摘要:

为筛选适用于防治梨园二斑叶螨的药剂,开展田间药效试验。结果表明:药后3 d,各药剂处理的防治效果为63.93%~74.59%,药后7 d防治效果为71.55%~83.04%,药后14 d防治效果为75.97%~86.80%,前期整体防治效果不高,后期防治效果有所上升。其中,20%丁氟螨酯悬浮剂+43%联苯肼酯悬浮剂处理14 d后的防治效果最高,可达86.80%,其次是43%联苯肼酯悬浮剂和22%阿维菌素·螺螨酯悬浮剂,14 d后的防治效果分别为85.84%和83.05%。以上3种农药可以在当地梨树上推广应用,不推荐施用20%丁氟螨酯单剂。

Abstract:

In order to screen the agents suitable for the control of Tetranych urticae Koch in pear orchards, field efficacy tests were carried out. The results showed that the control efficacy of each agent was 63.93%-74.59% on 3 days after treatment, 71.55%-83.04% on 7 days after treatment, and 75.97%-86.80% on 14 days after treatment. Among them, the control efficacy of 20% cyflumetofen suspension+ 43%bifenazat suspension was the highest after 14 days, reaching 86.80%, followed by 43% bifenazide suspension and 22% avermectin-spirofenolate suspension, with 85.84% and 83.05% after 14 days, respectively. The above three pesticides can be popularized and applied on local pear trees, and a single dose of 20% butafenoxoxil is not recommended.
