五十年代中期以来,国外发展起一组新的农药,它们的作用基团是甲基氨基甲酸根,与其他基团(R)结合成各种不同的甲基氨基甲酸酯这一类农药统称甲基氨基甲酸酯类化合物。它们的杀虫作用机理和有机磷农药相似,应用范围大致可以和有机磷农药相媲美。但与之相比,却具有高效、低毒、低积累的优点。因此进入六十年代,有一个大发展,在棉花虫害防治工作中得到普遍应用。 Since the mid-1950s, a new group of pesticides has been developed abroad. Their active groups are methylcarbamates, which combine with other groups (R) to form various methyl carbamates Collectively referred to as methyl carbamate compounds. Their mechanism of insecticidal action and organophosphate pesticides similar to the scope of application can be roughly comparable to organophosphorus pesticides. However, compared with it, it has the advantages of high efficiency, low toxicity and low accumulation. So into the sixties, there is a big development, in the cotton pest control work has been widely used.
