摘要
采用盆栽和室内试验,测定了几种新药剂对茶叶瘿螨的防效。结果表明,99%矿物油乳油100~200倍和0.6%苦参碱水剂1000~2000倍、0.3%印楝素可溶液剂500倍和1.5%除虫菊素水乳剂500倍,药后7 d的防效均在90%以上。矿物油和3种植物源农药对茶叶瘿螨有良好的防治效果。
The control effects of several new pesticides on Calacarus carinatus were determined by the pot and labo-ratory experiments.The results show that the control efficacies of 99%mineral oil emulsion(100~200 times)and 0.6%matrine aqueous solution(1000~2000 times)and 0.3%azadirachtin aqueous solution(500 times)and 1.5%pyrethrin aqueous emulsion(500 times)were all above 90%on the 7th day after spray.The mineral oil and the three plant pesticides tested had good control effects on Calacarus carinatus.
