| Abstract/Contents: | "The test was conducted at The Ohio State University Turfgrass Research Center, Columbus, OH on a stand of creeping bentgrass established in 2004. Mowing height was 0.17-in. with clippings removed and the area was irrigated as needed. The condition of the sward was good with fair color, minimal thatch and good density. A single fertilizer application of 18-5-11 (0.125 lb nitrogen/1,000 sq ft) was made 4 Apr. The soil was Crosby B silt loam, pH 7.3. Treatment plots measured 3 ft x 5 ft with 1-ft alleys between plots, and 3 ft between blocks, and were arranged in a randomized complete block design, with four replications. Applications were made at 7-, 14-, or 21-day intervals. All treatments were initiated on 15 May and last application 7 Aug. Applications were made with a hand-held, CO2-powered boom sprayer using 6503 TeeJet nozzles at a pressure of 40 psi (water equivalent to 2.0 gal water/1,000 sq ft) for all treatments. Counting of dollar spot infection centers in plots were done weekly. Data was sujected analyzed using analysis of variance followed by means comparisons using Tukey's HSD (Honestly Significant Difference) with α=0.05. The average maximum and minimum air temperatures (°F) and total precipitation (in.) for each month respectively were: May 80.7, 49.1, and 0.30; Jun 83.5, 57.8 and 3.48; Jul 84.2, 58.7 and 3.81; and Aug 89.7, 64.1 and 2.67, respectively. No disease was present at the initiation of the study. Dollar spot developed slowly in Jul and increased to a moderate level in early Aug. Most treatments provided excellent preventative control of dollar spot. Insignia treatments provided considerable suppression of disease compared to the untreated control. No phytotoxicity effects were noted." |
