Summary

An improved analytical method for determining the fungicide dimethomorph in vegetables is described. The method involved single extraction with dichloromethane followed by gas chromatography-tandem mass spectrometry (GC-MS/MS) determination. The average recovery rates from vegetable samples spiked with dimethomorph at 10 and 100 μg kg−1 (n = 5) ranged between 81 and 96% and with associated relative standard deviations ≤9%. The limits of detection (LOD) and limits of quantification (LOQ) were below 10 μg kg−1 for the three studied matrices, i.e., tomato, cucumber, and onion. Successful application of the method to the analysis of samples with incurred dimethomorph residues has been demonstrated.
