Herbicide program can control kikuyugrass in cool-season turf

Abstract

Kikuyu grass is an invasive perennial weed of turf grass in California. Currently, complete renovation of infested turf is the most practical means of control, but this process can cost more than $1,500 per acre and it removes the sward from use for up to 3 months. A less disruptive method uses multiple selective herbicide treatments with MSMA, triclopyr or a combination of MSMA plus triclopyr. This method inhibits the competitive ability of kikuyugrass while allowing the growth of desirable cool-season turf species.
