Abstract:
The dynamics of the uptake, translocation, and disappearance of thiabendazole (TBZ) and methyl-2-benzimidazolecarbamate (MBC), the fungicidal breakdown product of benomyl, were studied in tomato and pepper plants grown on nutrient solutions containing 0.5 ppm TBZ and 2.5 ppm MBC. Chemical analysis of pepper plants showed that the fungicides accumulated in the leaves only, where concentrations of 20 ppm TBZ and 60 ppm MBC were recorded. Thiabendazole was completely removed from pepper plants by acetone extraction, whereas MBC was only partially removed by acetone and the rest was weakly bound to the tissue and released by either methanolic HCl extraction or acid hydrolysis. The rate of disappearance of TBZ from pepper leaves was three to four times faster than that of MBC. Balance studies in tomatoes have shown an average disappearance rate of 13.5% per 10 days for MBC. 2-Aminobenzimidazole, the degradation product of MBC, was always detected but its concentration did not exceed 2% of that of the parent compound. © 1974.
