The aim was to study the antagonistic interactions between microscopic fungi that often contaminate plasterboard, and test cultures which recommended determining the fungus resistance. Methods. Determination of interactions between test-cultures and strains isolated from plasterboard was carried out by agar block method. Results. The isolated from plasterboard Alternaria infectoria F-41218 E.G. Simmons, Aspergillus favipes F-41213 (Bain. & Sart.) Thom & Church, Chaetomium globosum F-41224 Kunze ex Fr., Stachybotrys chartarum F-41215 (Ehrenb.) S. Hughes strains inhibited the growth of test-cultures, recommended for study fungal resistance. Antagonistic activity of isolated from plasterboard fungi against the test-cultures increased in order Alternaria infectoria F-41218 < Aspergillus favipes F-41213 < Stachybotrys chartarum F-41215 < Chaetomium globosum F-41224. It was shown that the increase of antagonistic activity of isolated from plasterboard cultures and changing of interaction categories to complete inhibition of test-culture growth on medium with plasterboard. Conclusion. Thus, C. globosum F-41224 isolated from plasterboard was the strongest antagonist, as evidenced by the prevalence of inhibition, fungistatical and fungicidal effects against the test-cultures.

Key words: antagonistic properties, microscopic fungi, fungistatical and fungicidal effects, plasterboard.
