摘要
介绍了乙草胺和莎多福不同配比混用室内毒力测定及大田药效试验。结果表明乙草胺∶莎多福按 3.3～ 7.5∶1的比例混配 ,对稗草的防效达 95%以上 ,四叶萍的防效达 90 %以上 ,莎草防效达 1 0 0 %。水稻增产幅度大于 1 0 % ,对大苗移栽水稻安全。
The indoor toxicity evaluation and field tests of mixtures Acetochlor and Cinosulfuron at different proportion were indroduced. The results showed that the optimum proportion was acetochlor/Cinosulfuron 3.3～7.5∶1.
