| Abstract/Contents: | "Evaluation of fungicides for control of brown patch, 1997: The evaluation was conducted at the Valentine Turfgrass Research Center, University Park, PA, on colonial bentgrass maintained under golf course fairway management conditions, at 0.5 inch cutting height. The soil was Hagerstown silt loam with a soil pH of 6.4. The test area was fertilized on 30 May and 15 Jun with with 1.0 lb nitrogen (Scotts 19-0-17) per 1000 sq ft, and on 11 Jul with 0.5 lb nitrogen (Scotts 19-0-17) per 1000 sq ft. Individual plots, 3 ft x 12 ft, were arranged in a randomized complete block design with three replications. Treatments 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, except as noted in the table. Applications were made on 19 Jun, and 3 and 18 Jul, except as noted in the table. Disease pressure was light to moderately heavy during the latter part of July. Brown patch was evaluated on 17 and 28 Jul. Data were subjected to analysis of variance and Duncan's New MRT, P=0.05. On the 17 Jul rating date, disease presure was light to moderate, and nearly all treatments were providing excellent brown patch suppression. By 28 Jul, disease pressure was heavy, and brown patch was present in 17 of the treatments. Throughout the experiment complete suppression of brown patch was obtained from both 0.2 oz rates of Heritage, ProStar the two Scotts combinations, the Bayleton combinations with Thalonil and Heritage, and Eminent Star." |
