| Abstract/Contents: | "The test was conducted at The Ohio State University Turfgrass Research Center, Columbus, OH on a stand of creeping bentgrass established in 1983. Turf was mowed at 0.50-in. three times per week 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 at 0.5 lb nitrogen/1,000 sq ft was made 4 Apr. The soil was Crosby B silt loam, pH 7.3. Treatment plots measured 6 ft x 10 ft with 1-ft alleys between plots, and 2 ft between blocks, and were arranged in a randomized complete block design, with four replications. All treatments were initiated on 23 Apr and reapplied on 2 Jun. 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 gal water/1,000 sq ft) for all treatments. Data was transformed by arcsine square root (y) and analyzed using analysis of variance followed by means comparisons using Tukey's HSD (Honestly Significant Difference) with α=0.05. Counting of dollar spot infection centers were taken weekly. The average maximum and minimum air temperatures (°F) and total precipitation (in.) for each month respectively were: May 70.5, 48.2, and 2.78; Jun 82.8, 61.3 and 8.70; Jul 84.5, 62.7 and 1.28. Dollar spot was not active at the beginning of the study. The disease became active in early May with the development of symptoms and continued to increase in severity throughout the study. All treatments gave satisfactory disease control for 9 weeks and Tourney + Daconil and Emerald gave exceptional disease suppression for 11 weeks. No phytotoxicity or growth regulation effects were noted." |
