摘 要：
采用田间试验方法,研究了克草胺乳油防除稻田杂草药效试验。结果表明在水稻移栽5～7d,水稻缓苗后施用质量分数为47%克草胺乳油,有效剂量为352 5～1057 5g hm2,对稗草的防效为95 7%～100%,对各种阔叶杂草的防效为87 4%～99 7%,对杂草鲜重的抑制效果为84 3%～95 0%,杀草谱广,防效持久,水稻增产64 4%。

摘 要：
By filed trials, control effect of 47% Kecaoan emulsfiable concentrate against rice field weeds was studied. The results showed that excellent weed control performance was achieved when 47% Kecaoan emulsfiable concentrate was applied at 5～7 days of post-transplanting and within the application dosage of 352.5～1 057.5 g/hm~2. The average control effect against barnyardgrass reached 95.7%～100%, and 87.4%～99.8% against all kinds of broadleaf weeds. The inhibition effect to weed fresh weight reached 84.3%～95.0%. 47% Kecaoan EC is a herbicide of a wide spectrum and a persistent control effect. Rice yield increased by 64.4%.
