The study focused on broad bean, White Windsor cv., from a replicated field experiment conducted in 2010-2012, in which different variants of biological protection were used: Polyversum WP, Bioczos BR and Biosept 33 SL biopreparations. Altogether 2053 fungi colonies were obtained from broad bean seeds. Irrespective of applied protection, the most numerously isolated fungi: Alternaria alternata – 21.7%, came from the following genera Fusarium – 19.6% and Penicillium – 14.4% and species of Botrytis cinerea – 10.4%, Epicoccum purpurascens – 9.4% of isolates. Seeds from biologically protected treatments were characterized by quantitatively poorer fungal community (approximately 473 colonies) in comparison with the control (633). A major proportion of pathogenic species, 53.4% was found in the seeds protected with Polyversum WP formulation and in the control, among which the most frequently isolated were fungi of the genus Fusarium, B. cinerea, Epicoccum purpurascens. Foliar application: 2x and 3xBioczos BR and 1xBiosept 33 SL limited presence of pathogenic fungi (45.9%, 46.9%), but favored colonization of seeds by saprobionts represented by A. alternata, Penicillium, C. herbarum.
