| Abstract/Contents: | "The introduction of herbicide resistant turfgrass warrants information regarding selective postemergence control of common turfgrass species. Field experiments were conducted in New Jersey, Indiana, Virginia and Maryland in 2004 to evaluate the response of Kentucky bluegrass to postemergence herbicides. Herbicides tested included glyphosate, glufosinate, fluaziflop, clethodim, sethoxydim, foramsulfuron, trifloxysulfuron, and rimsulfuron. Initial applications were made in late July or early August with repeated applications after one month. Single applications of glyphosate and glufosinate at 1.5 and 1 lb ai/A, respectively, provided 100% control two to four weeks after initial treatments. Forumsulfuron, trifloxysulfuron and rimsulfuron applied at 0.03 lb ai/A generally required two applications to provide complete bluegrass control. Single applications of fluaziflop at 0.38 lb ai/A provided minimal bluegrass reductions but repeated applications gave 65 to 100% control after 8 weeks. Single applications of clethodim and sethoxydim at 0.25 and 0.47 ai/A, respectively, had inconsistent results over the four locations but repeated applications gave 60 to 100% bluegrass control after 8 weeks. Results suggest glyphosate and glufosinate effectively control Kentucky bluegrass with single applications while other postemergence herbicides have variable control and may require repeated applications. |
