A method for separation and quantitative analysis of cyflumetofen·bifenazate 40％SC by GC was established.Detection was performed using Agilent HP-1 capillary column and FID detector,with dioctyl sebacate as the internal standard.The results showed that the linear correlation coeffiicients of cyflumetofen and bifenazate were 0.999 5 and 0.999 5,the standard deviations were 0.051 5 and 0.114 5,the relative standard deviations were 0.34％and 0.45％,the average recoveries were 99.98％and 99.81％,respectively.The method was simple,rapid,accurate,and applicable to the qualitative and quantitiative analysis of cyflumetofen and bifenazate.
