AB  - A QuEChERS-liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was 
      developed for the determination of pyraclostrobin, thiophanate-methyl and its 
      metabolite carbendazim in soil and citrus. The samples were extracted with 
      methanol or acetonitrile, purified by primary secondary amine (PSA), then 
      separated by LC, detected in multiple reaction monitoring (MRM) mass spectrometry 
      mode via positive electrospray ionization. The analytes were quantified by 
      matrix-matched standard solutions with external standard method. The limits of 
      quantification (LOQs) of pyraclostrobin, thiophanate-methyl and carbendazim in 
      different matrices were 5.8-7.0 mug/kg, 9.3-14.1 mug/kg and 2.1-2.6 mug/kg, 
      respectively. For all the samples, the spiked recoveries ranged from 75.48% to 
      109.18%, and the relative standard deviations (RSDs) were 0.60%-5.11% (n=5). The 
      method is quick, easy, effective, sensitive and accurate. The matrix-matched 
      calibration solutions can efficiently compensate matrix effects of the 
      pyraclostrobin, thiophanate-methyl and carbendazim in LC-MS/MS analysis. The 
      established method can be applied to the residue analysis of the real samples of 
      soil, citrus peel, citrus pulp and citrus fruits.
