在寻求改进生物活性的途径时,常常使用氟取代氢或氯。这种取代方式可以大大提高农药的药效,在拟除虫菊酯结构中引进氟原子,会提高对害虫的药效,并且有杀螨作用,因此含氟拟除虫菊酯已被农药行业人士所关注。还有例如:氟乐 In seeking ways to improve bioactivity, fluorine is often used to replace hydrogen or chlorine. This substitution method can greatly improve the efficacy of pesticides, the introduction of fluorine atoms in the pyrethroid structure, will increase the efficacy of pests and have acaricidal effect, the fluorine-containing pyrethroid has been the concern of the pesticide industry.
