A method was developed for the determination of difenoconazole + azoxystrobin 28% FS by high-performance liquid chromatography on C18 column with a variable wavelength UV detector, using acetonitrile and water as mobile phase. The results showed that the standard deviations, variation coefficients and average recoveries of difenoconazole and azoxystrobin were 0.04, 0.50%, 99.0%and 0.09, 0.40%, 98.8%, respectively.
