Abstract/Contents:"Eight fungicide treatments were evaluated on Touchdown Kentucky bluegrass for control of stem rust, dollar spot, and Drechslera leaf spot. The turf was established Sep 1992 at the University of Nebraska John Seaton Anderson Turfgrass and Ornamental Research Facility at Mead, NE...Fungicide treatments were initiated 30 Jun and repeated at two or four week intervals until 25 Aug. Four replications of 5 ft x 5 ft plots were arranged in a randomized complete block design...Dollar spot and Drechslera leaf spot developed rapidly in Jul and Aug. Stem rust was not detected until late Aug; it then developed rapidly becoming severe by early Oct. All treatments effectively controlled rust for at least 30 days after the last application. No rust was found on the Banner 1.1E, Daconil 2787F, Bayleton 25DF, and Eagle 40W treatments. Only a trace of rust was found on the ASC-67098-Z-treated plots. Control of dollar spot and Drechslera leaf spot was erratic in the 14 Jul evaluation, but in the 8 Aug evaluation all treatments except for Fluazinam 500 F at 0.5 fl oz significantly controlled these diseases. Fluazinam 500F at 1.0 fl oz gave good disease control indicating that 0.5 fl oz rate is too low. No phytotoxicity was observed."
