A method for determining residues of ‘Alar’ (B‐995) in apples has been developed. It is based on the alkaline hydrolysis of ‘Alar’ to yield unsymmetrical dimethylhydrazine. the latter is oxidised by selenium dioxide to yield formaldehyde which is determined colorimetrically using 2‐hydrazinobenzothiazole.
