含氟表面活性剂在农药中的应用

当使用常规助剂(碳-氢链组成)不能发挥药剂的药效时,使用含氟表面活性剂助剂,能起到理想的效果。论述含氟表面活性剂的性能和应用,在10%啶虫脒微乳剂中加入不同助剂,进行了对蚜虫的室内毒力试验。结果表明,使用含氟表面活性剂助剂有明显增效作用;其中含氟表面活性剂OBS助剂增效作用最大(91.70%),有机硅助剂次之(87%)。当含氟表面活性剂OBS与常规助剂JFC复配使用,发挥了最大协同增效作用(96.59%),远胜于含氟表面活性剂OBS助剂单用和与其他含氟表面活性剂助剂复配使用的效果。

Application of Fluorinated Surfactant in Pesticide

When conventional adjuvants （carbon hydrogen chain） cannot have effect on the action of pesticide formulations, use of fluorinated surfactant adjuvants can have ideal effect. This article elaborates fluorinated surfactant performance and application, application of different adjuvant mixtures in 10% acetamiprid microemulsion and indoorvirulence test on aphid. Result indicated that fluorinated surfactant adjuvants and organosilicon adjuvants have obvious synergized action when use alone, and the synergized action of fluorinated surfactant fluorine adjuvants OBS is biggest （91.70%）, followed by organosilicon adjuvants （87%）. When fluorinated surfactant adjuvant OBS and conventional adjuvants JFC are used together, synergized action （96.59%） is greater than that of fluorinated surfactant adjuvant OBS and the mixture of them.
