| Abstract/Contents: | "Fungicide treatments were evaluated on an experimental bentgrass green at the Turf Field Center, NCSU, Raleigh, NC. The bentgrass was seeded in the Fall and maintained at a 0.25 in height. The soil was a "sand-amended" Cecil clay loam (ph ~ 6.5). The area was managed as recommended for a bentgrass golf green. A 16-4-8 fertilizer was applied twice during the Fall and once in the Spring at a rated of 1lb of N/1000 ftâ‚‚). The turf was treated with a half-rate(1.3 lb/1000 ftâ‚‚) of Scotts Goosegrass/Crabgrass control 6.46G herbicide in the Spring. Treatments were arranged in a randomized complete block design with four replications of plots 5 ft by 5 ft. 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/1000 ftâ‚‚. Air temperature on days of applications averaged 85 F and soil temperature averaged 82 F. Treatments were initiated on 27 Jul and repeated on a 14 day interval. Turf quality, turf color, and % brown patch were visually rated on 16 Aug. Conditions for disease development were moderate during the test period. Sentinel 40WG at 0.25 oz, EXP80318 1 FL at 1 fl oz, and ICI5504 50WG at 0.4 oz provided the most effective control of brown patch. Plots treated with ICI5504 50WG at 0.4 oz had the highest overall turf quality. The new bentgrass cultivar, `Crenshaw', did not show any phytotoxic effects from the fungicides and recovered quickly from brown patch when treated with effective fungicides." |
