Description Abstract            Triazole and pyrethroid are two of the most commonly used pesticides in vegetable cultivation recently. In this study, a multi-residue analytical method employing gas chromatography – mass spectromety (GC-MS) technique was successfully developed for quantification of two triazole fungicides including propiconaozle and difenoconazole and on pyrethroid insecticide cypermethrin (including 04 isomeres) in mustard greens. The GC-MS running program performed good separation, low detection limit and short analysis time (24 minutes). Target compounds in mustard green sample were ultrasonically extracted in 15 minutes by 60 mL acetone, followed by clean-up steps using solid phase extraction of packed activated carbon column with 40 mL acetone:toluene (v:v, 1:1) for elutions, and florisil cartridge with an elution mixture of 15 mL acetone:n-hexane (v:v, 1:5). The method was validated before applying for a preliminary screening of triazole and pyrethroid residue levels in mustard greens collected in Phu Yen Province, Vietnam.Keywords: triazole, pyrethroid, residues in vegetables, GC-MS
