| 摘 要： | 通过温室盆栽试验，研究茎叶喷施硝磺草酮对反枝苋、稗草和千金子的活性及对玉米的安全性。结果表明硝磺草酮对玉米和反枝苋、千金子、稗草的选择性指数分别为6．73、5．95、5．34。说明硝磺草酮对玉米和杂草的选择性很强，可安全地使用茎叶处理法防除玉米田杂草。

| Abstract: | Pot experiments were conducted in greenhouse to investigate the bioactivity of mesotrione to Amaranthus retroflexus,Leptochloa chinensis and Echinochloa crusgalli and its selectivity to corn. The selective index of mesotrione between corn and A. retroflexus, L. chinensis and E. crusgalli were 6.7,6. 0, and 5.3 respectively, showing that the selectivity of mesotrione to corn and weeds was very strong,and that weeds in corn fields could be safely controlled by postemergence application of mesotrione. |
