The subject of the studies concerned pathogenic fungi (Alternaria alternata 17, Ascochyta pisi 31, Botrytis cinerea 19, Fusarium culmorum 44. F. oxysporum f. sp. glycines 37, F. oxysporum f. sp. phaseoli 51, F. oxysporum f. sp. pisi 33, F. solani 25, Phoma exigua var. exigua 11, Pythium irregulare 34, Rhizoctonia solani 64, Sclerotinia scelerotiorum 15) and biopreparations, i. e. Biosept 33 SL, Biochikol 020 PC, Polyversum as well as Zaprawa Oxafun T. The studies were conducted in vitro conditions, considering 6 repetitions (dishes) for each experimental combinations. After 10 days the diameter of the fungus colonies' growth was measured and morphological changes in the appearance of fungi cultures were observed. Addition of the medium of biopreparations and Zaprawa Oxafun T caused inhibition of the growth and development of pathogenic fungi. The most effective preparation which inhibited the growth of the colonies was Biosept 33 SL. Biopreparations as well as Zaprawa Oxafun T caused inhibition of the formation of air mycelium, sporules and sclerotia
