Abstract[Objective]Ultraperformance liquidchromatography（UPLC）triplequadrupole masspectrometry（TQMS）wasestablished for thedeterminationofcarbendazim，metrbuzinandpropiconazoleresiduesinsoil.Mthod]hetargetwasextractedbyultrasound-ssistd （204号 0.1% acetonitrile-formic acid，separatedby ACQUITYUPLCBEH C18（2.1mm×100mm ， 1.7μm ），and scanned by multi-reaction monitoring（MRM）with the gradient elution using the mobile phase system of acetonitrile-0. 1% formic acid water in electrosprayed positive ionization （ESI+ ）mode.[Result]Thelinearityofthethree targets，carbendazim，metribuzinand propiconazole，was goodintherangeof 0.1- （20 （204号 100.0μg/L （ R2≥0.998 ），and the limits of detection （LODs）of the method were in the range of ，with RSD 0.33% （20 （204号 8.03% ，and the recoveries of spiking were in the range of 6 5.0%-105.0% ，and the relative standard deviations of the actual samples tested were ⩽4.82% .[Conclusion]Thismethodischaracterizedbyhighsensitivity，simpleoperation，lowdetectionlimit，highprecisionandaccuracy，andisitableforteteriaioofarbendaim，etrbuinndpropicoazolesiduesinsoil，hichanrovideticapport for the detection of trace pesticide residues in soil.
