摘要
[目的]评估3种新型杀螨剂对山楂叶螨的防效。[方法]通过室内盆栽试验和田间药效试验,评价3种杀螨剂对山楂叶螨的防效。[结果]43%联苯肼酯悬浮剂和20%丁氟螨酯悬浮剂在药后3、5、7、14 d田间防治效果均高于85%,药后21 d田间螨口减退率在97%以上,表现出良好的速效性及持效性。110 g/L乙螨唑悬浮剂对害螨的速效性较差,但持效性好,药后21 d田间螨口减退率高于90%。[结论]43%联苯肼酯悬浮剂、20%丁氟螨酯悬浮剂和110 g/L乙螨唑是防治山楂叶螨有效药剂,可在大田适当轮换使用。
[Aims] The objective of this study is to evaluate the control effect with bifenazate, cyflumetofen and etoxazole against Tetranychus viennensis. [Methods] Under pot experiments and field conditions, control efficacy of the three kinds ofmiticides against T. viennensis were determined. [Results] The results showed that control efficacies were over 85% after 3, 5, 7, 14 d and the reduce rates reached over 97% which showed quick availability and persistence after 21 d by using bifenazate 43% SC and cyflumetofen 20% SC under field conditions. The reduce rates reached over 90% by using etoxazole SC at a dose of 110 g/L after 21 d, which has good quick availability and poor persistence. [Conclusions] According to the pot and field experiments, bifenazate 43% SC, cyflumetofen 20% SC and etoxazole 110 g/L SC are an effective way of controlling T. viennensis. The rotational application of the three kinds of miticides should be properly used under filed conditions.
