A method for simultaneous monitoring of five benzimidazole fungicides in soil by QuEChERS-ultra-high performance liquid chromatography and mass spectrometry was developed.The five benzomidazole fungicides had good linearity in the range of 5.00～400μg·L-1 with correlation coefficients greater than 0.9990.The detection limits were 0.03～0.11 μg·kg-1,and the recoveries ranged from 87.4％to 104.5％with relative standard deviations less than 5％for the three concentration levels.The method has the advantages of simple and rapid pretreatment,low consumption of organic reagents,high sensitivity,accurate and reliable test results,and is suitable for simultaneous analysis of 5 benzimidazole fungicides in soil.
