Thiophanate-methyl
Under aerobic conditions, thiophanate-methyl was rapidly degraded, with a half-life between less than a day and three days. Thiophanate-methyl was mineralised to a small extent. Eight metabolites were identified of which Carbendazim (MBC), 2-AB and CM-0237 (M2) were accounted as major metabolites. Carbendazim was further degraded with a half-life between 10 and 40 days. 2-AB, which was formed out of the minor metabolite DX-105, was faster degraded with a half-life between 5 and 25 days. The evaluation of one other metabolite, namely CM-0237 (M2), showed that it was even slower degraded with a half-life between 50 and 90 days. Carbendazim (MBC), one of the major products of thiophanate-methyl, is also a very active ingredient itself and was evaluated by an own dossier. Metabolites that are not drawn as part of the pathway, have been observed in degradation studies but have not been included in any suggested pathways.
