The invention relates to a method of determining the content of 29 additives in a pesticide preparation by gas chromatography-mass spectrometry, belonging to the technical field of pesticide quality detection. The method comprises steps: (1) a reference solution is prepared; (2) a sample solution is prepared; (3) a blank solution is prepared; and (4) GC-MS detection is carried out. High throughputscreening and precise determination on 29 additives in the pesticide preparation which are difficult to be simultaneously detected can be carried out at the same time, the detection efficiency is greatly improved, the method has the significant advantages of simple operation, quickness, accuracy, high sensitivity, good repeatability and the like, the content of prohibited and restricted additivesin the pesticide preparation can be quickly detected, a reliable technical support is provided for production and quality supervision of the pesticide preparation, and the sustainable development ofthe pesticide industry is e
