对９种除草剂和７个复方进行了系统的筛选测定．结果显示，嗪草酮、阿特拉津、草坪２号、草坪３号和草甘膦对铜锤草具有高效，药后 ２０ ｄ防效为 ８８．６６％－９９．１０％；药后 ７ ｄ，草坪 １号对铜锤草致死中浓度 ＬＣ_(５０)为 １０６．６７ ｍｇ／Ｌ，表现出很高的杀草活性，且对草坪草的生长没有任何影响，草甘膦虽然对铜锤草具有高效，但在本试验浓度范围内，对草坪草的生长有不同程度的抑制作用 Nine herbicides and seven compounds were systematically screened. The results showed that metribuzin, atrazine, lawn 2, lawn 3 and glyphosate were effective on the copper hammer grass, and the control effect was 88.66% -99.10% on the 20th day after drug treatment. After 7 d. The LC_ (50) of turfgrass No. 1 to the lethal concentration of M. pumila was 106.67 mg / L, which showed high herbicidal activity and had no effect on the growth of turf grass. Grass is highly efficient, but inhibits the growth of turf grass to varying degrees within the concentrations tested in this study
