The analysis method of azoxystrobin·fluazinam 50% suspension concentrate (SC) was studied.The analysis was conducted with HPLC, using a C18 reversed-phase column and a variable wavelength UV detector, methanol and water (volume ratio of 3︰7) as mobile phase, and the effective components were analyzed and quantified by external standard method. The standard deviations, variation coefficient and average recovery of the method were 0.17, 0.82%, 99.7% and 0.18, 0.61%, 99.5% for azoxystrobin and fluazinam respectively. The method is convenience, fast, precise and accurate.
