Objective. To evaluate the antagonistic capacity of basidiomycetes against relevant phytopathogens in vitro, in search of strains with antagonistic capacity. Methods. In the present study, antagonism assays were conducted in eight culture media differing in carbon and nitrogen sources, mineral salts, and vitamins. Results. Qualitative and quantitative observations demonstrated antibiosis by H. erinaceus and T. versicolor, which exhibited marked mycoparasitism against all phytopathogenic species tested, whereas Ganoderma showed limited in vitro antagonism. Conclusion. These findings highlight the utility of antagonism assays as a bioprospecting tool for screening and identifying basidiomycetes with controlled potential against fungal phytopathogens.
