title: Determination of benomyl, carbendazim and 2-aminobenzimidazole (2-ab) in plant materials. Part I: Apples, red-currants, grapes, kale and sugar beets.
abstract: Benomyl and Carbendazim are widely used fungicides with systemic activity. In the Federal Republic of Germany the legal limits of Benomyl and Carbendazim lie between 0.1 and 7 ppm dependent on the substrate. A method for the determination of Benomyl and Carbendazim in apples, red-currants, grapes, kale, and sugar beets was developed. Benomyl and Carbendazim are extracted with ethyl acetate, saponified and determined as 2-aminobenzimidazole by thin-layer chromatography. The detection limits lie between 0.02--0.08 ppm, recoveries amount to 87% at 0.5-ppm levels.
