Abstract/Contents:"Studies were conducted at the University of Florida, West Florida Research and Education Center near Jay, FL during 2001 and 2002 to evaluate flazasulfuron for control of both annual and perennial weed species in bermudagrass. At 4 wk after treatment (WAT), flazasulfuron (0.022 lb a.i./A) controlled southern crabgrass [Digitaria ciliaris (Retz.) Koel.] equal to MSMA (85 to 90%). By 14 WAT the rate needed to maintain 85% control increased to 0.0032 lb/A. Flazasulfuron applied three times at 0.70 lb/A, with treatments spaced 3 wk apart, provided better torpedograss (Panicum repens L.) control (80%) than a single treatment at the same rate (60%) when evaluated 8 wk after initial treatment (WAIT). Torpedograss control with the sequential program was comparable to that observed with the standard quinclorac 21 WAIT. Bahiagrass (Paspalum notatum Fluegge) control was less than 50% with a single application of flazasulfuron. A single application was also in effective for control of Virginia buttonweed (Diodia virginiana L.). However, two sequential applications improved Virginia buttonweed control to 70% while three application provided 90% control 11 WAIT. Flazasulfuron provided more consistent control of purple nutsedge (Cyperus rotundus L.) and cocks-comb kyllinga (Kyllinga squamulata Thonn. ex Vahl) when applied twice compared with a single treatment. The sequential treatment controlled these species similar to the standard halosulfuron. Flazasulfuron was also effective for removing ryegrass overseeding and provided 90% control 3 WAT"
