The presence of degradation products of bromopropylate, trichlorphon, parathion‐methyl and tebuconazole in white and red wines elaborated from musts spiked with commercial formulations of the pesticides was studied. Must and wine were subjected to solid‐phase extraction followed by gas chromatography with electron ionization mass spectrometric detection. α ‐Bromophenylphenylmethanol, aminoparathion, acetylaminoparathion‐oxon and dichlorvos have been identified as degradation products of bromopropylate, parathion‐methyl and trichlorphon in wines, respectively. Moreover, the presence of additives and impurities of the formulations in elaborated wines has also been found. Copyright © 2004 John Wiley & Sons, Ltd.
