摘要
[目的]通过田间药效试验，筛选出一批高效低毒、选择性较强的新药剂在茶园推广应用。[方法]设置8个药剂处理和1个空白对照处理，开展防治茶尺蠖的田间药效试验。[结果]25 g／L溴氰菊酯乳油、100 g／L联苯菊酯乳油、25 g／L高效氯氟氰菊酯乳油的防治效果较好。生物农药中0．4％蛇床子素乳油的防效最好。[结论]25 g／L溴氰菊酯乳油、100 g／L联苯菊酯乳油、25 g／L高效氯氟氰菊酯乳油在茶尺蠖大发生时，可以有效控制其危害。生物农药中0．4％蛇床子素乳油是防治茶尺蠖的首选药剂。
Abstract
Objective] To screen a batch of new agents with high efficiency, low toxicity and strong selectivity for tea garden by using field drug efficacy test.[Method] A total of 8 pharmaceutical treatments and 1 blank control treatment were designed.Field efficacy experiment on the control of Ectropis obliqua hypulina Wehrli was carried out.[ Result] 25 g/L Deltamethrin EC, 100 g/L bifenthrin EC and 25 g/L lambda-cyhalothrin EC had relatively good control efficiency.And in biopesticide, 0.4% osthole EC had the best control efficiency.[ Conclusion] 25 g/L Deltamethrin EC, 100 g/L bifenthrin EC and 25 g/L lambda-cyhalothrin EC can effectively control the damage of E.obliqua outbreak. In biopesticide, 0.4% osthole EC is the first choice for E.obliqua control.
