我国科学家首次利用除虫菊成功地开发出无公害生物农药。 目前,社会上使用的杀虫药多半是化学合成品,由于它们对人毒性很大,部分已禁用或限制使用。而天然除虫菊的加工产品是除虫效果很好的无公害生物农药。
Chinese scientists for the first time using pyrethrum successfully developed pollution-free biological pesticides. At present, most of the pesticides used in the society are chemical syntheses, which have been banned or restricted due to their high toxicity to humans. The natural pyrethrum processed products are very good pest control pollution-free biological pesticides.
