| Abstract/Contents: | "Studies were conducted at the University of Florida, West Florida Research and Education Center, Jay, FL to evaluate CGA 362622 for control of both annual and perennial weed species in bermudagrass and turfgrass tolerance in bermudagrass and St. Augustinegrass. At 2 wk after treatment (WAT), CGA 362622 (30 g a.i./ha) controlled southern crabgrass [Digitaria ciliaris (Retz.) Koel.] equal to MSMA (95%) but was less effective than MSMA 5 WAT (60 vs. 95%). CGA 362622 applied twice at 50 g/ha, with treatments spaced 6 wk apart, provided better torpedograss (Panicum repens L.) control (95%) than a single treatment at 75 g/ha (65%) when evaluated 12 WAT. Torpedograss control with the sequential program was comparable to that observed with the standard quinclorac + diclofop. Bahiagrass (Paspalum notatum Fluegge) control was similar for both CGA 362622 (30 g/ha) and MSMA (85% 2 WAT, 65% 15 WAT). Control was improved to 95% 15 WAT when CGA 362622 (20 g/ha) was mixed with MSMA. CGA 362622 (25 g/ha applied twice) provided 90% Virginia buttonweed (Diodia virginiana L.) control 9 WAT but control declined to 70% 15 WAT. Single applications of CGA 362622 (50 g/ha) controlled purple nutsedge (Cyperus rotundus L.) (90%) nearly as well as sequential treatments (95%) and better than halosulfuron or MSMA alone. A sequential treatment of CGA 362622 (25 g/ha) provided 95% control of cocks-comb kyllinga (Kyllinga squamulata Thonn. es Vahl) 17 WAT, better than halosulfuron (80%). Bitterblue, Delmar, Floratam, Palmetto, and Raleigh cultivars of St. Augustinegrass tolerated single application of CGA 362622 up to 50 g/ha. Bitterblue, Floratam and Raleigh tolerated one application at 75 g/ha. None of the cultivars tolerated multiple application of CGA 362622. The dwarf bermudagrass cultivars TifEagle, Floradwarf and Tifdwarf tolerated CGA 362622 at rates up to 75 g/ha." |
