1949年美国碳素公司第一个化学合成拟除虫菊酯(丙烯菊酯)问世,在农业应用方面弥补了天然除虫菊酯(主要用于卫生害虫)的不足。经过长期试验,对多种昆虫有较高的杀虫活性,击倒快,而对哺乳动物低毒,在土壤中和动植物体内易降解为无毒物质,不会引起环境污染。进入七十年代以来,英国埃利奥特(Drelliott)博士通过对除虫菊酯化学结构的研究,在合成技术上取得了重大突破,制成了第一个具有耐光性能可广泛用于防治农业虫害的二氯苯醚菊酯,继后又研究成功了药效更高的氯氰菊酯和溴氰菊酯,并投入工业化生产。法国罗素优克公司生产的溴氰菊
In 1949, the advent of the first chemical synthetic pyrethroid (alfalfa) by the U.S. carbon company made up for the deficiencies of natural pyrethrins (mainly used for hygiene pests) in agricultural applications. After long-term test, it has high insecticidal activity against many kinds of insects, knocking down fast, low toxicity to mammals, easily degrading into non-toxic substances in the soil, plants and animals, and will not cause environmental pollution. Since the 1970s, Dr. Drelliott made a major breakthrough in the synthetic technology by studying the chemical structure of pyrethrins, and made the first one that has lightfastness and can be widely used to control agricultural pests Permethrin, followed by the successful study of more effective cypermethrin and deltamethrin, and put into industrial production.
