The aim of this work was to determine establishment of pathogenic and saprotrophic fungi in barley seeds dressed with bioproducts of different composition and mechanism of action. The following products were used for seed's dressing: Biochikol 020 PC, Biosept 33 SL, Bioczos BR, Cedomon EO, Polyversum, Biolux - New and Cropaid. Chemical seed dressings such as Funaben T and Vitavax 200 FS, employed usually in conventional agriculture, were used for comparison. Using blotting-paper method, germination energy and ability of the seeds were assessed. From the studied material, saprotrophic species (Alternaria alternata, Penicillium spp.) were mainly isolated while pathogenic ones (Fusarium avenaceum, F. poae, F. culmorum and Fusarium spp.) occurred to a lesser degree. All products applied effectively controlled an occurrence of pathogenic fungi of Fusarium genus in barley seeds
