摘要
氟虫腈悬浮剂是一种高活性的广谱杀虫剂。室内试验结果表明，对小菜蛾杀伤力强，ＬＣ５０为０１０ｍｇ／ｋｇ，桃赤蚜ＬＣ５０为４０１７ｍｇ／ｋｇ，杀伤力相对较低。钵栽试验桃赤蚜持效期１５天。田间试验结果表明，氟虫腈对菜青虫、斜纹夜蛾作用迅速，以１５ｇ／６６７ｍ２施药，药后１天防效８５％以上，药后３天１００％，持效期３０天。
Fipronil SC is a high active broad-spectrum insecticide.Experimental result showed fipronil was the most toxic to Plutella xylostella L.and less toxic to Myzus persicae S. LC 50 were 0.10 mg/kg and 40.17mg/kg respectively.Effective remaining date was 15 d to Myzus persicas S.Result of field trial was that effect of fipronil was very rapid to Pieris rapae L.and Spodoptera litura F.with effect more than 85% after 1 d and 100% after 3 d at rate of 22.5g/ha.Effective remaining date was 30 d.
