent applications were made at 14, 21 or 28 day intervals. Plots were inoculated with R. solani-infested rye grain on 20 Jul and were irrigated at 150% of estimated evapotranspiration. Brown patch severity (%) and turf quality (1 to 9, 9 being excellent and 6 acceptable) were visually assessed and subjected to an analysis of variance and means were separated using the Waller-Duncan test. Brown patch was slow to develop in 2011, yet by late summer disease pressure was high. All treatments reduced brown patch severity compared to the non-treated control on all rating dates. Most treatments performed exceptionally well on the 10 and 24 Aug rating dates, although treatments containing Velista, Eagle, and Curalan still had limited brown patch development. Turfgrass quality ratings mirrored brown patch severity, with the highest quality generally provided by those treatments containing a QoI fungicide (Heritage, Honor, Insignia SC, Renown). No phytotoxicity was observed with any product."
