摘要
本文是阿高氯乳油对小菜蛾的室内毒力和增效作用进行测定评价及田间应 用的研究总结。阿高氯乳油对小菜蛾具有很高的活性。LC50为0.59mg·L ^(-1);共毒系数142.14,增效显著。室内钵栽试验5mg·L^(-1)防效85%以上,持效期10d(天)。田间试验1000~1500倍液,防效95%左右,持效期10~15d(天)。
Toxicity test and field control of Avermectin + Beta- cypermethrin against Plutella xylostella were conducted. The results i ndicated that this compound pesticide showed high level activity to P.xylostella, the LC_(50) was 0.59mg·L^(-1) and cotoxicity c oefficient was 142.14. In pot test,the control efficiency was over 85% and residual activity lasted 10 days at concentration of 5mg·L^(-1) . In the field,the control efficiency was about 95% and residual activi ty lasted 10-15 days as this pesticide was diluted to 1000 times.
