AB  - A method was developed for the determination of pyriminobac-methyl and 
      bispyribac-sodium residues in rice by liquid chromatography-tandem mass 
      spectrometry (LC-MS/MS) coupled with modified QuEChERS. The samples were 
      extracted with acidified acetonitrile, and then purified by octadecylsilane 
      bonded silica (C(18)) adsorbents. The analytes were separated on a ZORBAX SB 
      C(18) column through a gradient elution using 0.1% (v/v) aqueous formic acid 
      aqueous containing 5 mmol/L ammonium acetate and acetonitrile as mobile phases. 
      Positive electrospray ionization (ESI(+)) was used. Qualitative work was 
      performed using selected dynamic multiple reaction monitoring (dynamic MRM) mode. 
      Quantization was performed using external standard method. The results showed 
      good linearities of pyriminobac-methyl and bispyribac-sodium with correlation 
      coefficients (r(2)) not less than 0.996. The limits of detection (LODs) of the 
      method were 0.8 mu g/kg for pyriminobac-methyl, and 3 mu g/kg for 
      bispyribac-sodium. The mean spiked recoveries of pyriminobac-methyl and 
      bispyribac-sodium at three spiked levels were 76.6%-85.6% and 73.0%-86.7%, 
      respectively, and the relative standard deviations (RSDs) of pyriminobac-methyl 
      and bispyribac-sodium were 0.9%-3.4% and 1.2%-5.5%, respectively. This method is 
      simple, rapid, sensitive, and suitable for the simultaneous determination of 
      pyriminobac-methyl and bispyribac-sodium in rice.
