Environmental fate:
148 concludes that, although benomyl is highly toxic to aquatic organisms, this effect is unlikely to be seen in the field due to the low bioavailability of sediment-bound residues. Earthworm populations may take more than two years toAnimals:In animals, the butylcarbamoyl group is removed to give the relatively stable carbendazim, followed by slow degradation to non-toxic 2-aminobenzimidazole. Hydroxylation also occurs, and the principal metabolite 5-hydroxybenzimidazole carbamate is converteSoil:Benomyl is rapidly converted to carbendazim in the environment, 50 2 and 19 h in water and in soil, respectively. Data from studies on both benomyl and carbendazim are therefore relevant for the evaluation of environmental effPlant:In plants, the butylcarbamoyl group is removed to give the relatively stable carbendazim, followed by slow degradation to non-toxic 2-aminobenzimidazole. Further degradation involves cleavage of the benzimidazole nucleus. Benomyl per se is stable -
