[Methods] The separation and quantitative analysis of bromoxynil octanoate, nicosulfuron and atrazine were conducted by HPLC with UV detector with acetonitrile and water as the mobile phase, the ODS C18 column as fix phase at 238 nm. [Results] The linear correlation coefficients for bromoxynil octanoate, nicosulfuronand atrazine were 0.9997, 0.9998 and 0.9997; the standard deviations were 0.085, 0.009 and 0.095; the variation coefficients were 0.64, 0.28 and 0.43%; the average recoveries were 101.42, 100.00 and 98.82%, respectively. [Conclusions] The method is simple, rapid, accurate, which is suitable for the qualitative and quantitative analysis of bromoxynil octanoate,
