| Abstract/Contents: | "This report discusses several preemergence and postemergence herbicides that have been registered for use on warm-season turfgrasses in the United States within the last four years. Prodiamine applied as preemergence at 0.84 kg ha-1 effectively controlled crabgrass (Digitaria spp) and goosegrass [Eleusine indica (L.) Gaertn.]. Dithiopyr at less than or equal to 0.56 kg ha-1 has preemergence and early postemergence activity on crabgrass, but requires a rate > 0.56 kg ha-1 for consistent goosegrass control (greater than or equal to 80%). Isoxaben applied preemergence controls numerous species of annual broadleaf weeds. Early postemergence application of diclofop controls goosegrass and fenoxaprop cotnrols crabgrass. Rates of either herbicide must be increased to control grass weeds in the tiller grwoth stage, compared with early leaf growth stage. Fenoxaprop use on warm-season turfgrasses is limited to zoysiagrass. Quinclorac effectively controls crabgrass when applied as early postemergence, but not when applied as preemergence. Other recent registrations on warm-season turfgrasses are metolachlor, metsulfuron, sulfometuron, and chlorsulfuron. Metolachlor applied as preemergence has exhibited activity on yellow nutsedge (Cyperus esculentus L.) and crabgrass species. Metsulfuron applied as postemergence controls a large number of annual and perennial dicot weeds. Sulfometuron is applied mainly as postemergence for control of annual and perennial grass and broadleaf weeds. Chlorsulfuron can be used for selective spot tall fescue (Festuca arundinacea Schreb.) control." |
