| Abstract/Contents: | "Field studies were conducted in the summer of 2006 and 2007 to evaluate the response of tall fescue 'Avenger', and perennial ryegrass Gator 3 to bispyribac-sodium herbicide. Annual bluegrass control was also evaluated. In 2007, fine fescue Ambassodor was also included. Sequential applications of bispyribac-sodium were applied at rates ranging from 37 g ai/ha to 296 g/ha at approximately a three week interval. Experiments were initia ted on May 30 and May 31 in 2006 and 2007, respectively. All treatments were applied using a single nozzle CO2 pressured sprayer calibrated to deliver a total of 375 L/ha. Nozzles used were 9504E and CO2 regulators were set for 220 kPa. Experimental design was a randomized complete block with four replications. Turfgrass chlorosis was ra ted on a percent scale where 0 equaled no chlorosis and 100 equaled complete desiccation. Annual bluegrass (Poa annua) cover was evaluated prior to herbicide application a nd 10 weeks after initial treatment (WAIT). In 2006, bispyribac-sodium caused some chlorosis to tall fescue and perennial ryegrass; however injury did not exceed 20%. The highest levels of chlorosis were observed 10 days following t he sequential applicat ion of bispyribac-sodium at 222 and 296 g/ha. All bispyribac-sodium treatment s provide substantial control of annual bluegrass but rates exceeding 74 g/ha were requi red to obtain nearly complete control, especially in perennial ryegrass. In 2007, tall fescue and perennial ryegrass injury did not exceed 5% at any evaluation time. Fine fescue was not injured by bispyribac-sodium. By 6 WAIT, annual bluegrass control was only 24, 65, and 78% in tall fescue when bispyribac-sodium was applied at 74, 148, and 222 g/ha, respectively. However, 296 g/ha provided nearly complete control. Control levels in perennial ryegrass tended to be greater but rates above 74 g/ha were required to achieve 80% or greater control." |
