摘要: 为明确20%呋虫胺SG(护瑞)对水稻褐飞虱[Nilaparvata lugens (Stal)]的田间防效以及施用剂量,采用笼罩法进行稻苗叶面喷雾,调查药后2~7 d 20%呋虫胺可溶粒剂(SG)对褐飞虱的防效。结果表明,20%呋虫胺SG在施用制剂量为60~600 g/hm2时,其防效与25%噻虫嗪水分散粒剂(WG)60~120 g/hm2基本相当,优于50%吡蚜酮SG 300~600 g/hm2和10%吡虫啉可湿性粉剂(WP)300~600 g/hm2的防效。田间施用20%呋虫胺SG推荐剂量为60 g/hm2

Abstract: Aiming to determine the field control effect and dosage of 20% dinotefuran SG on rice brown planthopper [Nilaparvata lugens (Stal)], spraying the leaves of rice seedlings by cage method, the control effects of 20% dinotefuran SG against rice brown planthopper after the drug 2~7 days was investigated. The control effects of 20% dinotefuran SG at the concentration of 60~600 g/hm2 were similar to that of 25% thiamethoxam WG 60~120 g/hm2, which were better than that of 50% pymetrozine SG 300~600 g/hm2 and 10% imidacloprid WP 300~600 g/hm2. The recommended dosage of 20% dinotefuran SG was 60 g/hm2 in the field.

Key words: dinotefuran, brown planthopper[Nilaparvata lugens (Stal)], caged test, control effects
