摘　　要：[目的]明确43%联苯肼酯悬浮剂对苹果红蜘蛛的防治效果,为农药登记及示范推广提供科学依据。[方法]2014、2015年以当地常用药剂15%哒螨灵乳油为对照药剂,在苹果树上进行该药剂防治苹果红蜘蛛的田间药效试验。[结果]43%联苯肼酯悬浮剂除最低剂量(有效成分160 mg/L)药后1、5、10 d的防效低于对照药剂外,其高剂量(有效成分240 mg/L)和中剂量(有效成分200 mg/L)药后各天的防效均显著高于或相当于对照药剂。[结论]43%联苯肼酯悬浮剂对苹果红蜘蛛有良好的速效性,持效期可达10 d以上,且对苹果蚜虫有一定的兼治作用,对作物安全。[Aims] The paper aims to assess the control efficacy of bifenazate 43% SC on European red mite and to provide a scientific basis for pesticide registration and demonstration promotion. [Methods] The control efficacy of bifenazate 43% SC on European red mite was tested by using pyridaben 15% EC as the control in 2014 and 2015. [Results] The results showed that compared with control reagents, the efficacy of bifenazate 43% SC at the dosage of 160 mg/L after 1, 5, and 10 d was significantly lower, while the other two dosages at 200 and 240 mg/L were significantly higher or equivalent to the control reagents. [Conclusions] The study showed that the bifenazate 43% SC has quick availability and persistence after 10 d. In addition, it also has control efficacy against apple aphid to a certain extent, and is safe to apple growth and environment at the tested dosage.
