Bifenthrin is a pyrethroid insecticide used primarily against the red imported fire ant by influencing its nervous system. It has a high toxicity to aquatic organisms. Although it is listed as a restricted use chemical in the United States, it is allowed to be sold for daily use, provided the product sold has a low concentration of bifenthrin. The chemical was discovered and developed by FMC Corporation. Products containing bifenthrin include Transport, Talstar, Maxxthor, Capture, Brigade, Bifenthrine, Ortho Home Defense Max, Bifen IT, Bifen L/P, Torant, Zipak, Scotts LawnPro Step 3, Wisdom TC Flowable, FMC 54800, Allectus, Ortho Max Pro and OMS3024 and mega wash from green planet.

生产方法
制备方法一由2-苯基苯甲酸与SOCl2反应制得2-苯基苯甲酰氯,再与二甲基甲酰胺反应制得相应的2-苯基苯甲酰胺,经氢化锂铝还原制得2-苯基二甲苄胺。将2-苯基二甲苄胺与CH3I反应制得相应的铵盐,再经异构化后与氯甲酸乙酯反应,制得2-甲基-3-苯基氯苄。最后与相应的酸在KOH存在下,于乙腈中回流16h,制得联苯菊酯。 为拟除虫菊酯类杀虫剂，防治棉铃虫,棉红蜘蛛,桃小食心虫,梨小食心虫,山楂叶螨、柑桔红蜘蛛,黄斑蝽,茶翅蝽,菜蚜,菜青虫,小菜蛾,茄子红蜘蛛,茶细蛾等20多种害虫,温室白粉虱、茶尺蠖、茶毛虫。
