As a result of the mycological analysis of vervein seeds, 17 fungi species were identified. They included typical saprobiotic ones, namely Aspergillus, Penicillium, Rhizopus, Trichothecium and pathogens such as Altenaria, Botrytis, Fusarium, Rhizoctonia. Fungi frome the genera Altenaria, Fusarium and Botrytis cinerea constituted the highest proportion. In in vitro study the following fungi were the most pathogenic towards vervein seedlings: A. alternata, F. oxysporum, F. culmorum, B. cinerea and R. solani. The results showed that in vitro conditions the growth and development of A. alternata and
F. oxysporum were most effectively inhibited by Zaprawa Funaben T and Captan suspension, whereas Topsin M was much less effective and in the case of fungus A. alternata it even stimulated the development of mycelium.
