20%氟啶虫酰胺SC配方的研制

Formulation Preparation of Flonicamid 20% SC

通过试验优化得到20%氟啶虫酰胺悬浮剂的最佳配方。20%氟啶虫酰胺悬浮剂配方为:氟啶虫酰胺20%、CF20S 2.0%、500LQ 1.0%、A788 1.0%、IP 1.0%、丙二醇4.0%、黄原胶0.2%、硅酸镁铝1.0%、防腐剂0.1%、有机硅消泡剂0.2%,水补足至100%。该悬浮剂热贮和冷贮后无分层、析晶及结块等现象,分解率和悬浮率均合格,产品其它指标符合悬浮剂的要求。室内生测和田间试验结果表明,该悬浮剂对苹果树蚜虫具有较好的速效性和持效性。

The preparation of flonicamid 20% SC was studied by optimizing the additives. The formula consisted of flonicamid 20%, CF20S 2.0%, 500LQ 1.0%, A788 1.0%, IP 1.0%, propylene glycol 4.0%, xanthan gum 0.2%, magnesium aluminium silicate 1.0%, preservative 0.1%, organicsilicon defoamer 0.2%, the water making up to 100%. The thermal storage and cold storage stabilities of the SC were qualified, and it had good decomposition rate and suspension rate. In addition, flonicamid 20% SC had quick-acting efficacy and long-lasting efficacy on apple aphids.
