| Abstract/Contents: | "The experiment was conducted at the Landscape Management Research Center, University Park, PA, on Kentucky bluegrass maintained under golf course fairway management conditions, mowed three times per week at a cutting height of 1.0 inch. The soil was Hagerstown silt loam with a pH of 6.9. Urea (46-0-0) was applied to the experimental area at 1.0 lb nitrogen per 1000 sq ft on 8 and 28 Apr. On 2 May Dimension 1EC was applied to the experimental area at the rate of 1.0 fl oz per 1000 sq ft for control of crabgrass. Treatment plots, 3 ft x 9 ft, were arranged in a randomized complete block design with four 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 7 and 21 May, and 4 Jun, except as noted in the table. Treatments were visually evaluated on 27 May. Data were subjected to analysis of variance, and the mean values were separated using Duncan's New Mutiple Range Test (P=0.05). The weather was cool and dry during the study period, and disease severity was low throughout the experimental area. Chipco 26GT, Heritage, three chlorothanil treatments (Daconil Ultrex, Daconil Zn, and Echo), and Fore were significantly different from the untreated check under the conditions of this experiment." |
