| Abstract/Contents: | "Fungicides were evaluated on an established stand of a 'Cato' plus 'Crenshaw' blend of creeping bentgrass on a sand-based putting green at the Rocky Ford Turf Research Center, Manhattan KS. The turf was mowed to a height of 0.156-in. and irrigated daily for 15 min. The area was fertilized biweekly with 0.25 lb nitrogen (N)/1,000 ft2 during Mar through Jun and 0.16 lb N/1,000 ft2 during Jul through Nov. Fungicide applications were made at variable intervals beginning 24 May using a CO2-powered boom sprayer equipped with two XR Tee Jet 8004VS nozzles at 30 psi in water equivalent to 2.0 gal/1,000 ft2. Plots were 4 ft x 5 ft and arranged in a randomized complete block design with four replications. Plots were assessed periodically by visually estimating the percentage of each plot affected by dollar spot infection centers. Dollar spot was present on several rating dates and did not exceed 10% severity in the untreated controls during the course of the experiment. All fungicides reduced dollar spot symptoms to < 2.5% severity and most treatments reduced disease compared to the untreated control. There were no significant differences among treatments. Phytotoxicity, evident as slight thinning and suboptimal color, was observed in the Concert treatments on 3 rating dates, typical of repeated applications of demethylation inhibitor fungicides in turfgrass. Concert contains the DMI fungicide propiconazole. No phytotoxic effects were observed in Reserve treatments, which contain the DMI fungicide triticonazole." |
