Pesticide Residues and Their Metabolites in Grapes and Wines from Conventional and Organic Farming System.

ABSTRACT: In this study, the occurrence of pesticide residues and their metabolites in grapes and wines was investigated. A targeted analysis of 406 pesticide residues in 49 wine and grape samples from organic and conventional production were performed using the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction method, followed by ultra-high-performance liquid chromatography coupled with tandem mass spectrometry. Multiple residues (>4 residues/sample) were detected in 22 tested samples. The most commonly detected residues were fungicides (e.g., boscalid) and insecticides (e.g., methoxyfenozide). An ultra-high-performance liquid chromatography-high resolution mass spectrometry method (UHPLC-(HR)MS) was used for screening of pesticide metabolites. We also provide a method and databa
