Isolates of Ophiostoma ulmi with mutations conferring high or low levels of tolerance to MBC‐generating fungicides were selected in the laboratory. Comparisons between these tolerant forms and their wild type equivalents indicated that the acquisition of a mutation in the tol locus was associated with decreased growth on agar medium. Pathogenicity and bark‐colonizing ability were also found to be significantly reduced, indicating that the fitness of tolerant individuals was impaired.
