Control:
Chemical: "Probably susceptible to: 1) many residual herbicides at standard rates; 2) translocated herbicides including glyphosate and 2,4-D before flowering; 3) contact herbicides, including paraquat, while seedlings; however, established plants will probably recover from the base" (Swarbrick, 1997).
Biological: Liothrips mikaniae was introduced into Solomon Islands in 1988, but failed to establish (Swarbrick, 1997). "A number of very promising, and probably specific, natural enemies are known in Central and South America… Of these a thrips Liothrips mikaniae appears to be specific and to have considerable potential as a biological control organism. A bug Teleonemia sp., several beetles and an eriophyid mite Acalitus sp. also warrant serious consideration. A number of other natural enemies of little known specificity also attack M. micrantha." (Waterhouse and Norris, 1987)
