| Abstract/Contents: | "The test was conducted at The Ohio State University Turfgrass Research Center, Columbus, OH on a stand of creeping bentgrass greens established in 1996. Turf was mowed at a height of 0.17-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. Fertilizer applications consisted of 7-7- 7 (0.75 lb nitrogen/1,000 sq ft) applied 15 Apr and 9-9-9 (0.3 lb nitrogen/1,000 sq ft) applied 9 May. The root zone material was an USGA 85:15 mix of sand and municipal waste compost, pH 7.9. Treatment plots measured 3 ft x 6 ft with 0.5-ft alleys between plots, and 0.5 ft between blocks, and were arranged in a randomized complete block design, with four replications. All treatments were initiated on 2 Sep and ended on 30 Sep. 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: Aug 84.3, 60.8, and1.42; Sep 80.5, 57.0 and1.77. Dollar spot was not present at the beginning of the study but developed symptoms after the initiation of the applications and continued to increase in severity until late Sep. Daconil Ultrex at the 7-day interval gave a high degree of consistent disease management. Dewcure also provided very significant disease suppression in the study. No phytotoxicity or growth regulation effects were noted." |
