An analytical method of chlorfenapyr·chlorantraniliprole 30％SC was established by HPLC.Chlorfenapyr and chlorantraniliprole were determined on stainless steel column C i8,using methanol+water(volume ratio of 80∶20)as the mobile phase,at the wavelength of 254 nm.The results showed that the linear correlation coefficients of chlorfenapyr and chlorantraniliprole were 0.999 5 and 0.999 2,the standard deviations were 0.02 and 0.02,the relative standard deviations were 0.1％and 0.2％,and the average recoveries were 99.64％and 99.31％,respectively.The method was simple and rapid,with high accuracy and precision,good linear correlation.It could be used for the quantitative analysis of chlorfenapyr and chlorantraniliprole in compound products.
