Azoxystrobin and trifloxystrobin have been determined in apples by a gas chromatographic method with micro-electron capture detection (μ-ECD). Pesticides were isolated by matrix solid-phase dispersion. Reco-veries from fortified samples ranged from 70 to 100%. Limits of determi-nation were 0.02 mg kg-1 for azoxystrobin and 0.01 mg kg-1 for trifloxy-strobin.

This paper describes a simple gas chromatographic method with nitrogen-phosphorus detection for determination of residues of the fungi-cides cyprodinil and pyrimethanil in apples. Two extraction techniques were compared, liquid-liquid extraction and column extraction. Recovery from fortified apples by use of either of these extraction techniques was 82-102% for both fungicides. Limits of determination for cyprodinil and pyrimetha-nil in apples after liquid-liquid extraction were 0.05 and 0.02 mg kg-1, respectively; the values were 0.1 and 0.04 mg kg-1, respectively, when column extraction was used.
