The invention discloses a detection method of ultra-high performance liquid chromatography-tandem mass spectrometry of ipconazole residues in maize. The detection method comprises the steps of: firstly extracting the ipconazole in the maize by utilizing an optimized QuEChERS method (purifying agents in extraction and purification steps are three kinds of PSA, C18 and GCB) with acetonitrile as an extraction solvent, and obtaining higher adding standard recovery rate; and then adopting the ultra performance liquid chromatography-tandem mass spectrometry (UPLC-ESI+-MS / MS) to detect the ipconazolein the maize. The detection method is simple, sensitive and selective, and can provide scientific techniques for safety monitoring and environmental behavior assessment of agricultural products.
