The invention relates to a gas chromatography-mass spectrometry rapid determination method for non-registered components in a pesticide preparation, and belongs to the technical field of pesticide quality detection. The gas chromatography-mass spectrometry rapid determination method for the non-registered components in the pesticide preparation comprises the following steps of preparing a standardsolution; preparing a sample solution; preparing a blank solution; performing GC-MS detection: injecting the standard working solution and the blank solution into a GC-MS, performing selected ion monitoring, and performing regression analysis on the corresponding concentrations of the non-registered components by the quantitative ion peak areas of the non-registered components after blank deduction, so as to obtain a standard working curve; and injecting a to-be-detected sample solution into the GC-MS under the same condition, obtaining the quantitative ion peak areas of the non-registered components in the sample af
