Abstract/Contents: | "The experiment was conducted on tall fescue at the Sandhills Research Station in Jackson Springs, NC. The tall fescue plots were planted the previous fall and received standard management. Each treatment was applied on a 14, 21, or 28-day interval. All treatments were applied on 10 Jun and repeated at the appropriate interval. Treatments were applied with a pressurized CO2 backpack sprayer in 2.5 gal water/1000 ft2. Treatments were arranged in a randomized complete block design with four replications; plots were 5 ft wide by 10 ft long. Air temperature at the time of applications averaged 88 F and soil temperature averaged 84 F. The test period was very hot and dry. Disease severity was rated every 2 wk and turf quality was evaluated at the end of the test. White patch was also present in the test plots. Disease pressure was moderate due to lack of rain. The most effective treatments were Lynx 25DF at 0.5 oz, with and without surfactant, ASC66825 50WP at 2.5 oz, SAN832F 50WP at 4.0 oz, RH-0611 NA at 6.0 oz, and Sentinel 40WG at 0.63 oz. The biocontrol used, a binucleate Rhizoctonia sp., had no effect on the brown patch. The other non-fungicidal treatments also were not effective." |
