A simple and specific method is decribed for the individual determination of triadimefon and triadimenol diastereomers (-A and -B) in wheat plants and soil samples at residue levels. The quantification of the residues was made by gas chromatography with a thermionic specificity detector with a glass column (1.4 m x 2 mm i.d) packed with Carbowax 20 M coated on 125-150 mug Chromosorb. The method exhibits good recovery for the three substances at fortification levels ranging from 0.01 to 10.00 mg/kg. Recovery for all sample types is 86-114 per cent for triadimefon, 91-114 per cent for triadimenol-A and 89-109 per cent for triadimenol-B. Limits of detection and determination are 0.01 mg/kg.
