本文研究了2.1%氯·阿乳油对菜粉蝶的室内毒力和田间防效。结果表明,2.1%氯·阿乳油在室内对莱粉蝶的共毒系数为204.3;田间使用1000~2000倍液,药后1~3d对菜粉蝶的防效为86.8%~100%,药后7d达97.8%~100%。
In this paper, 2.1% chlorine · Emulsion on cabbage butterfly indoor toxicity and field control. The results showed that the co-toxicity coefficient of 2.1% chloro-EC was up to 204.3 indoors, and 1000 to 2000 times in the field. The control effect on cabbage butterfly from 1 to 3d after treatment was 86.8% 100%, 7d after drug reached 97.8% ~ 100%.
