A procedure for the determination of 23 pesticides from different classes (organophosphorus and organochlorine compounds, synthetic pyrethroids, and triazoles) in cereal crops is proposed. It is based on sample preparation according to the QuEChERS method with the subsequent cleaning of the extract with natural aluminosilicate and the determination of analytes by gas chromatography with mass-spectrometric detection. The limits of the quantitative determination of pesticides are ~0.005 mg/kg. The relative standard deviation does not exceed 0.02. The duration of analysis is 35–40 min.
