| Abstract/Contents: | "Centipedegrass is a warm season, perennial grass that is often used in the southeastern United States for limited wear areas such as lawns, industrial sites and along roadsides. Due to its slow, stoloniferous growth habit and poor tolerance to postemergence herbicides, grass weeds often invade centipedegrass areas. Research was conducted at Clemson, South Carolina with the objective to determine the phytotoxicity of single and sequential applications of six postemergence herbicides on centipedegrass. Sethoxydim and fluazifop were applied at 0.10, 0.20, and 0.30 kg/ha and haloxyfop, xylafop, fenoxaprop, and SC-1084 at 0.07, 0.15, and 0.30 kg/ha. Each treatment has crop oil concentrate added at 2.4 1/ha. Sequential treatments at the same initial rate were applied to the same plots 28 days after the first application. Treatments were arranged in a randomized complete block design with three replications and applied with a CO2-pressurized backpack sprayer. Tests were repeated. Turf color was visually estimated using a 1 to 9 scale, with 1 as bare ground, 6.5 as acceptable and 9 as best. Stand density was visually estimated using a 0 to 100 scale, with 0 as bare ground and 100 as total turf vegetative coverage. Turf color and density were unaffected by single or repeat applications of sethoxydim through 70 days after treatment. Single applications of fenoxaprop and SC-1084 at 0.07 kg/ha provided acceptable turf color and density 40 days after treatment. Unacceptable turf color and density was observed with single and sequential application of fluazifop, haloxyfop, xylafop, and with sequential application of SC-1084 and fenoxaprop." |
