| Abstract/Contents: | "This study was conducted at the Landscape Management Research Center, University Park, PA, on perennial ryegrass, maintained under home lawn/golf course fairway management conditions. The experimental area was fertilized on 6 Jun with 1.0 lb nitrogen (Scotts 36-3-7) and 30 Jun with 1.0 lb nitrogen (urea 46-0-0) per 1000 sq ft. Daconil 2787 at 6 fl oz per 1000 sq ft and Lesco Benomyl at 2 oz per 1000 sq ft were applied 17 and 30 Jun, respectively, to control brown patch in the experimental area. Individual treatment plots, 3 ft x 7 ft, were arranged in a randomized complete block design with three replications. Treatments were applied on 5 Jul with a CO²-powered boom sprayer, using TeeJet 8004 nozzles, at 35 psi, in water equivalent to 2 gal per 1000 sq ft. The experimental area was inoculated on 8 Jul with a 4-isolate pool of Pythium aphanidermatum. Following inoculation, the area was enclosed in a 30 ft x 50 ft polyethylene greenhouse to minimize radiational cooling at night. The greenhouse was vented during daylight hours, and closed at night. An internal intermittent misting system provided continuous high relative humidity. Percent of individual plot areas blighted was assessed on 19 Jul (14 days post-treatment). Data obtained were subjected to analysis of variance and Duncan's Multiple Range test. Intense disease pressure is provided by the conditions under which this test was conducted. Under these extreme conditions, excellent Pythium blight suppression was obtained with Subdue and the reduced-rate, three component mixture of ICIA5504, Aliette, and Banol." Data is presented in table format including treatment, formulation, rate per 1000 sq ft and mean disease severity. |
