我们于1990年开始对唇形科植物LSL草抽提物进行研究,结果表明:LSL草甲醇抽提物对桃蚜、柑桔全爪螨具有很强的触杀作用和拒食效应;其1000倍液作用于桃蚜、柑桔全爪螨防除效果均在90％以上。LSL草是制造杀虫、杀螨剂的理想原料。目前用于防除蔬菜上常见且难防的桃蚜,只有乐果和拟除虫菊酯类农药,但前者毒性高,后者抗性强。另外,迄今为止我国登记 We started in 1990 on the Labiatae LSL grass extracts studied, the results showed that: LSL methanol extract of Myzus persicae, citrus red mite has a strong contact effect and antifeedant effect; its 1000 times the liquid Effect on the Myzus persicae, Citrus red mite control effect are more than 90%. LSL grass is to create insecticide, acaricide ideal raw materials. Currently used to control vegetables common and difficult to prevent Myzus persicae, only dimethoate and pyrethroid pesticides, but the former high toxicity, the latter resistance. In addition, our country has so far registered
