Abstract (EN): Azoxystrobin, kresoxim-methyl, trifloxystrobin, pyraclostrobin, famoxadone and fenamidone are permitted Q Inhibitor (Q(0)I) fungicides applied to vine in some European countries for the treatment of downy and powdery mildews. In this work, a method is validated for the analysis of these fungicides in grapes and wine. This screening method consists in a simple one step liquid-liquid extraction followed by liquid chromatography (LC) fitted with a diode array detector (DAD). Limits of detection for grapes and wine were below 0.2 mg kg(-1) or mg l(-1), precision was not above 13%, and recoveries were, on average, 95 +/- 5% for grapes and 104 +/- 6% for wine. Global uncertainties evaluated in the concentration range from 0.25 to 2.50 mg l(-1) were below 20%. A confirmatory method by gas chromatography (GC) with mass spectrometry (MS) detection was used.
