Abstract/Contents: | "This evaluation was conducted at the Landscape Management Research Center, University Park, PA, on Kentucky bluegrass maintained under home lawn/golf course fairway management conditions. Urea (46-0-0) was applied to the experimental area at 1.0 lb nitrogen per 1000 sq ft on 3 Apr. On 8 May, Dimension 1EC was applied for control of crabgrass, and on 14 May, Turflon II was applied for control of broadleaf weeds. Individual plots, 3 ft x 15 ft, were arranged in a randomized complete block design with three replications. Fungicides were applied with a CO²-powered boom sprayer, using TeeJet 8004 nozzles, at 40 psi, in water equivalent to 2 gal per 1000 sq ft. Applications were made on 18 Apr and 2, 16, and 30 May, except as noted in the table. Treatments were visually evaluated on 15 and 30 May. Data were subjected to annalysis of variance and Waller-Duncan k=100 test. Disease pressure was moderate to heavy in the experimental area. Disease severity was unaffected by nitrogen application, regardless of source or application rate in this experiment. Excellent leaf spot suppression was provided by all rates of Heritage; the dicarboximide fungicides Chipco 26019, Vorlan, and Curalan; and the contact fungicides Fore and Daconil Zn." |
