We developed the method for Bifenazate diazene for vitalization of export of domestic agricultural products. Korea’s major exporting countries are U.S.A, Japan, Hongkong and so on. These countries enforce Positive list system or Zero tolerance as one of technical barriers in trade. Residue definition of Bifenazate in Korea is the only bifenazate. But residue definition for bifenazate in several countries is bifenazate as the sum of bifenazate and its metabolite, bifenazate diazine. So this should be taken into account when analyzed. Our multiresidue method has been using mass spectrometry, and bifenazate was analyzed by the multiresidue method with GC-MS/MS in our previous study. To efficiently analyze bifenazate and its metabolite at once, we used the multiresidue method with GC-MS/MS. In the step of QuEChERS extraction added an analytes protectant(AP), Bifenazate diazine is converted to bifenazate. A method for Bifenazate diazine has been developed using the QuEChERS EN method with gas chromatography-tandem mass spectrometry (GC-MS/MS) in 5 agricultural commodities (Apple, Paprika. Pear, Strawberry, and Tomato). To validate the method developed, all commodities were spiked with two concentration levels of 10 and 100 μg/kg. The recoveries were within 70~120% with the relative standard deviation (RSD) of 10%, and the limit of quantification (LOQ) of methods was below 10 μg/kg, and the correlation coefficients (R2) of matrix-matched standards were > 0.99. The recoveries, LOQ, and repeatability achieved, meet the criteria of tolerance level monitoring of these pesticides in the agricultural export product.
