In this study, a rapid, highly sensitive and selective method was developed for the simultaneous determination of residues of sulfoxaflor, pyrifluquinazon and spirotetramat in fruits(apple, grape, and strawberry) and vegetables(cucumber, onion, Chinese cabbage, spinach, and welsh onion) by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). The target compounds were extracted from the samples with acetonitrile and cleaned up with dispersive solid phase extraction using primary seco...
