摘要
采用浸叶法测定了鱼藤酮与印楝素混配后对防治小菜蛾3龄幼虫的增效作用及最佳配比。结果表明:当鱼藤酮:印楝素位于7.52∶2.16和7.20∶3.60之间时,混配药剂表现出增效作用;当2种药剂混配比为7.52∶2.16时,增效作用最强,共毒系数最高为164。
This test measured the synergism of rotenone and azadirachtin against PluteUa xyllostella L with immerse leafs method, and confirmed the best ratio. The results showed that the mixture of rotenone and azadirachtin had synergic action, the CTC was the highest to 164with the ratio of 7.52 ： 2.16.
