摘要
为进一步了解印楝素对贵州茶区茶树主要害虫的田间防治效果以及其对天敌、茶树植株的影响,以0.3%印楝素乳油和30%印楝油为供试药剂进行了田间试验。结果表明：这两种药剂在大田中单独施用后防治茶小绿叶蝉较为理想,最高防效可达91.82%~94.87%,同时速效性好,持效期长,可维持在14 d以上,且对茶树生长安全、对天敌亦无影响,推荐施用剂量分别为90和30 m L/667m2。
Using azadirachtin 0.3% EC and 30% neem oil as test fungicides, field experiment was conducted to evaluate the control efficiency of Azadirachtin to tea green leafhopper in Guizhou. The results showed that azadirachtin 0.3% EC and 30% neem oil could effectively control the tea green leafhopper with quickly toxicity and long active duratation（more than 14 days）, the control efficiency reached 91.82%-94.87%. The tea plant and the natural enemies were unaffected. Azadirachtin 0.3% EC and 30% neem oil could be recommended for the tea green leafhopper control, and the recommended dose is 1 350 m L/hm2 and 450 m L/hm2, respectively.
