通过田间试验评价了48%联苯肼酯悬浮剂对苹果全爪螨、二斑叶螨、山楂叶螨3种苹果害螨的防治效果。结果表明,48%联苯肼酯悬浮剂2 000、3 000、4 000倍液对二斑叶螨的速效性较好,药后3天防效为92.51%~93.67%,田间持效期可达30天,显著优于对照药剂73%克螨特乳油2 000倍液;48%联苯肼酯悬浮剂2 000、3 000、4 000倍液对山楂叶螨和苹果全爪螨的速效性也较好,药后3天防效均在77%以上,同时持效期可达30天,与当地常用药剂25%三唑锡可湿性粉剂1 500倍液防效相当。48%联苯肼酯悬浮剂是防治3种苹果害螨的理想药剂,生产上推荐使用浓度为3 000~4 000倍液。
A field experiment was conducted to evaluate the control effect of 48% bifenazate suspension on apple pests, apple mites, two-spotted spider mites and hawthorn spider mites. The results showed that the 48% Bifizinazole suspension 2 000,3 000,4000 times the two spotted spider mite quick good, three days after the drug control effect was 92.51% ~ 93.67% field persistence can be Up to 30 days, which was significantly better than that of the control drug 73% propargyl 2 000 times; and the rate of 2 000, 3 000 and 4 000 times 48% Also better, three days after the drug control effects are above 77%, while the persistence of up to 30 days, and local commonly used agents 25% azadirachtin WP 1 500 times the liquid control effect. 48% Bifizinazole Suspension is the ideal medicine for controlling 3 kinds of apple pests. The recommended concentration is 3 000 ~ 4 000 times.
