Abstract/Contents: | "The experiment was conducted on 4-yr old `Pennlinks' creeping bentgrass maintained as an experimental putting green at the Pee Dee Research and Education Center near Florence, SC. The soil was a Norfolk sandy loam, pH 5.8. THe turfgrass was mowed every other day, at 0.1875-inch cutting heights, using a commercial reel mower. Throughout the trial, plots were fertilized weekly with 21-3-21 greens grade fertlilizer at 0.25 lb N/1000 sq ft. The entire area was treated once with Orthene Turf, Tree and Ornamental WSP at 2.4 oz/1000 sq ft. for suppression of cutworms. The site was naturally infested with Rhizoctonia solani. All treatments were first applied on 7 Jun 96 and continued on a 14-day schedule. Sprays were applied with a 2 nozzle shielded boom sprayer, with Teejet 8002ER tips, and 30 psi spray pressure at the boom. Diluent rate was 2.04 gal/1000 sq ft. Treatments were arranged in a randomized complete block design, with 4 replications. All plots measured 3 ft x 5 ft. Disease severity and a percent of the plot area with brown patch symptoms, and turf quality were rated weekly, with the first rating on 21 Jun. Data presented represent percent disease and turf quality at the end of a spray interval. Disease severity was moderate throughout the test period, reaching a high in check plots of only 31%. Temperatures were moderate throughout the summer, rarely exceeding 90⁰ F, with average irrigation or rainfall to the plots of at least 1 inch per week. Daconil formulations performed similarly throughout the trial, giving good disease control of brown patch. Addition of Banner generally improved control of brown patch. The addition of Aliette Signature with Daconil Ultrex compared to Aliette 80WDG with Daconil Ultrex improved brown patch control and turfgrass quality at several rating dates." |
