杀虫双和杀螟丹均属沙蚕毒素(Nereistoxin)的衍生物,杀虫双是贵州省化工研究所1974年在研制杀螟丹的基础上而合成杀螟丹的中间体——双钠盐及单钠盐,通过药效试验发现它具有与杀螟丹类似的杀虫效果,1977年完成中试鉴定,肯定了杀虫双为高效低毒的杀虫剂,是我国在应用上开发的一个农药新品种,现已推向工业化生产。为了
Both insecticidal double and cartap are Nereistoxin derivatives, insecticidal double is the Guizhou Institute of Chemical Technology in 1974 on the development of Cartap foundation on the basis of synthetic cartap chitosan intermediate - disodium Salt and monosodium salt, it is found through the efficacy test that it has a similar insecticidal effect with cartap. In 1977, the pilot test was completed, confirming that insecticide is an insecticide with high efficiency and low toxicity, and is developed in China A new pesticide species, has now been pushed to industrial production. in order to
