Kikuyugrass (Pennisetum clandestinum Hochst.) an aggressive weed of cool season turfgrass in coastal California, Spreads rapidly by growth of robust stolons and seedlings. Kikuyugrass competition was studied by placing plugs of six turfgrasses in a kikuyugrass sward. Plug diameters increased when triclopyr (.56kg ai/ha) or quinclorac (.74kg ai/hg) were repeatedly applied (4 times) in combination with MSMA (2.2kg ai/ha). These herbicide combinations also eradicated kikuyugrass in lawns of cool season turfgrass. Kikuyugrass density was reduced from 75% of the turfgrass sward to 0%. Resurgence of kikuyugrass has not exceeded 5% 4 months posttreatment.
