| Abstract/Contents: | "Fungicides were evaluated on an established stand of 'Penncross' 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, irrigated daily for 15 min, and fertilized with 5.52 lb/1,000 ft2 total N during the season. Applications were made at 2, 3, or 4-wk intervals beginning 31 May with the final application on 20 Sep. Fungicides were applied with a CO2-powered boom sprayer with XR Tee Jet 8003VS nozzles at 30 psi in water equivalent to 2.0 gal/1000 ft2. Plots were 5 ft X 7 ft and arranged in a randomized complete block design with four replications. Plots were rated every 1 to 3 wk from 19 July through 21 September by counting the number of dollar spot infection centers per plot. Dollar spot developed at low levels in late Jul and increased through Aug and Sep. All materials provided significant disease reductions compared to the unsprayed control. Chipco 26GT, Emerald, Headway, and Spectro 90 WDG provided excellent control (less than 2 infection centers per plot) on all rating dates. Daconil Ultrex provided significant control compared to the untreated plots but the 1.8 oz rate allowed a modest amount of disease under high disease pressure late in the season. Similarly, Bayleton 50 WSP (0.5 oz on 28 d interval) provided significant control but did allow some breakthrough under high disease pressure. No phytotoxic effects were observed." |
