| 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 three times per week at a height of 0.50-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 at 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 × 5 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 15 May and ended 17 Jul. 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. Applications were made at 21-day intervals. Data was transformed by arcsine square root (y) and analyzed using analysis of variance followed by Tukey's HSD (Honestly Significant Difference) for means separation (Α=0.05). Visual 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 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. Dollar spot was moderate at the beginning of the study, became severe by 6 Jun, declined due to unfavorable environmental conditions until 28 Jun and then remained severe until the end of the study. The Tartan treatments (1.5 and 2.0 fl oz) performed well and reduced the disease to acceptable levels with a single application. After the second application all treatments provided acceptable control and maintained control throughout the study. No phytotoxicity or growth regulation effects were noted." |
