[目的]筛选出适合设施大棚防治辣椒蚜虫的药剂。[方法]采用显微镜鉴定辣椒蚜虫种类后,将5种药剂叶面喷雾后调查其防效。[结果]设施大棚辣椒中的蚜虫包括棉蚜、桃蚜和萝卜蚜。25%吡蚜酮WP 75.0 g a.i./hm2和5%啶虫脒WP 30.0 g a.i./hm2对辣椒蚜虫防效较好,均在84.21%以上;77.5%敌敌畏EC 581.3 g a.i./hm2防效次之;18 g/L阿维菌素EC 1.5 g a.i./hm2药后7、12 d的防效显著下降和25 g/L高效氯氟氰菊酯EC 15.0 g a.i./hm2防效相当。[结论]吡蚜酮和啶虫脒能有效防治设施大棚辣椒蚜虫且对辣椒生长安全。
[Objective] The research aimed to screen out the suitable pesticide for greenhouse pepper aphid. [Method] After identifying the species of pepper aphid by microscope, the leaf surface of 5 kinds of medicaments were sprayed to investigate the control effect. [Result] The aphids in greenhouse pepper include aphid, green peach aphid and radish aphid. 25% pymetrozine WP 75.0 g ai / hm2 and 5% acetamiprid WP 30.0 g ai / hm2 were better than pepper aphids, all above 84.21%; 77.5% dichlorvos EC 581.3 g ai / hm2 The control efficacy of 18 g / L avermectin EC 1.5 g ai / hm2 at 7 and 12 d was significantly lower than that of 25 g / L lambda-cyhalothrin EC 15.0 g ai / hm2. [Conclusion] Pymetrozine and acetamiprid were effective in controlling greenhouse pepper aphids and their growth was safe.
