| Abstract/Contents: | "The test was conducted on a Maury silt loam located at the University of Kentucky Turf Research Center near Lexington. The turf was maintained at 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 14 Oct 07. Plots measured 4 ft x 4 ft with 2-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. Most treatments were first applied on 7 May, after dollar spot was first detected, with the remaining treatments applied according to the spray intervals indicated in the table (final application on 14 Aug). Banner MAXX/ Daconil Ultrex treatments were applied only once each to see if they could delay the onset of dollar spot. Bli-Nix with Buffer was first applied 18 April. Where tank-mixes were alternated, sprays were applied every two weeks, with each tank-mix being applied once every four weeks. Visual counting of dollar spot infection centers was performed weekly. Selected, representative data are provided due to space constraints. 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 51.5% and did not differ significantly between treatments. Transformed data (log10) were analyzed using ANOVA (alpha=0.05) and Waller-Duncan k-ratio t-test, (k=100). Although statistics provided are based on analysis of 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. This reporting approach may lead to discrepancies between the rankings of treatments based on the arithmetic means and those based on the statistics provided in the table. Disease pressure was low to moderate in this test. Most treatments provided acceptable control of dollar spot for most of the duration of the test, with the exception of Bli-Nix with Buffer, Cleary's 26/36 and Trinity 208SC. Thiophanate methyl-resistant strains of S. homoeocarpa are known to inhabit the site of the test. Banner MAXX/ Daconil Ultrex treatment applied on 29 Apr may have delayed the epidemic of dollar spot better than the treatments in late March or early June, but the effect was modest." |
