| Abstract/Contents: | "The test was conducted on a sand-based green located at the University of Kentucky Turf Research Center near Lexington. The turf was maintained at a 0.188-in. mowing height, and fertilized with urea (46-0-0) at the rate of 1.5 lb N/1000 sq ft on 28 Sep 07 and on 14 Oct 07, and 1 lb N/1000 sq ft on 15 Jul 08 to promote brown patch development. Irrigation was applied twice daily to promote brown patch development beginning 7 Jul. Plots measured 3 ft x 3 ft with 1.5-ft borders, and were arranged in a randomized complete block design with three replications. Fungicide sprays were applied using a CO2-pressurized hand-held sprayer fitted with Spraying Systems 8003E flat-fan nozzles delivering 1.5 gal/1000 sq ft, with the exception of the Bli-Nix which was applied at 2.0 gal/1000 sq ft. Spray schedule treatments were first applied on 5 May, before brown patch was observed, with remaining applications made thereafter according to the schedules indicated in the tables (final application on 12 Aug). Brown patch assessments were based on percent plot affected and ratings of verdure loss within patches (verdure is plant vigor measured by percent green foliage within diseased patches). The level of infestation by Poa annua was visually estimated on 1 May, when color differences between the two grass species and the presence of P. annua seed heads facilitated discrimination. The amount of P. annua per plot averaged 28.5 percent and did not differ significantly between treatments. Data for brown patch were transformed (arcsine) and analyzed using ANOVA (alpha=0.05) and Waller-Duncan kratio t-test, (k=100). Although statistics provided are based on analysis of arcsine- transformed data, arithmetic means are presented in order to provide a better indication of the level of disease control provided by each treatment as well as the overall disease pressure in the trial. Weather was generally favorable for brown patch, and disease pressure was moderate to high from end-Jul through early-Sep. With the exception of Bli-Nix plus buffer, all treatments effectively controlled brown patch. No phytotoxicity or growth regulator effects were noted." |
