| Abstract/Contents: | "Fungicide treatments were evaluated on an experimental bentgrass green at the Turf Field Center, NCSU, Raleigh, NC. The plots received conventional golf course management and were maintained at a 0.25 in height. The soil was a "sand-amended" Cecil clay loam (ph~6.5). The turf was treated with a half-rate (1.3 lb/1000 ftâ‚‚) of Scotts Goosegrass/Crabgrass control 6.46G herbicide in the Spring. A 16-4-8 fertilizer was applied twice during the Fall and once in the Spring at a rate of 1 lb of N/1000 ftâ‚‚. Treatments were arranged in a randomized complete block design with four replications of plots 5ft by 5ft. All treatments were applied with a 12 volt diaphragm pump sprayer at 40 psi using 8004 VP flat-fan Teejet nozzles at a rate of 2.5 gal water 1000ftâ‚‚. Air temperature on days of application averaged 84 F and soil temperature averaged 80 F. Treatments were initiated on 10 Jun and repeated on corresponding 14 or 28 day intervals. Turf color, overall turf quality, and % brown patch were rated periodically. Conditions for disease development were moderate during the test period. Most treatments provided excellent control of brown patch. Plots treated with ICI5504 50WG at 0.4 oz on a 14-day schedule had the highest overall turf quality. Growth regulating effects (dark green color and coarse texture) were observed in plots treated with Sentinel 40WG, Banner 1.1EC, and EXP10452 50 WG. Severe dollar spot developed in plots treated with ICI5504 WG50 at 0.4 oz." |
