[目的]明确10%硫氟肟醚悬浮剂对茶树茶毛虫的防治效果及使用剂量。[方法]采用田间茎叶喷雾法检测防治效果,以邓肯氏新复极差法检验差异显著性。[结果]10%硫氟肟醚悬浮剂45~135 g a.i./hm2剂量处理茶树茶毛虫,药后15 d防治效果达72.94%~93.26%,比对照药剂10%氯氰菊酯乳油防效好。[结论]10%硫氟肟醚悬浮剂以90~135 g a.i./hm2(制剂用量900~1350 g/hm2)剂量处理能有效控制茶毛虫的危害,可以在生产上推广应用。
[Objective] The research aimed to clarify the control effect and dosage of 10% thiooxime ether suspension on tea tea caterpillar. [Method] The control effect of spraying stems and leaves in field was tested, and the difference significance was tested by Duncan ’s new repolarization method. [Result] The control effects of 10% thiooxime ether SC from 45 ~ 135 g a.i./hm2 on tea tree caterpillars reached 72.94% ~ 93.26% on the 15th day after treatment, which was better than that of the control 10% cypermethrin EC. [Conclusion] The treatment of 10% thiooxetine SC with 90 ~ 135 g a.i./hm2 (dosage of 900 ~ 1350 g / hm2) could effectively control the damage of tea caterpillars and could be widely applied in production.
