| 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 1.5 lb N/1000 sq ft as urea on 26 Oct 06, 1.5 lb N/1000 sq ft as urea on 8 Nov 06, and with 1.0 lb N/1000 sq ft as urea on 28 Jun 07. 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. The treatments were first applied on 24 Apr, a few days after dollar spot was observed, with remaining applications made thereafter according to the spray interval indicated in the tables (final application on 31 Jul). The Trinity product arrived late and was first applied on 22 May, when the dollar spot epidemic was under way. Visual counting of dollar spot infection centers was performed weekly. 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% and did not differ significantly between treatments. Data for dollar spot were transformed (log10) and analyzed using ANOVA (α=0.05) and Waller-Duncan k-ratio t-test, (k=100). Although statistics provided are based on analysis of log10 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 moderately favorable for dollar spot activity during the test period, and disease pressure was moderate throughout the test. Most treatments provided acceptable control of dollar spot for most of the duration of the test, with the exception of the Disarm and the SoilGard 12G treatments. The Trinity treatments were not started until 22 May; there was a steady decline in dollar spot after that time until the end of the trial for those treatments. No phytotoxicity or growth regulator effects were noted." |
