摘要
为筛选出防治苦瓜瓜实蝇的高效低毒药剂,对60%噻虫·灭蝇胺水分散粒剂、70%灭蝇胺水分散粒剂和25%噻虫嗪水分散粒剂3种杀虫剂田间药效进行了对比。试验结果表明,药后1~10 d,除60%噻虫·灭蝇胺水分散粒剂13.0 g/667 m2和25%噻虫嗪水分散粒剂8.0 g/667 m2外,其他药剂处理的防治效果均高于62.55%;但药后3~10 d,60%噻虫·灭蝇胺水分散粒剂13.0 g/667 m2防效也达到65.28%~67.64%。由此可见,60%噻虫·灭蝇胺水分散粒剂26.0 g/667 m2和60%噻虫·灭蝇胺水分散粒剂20.0 g/667 m2对苦瓜瓜实蝇的防治效果均较优于其他处理,70%灭蝇胺水分散粒剂20.0 g/667 m2的药剂效果也达到63.91%。因此,为达到防治效果,在生产中应优先使用60%噻虫·灭蝇胺水分散粒剂,其次是70%灭蝇胺水分散粒剂。
In order to screen out high-efficiency and low-toxic insecticides for controlling Bactrocera cucurbitae on bitter gourd,the field efficacy of three insecticides,namely 60%thiamethoxam-cyromazine water dispersible granule(WG),70%cyromazine WG and 25%thiamethoxam WG,were compared.The results showed that the control effects of 60%thiamethoxam-cyromazine WG 26.0 g/667 m2 and 60%thiamethoxam-cyromazine WG 20.0 g/667 m2 were better,and the control effect of 70%cyromazine WG 20.0 g/667 m2 was 63.91%.Therefore,in order to achieve the control effect,60%thiamethoxam-cyromazine WG should be used first in production,followed by 70%cyromazine WG.
