The aim of this work was to isolate fungal strains from phytotoxic agricultural soils, screen them,categorize the most tolerant fungi to three fungicides, and identify them by a molecular approach.In this study, 28 fungal strains were isolated from phytotoxic agricultural soil with intensive use ofpesticides. The capacity of fungi to resist and degrade different concentrations of carbendazim,captan, and zineb was determined by an exploratory multivariate analysis. Actinomucor elegans15 LBM 239 was identified as the most tolerant fungus to these fungicides, degrading a 86.62% ofcarbendazim after 7 days of treatment. In conclusion, A. elegans LBM 239 demonstrated the highesttolerance and capacity to biodegrade carbendazim, becoming a potential candidate for bioremediation of contaminated soils with carbendazim, captan, or zineb.
