| Abstract/Contents: | "Trials were conducted at Veenker Memorial Golf Course in Ames, Iowa. Creeping bentgrass was maintained at 0.16-in. cutting height. Fungicides selected for activity against dollar spot were applied using a backpack sprayer at 30 psi and a dilution rate of 5 gal per 1000 sq ft. The experimental design was a randomized complete block with four replications. All plots measured 4 ft x 5 ft. Spray applications were initiated on 4 Jun, except for curative treatments, which were initiated on 1 Jul. These were followed by re-applications at recommended intervals until 13 Aug. Visual estimates of disease severity (% dollar spot) were made at approximately 7-day intervals starting on 23 Jun. Data were analyzed using the GLM procedure in SAS and mean separations were determined using Fisher's protected LSD at P=0.05. Disease pressure was moderate. Early in the season, there was dollar spot sporadically dispersed across the plot, seemingly worse in plots were disease was unchecked the previous year. Due to a long dry spell in July, there was very little disease by early August in any treated plot and only 3.5% disease in the unsprayed check. Most of the tested products suppressed dollar spot significantly in comparison to the unsprayed check. No phytotoxicity symptoms were observed during the trial." |
