Abstract

A method for the direct determination of bensulfuron,acetochlor in the composite herbicide by HPLC has been described.DIKMA-Diamonsil C18 column(250×4.6mm,5μm)was used with the mobile phase of methanol and water(80∶20,V/V),the wavelength was at 230nm,and the flow rate was 1.0mL/min.Linear regression coefficient was 0.9999,Quantification was carried out with the two external standards.The average recovery was 99.29% with RSD= 0.71% for bensulfuron,100.24% with RSD= 0.73% for.acetochlor.The method was accurate,rapid.and reproducible and can be used for the quality control for 20% bensulfuronacetochlor composite herbicide.
