Abstract/Contents:"An evaluation of fungicide treatments for control of spring leaf spot/melting out (Drechslera poae) was conducted at the Landscape Management Research Center, University Park, PA, on Kentucky bluegrass (Poa pratensis 'S-21') maintained under home lawn/golf course fairway management conditions. Urea (46-0-0) was applied at 1.0 and 0.8 lb actual N per 1000 sq ft on 3 and 23 Apr, respectively. Individual plots, 3 ft x 20 ft, were arranged in a randomized complete block design with three replications. Fungicides were applied with a CO2-powered boom sprayer using T-jet 8004 nozzles, at 30 psi, in water equivalent to 2 gal per 1000 sq ft. Applications were made on 16 Apr, and 1, 15, and 29 May, except as noted in the table. Treatments were visually evaluated on 12 June. Data obtained were subjected to analysis of variance and Duncan's Multiple Range test. Throughout the trial, excellent leaf spot control was obtained with the dicarboximide fungicides, Chipco 26019, Curalan, Ronilan, and Vorlan. CGA-163935 produced severe phytotoxicity expressed as thinning, stunting, and dark-greening of foliage."
