| Abstract/Contents: | "The experiment was conducted at the Valentine Turfgrass Research Center, University Park, PA, on a sward of creeping bentgrass maintained under golf course fairway management conditions. The turfgrass was mowed three times per week at 0.5-in. cutting height. The soil was a Hagerstown silt loam with pH 6.8. The experiment was fertilized 19 Apr with 1.0 lb nitrogen (18-9-18) per 1000 sq ft, and on 1 Jun with 0.25 lb nitrogen (46-0-0) per 1000 sq ft. Bensumec 4F was applied on 12 May at a rate of 2 gal/A for pre-emergent control of crabgrass. Trimec Bentgrass Formula was applied on 17 May (0.7 fl oz per 1000 sq ft) for control of broadleaf weeds. Mach 2 2SC (1.5 fl oz per 1000 sq ft) was applied 7 Jul for control of black cutworms. Treatment plots, 3 ft x 6 ft, were arranged in a randomized complete block design with three replications. Treatments were applied with a CO2-powered sprayer, using a TeeJet 11008E nozzle at 40 psi, in water equivalent to 2 gal per 1000 sq ft. Applications were made on 7 and 21 Jun, and 5 and 19 Jul, unless otherwise noted in the table. Disease incidence was evaluated weekly and data were subjected to analysis of variance and multiple comparisons of the mean values were made using the Waller- Duncan k-ratio test. Data from 26 Jul, and 3 and 10 Aug are presented. Dollar spot incidence was moderate in June and became increasingly severe during July and early August. On 10 Aug 15 treatments were providing excellent control of dollar spot, while 3336 Plus treatments applied at 3.0 or 4.0 fl oz were not significantly different from the untreated check. Complete suppression of dollar spot was achieved throughout the study with the Emerald + Curalan tank mixture, the Emerald + urea mixture, and the two 0.13 oz (14-day interval) Emerald treatments. No phytotoxicity was observed in the experiment." |
