Members of the genus Trichoderma are wide-spread saprophytic fungi living in the soil and the rhizosphere of different plants. Due to their enzyme production abilities they are able to use complex biomolecules as carbon and nitrogen source. Many strains with very good biocontrol abilities against plant pathogenic fungi could be isolated from soils of agricultural areas. In this study we isolated Trichoderma strains from the rhizosphere of vegetables (pepper and lettuce) derived from gardens of different Hungarian cities (Szolnok, Kalocsa, Újszilvás, Kelebia). The isolates were identified by the sequence analysis of the ITS (internal transcribed spacer) region. The strains belonging to species that are not pathogenic to humans or cultivated mushrooms and possessing promising bicontrol potential were further investigated. The antagonistic abilities of the strains were studied against Botrytis species (B. cinerea, B. pseudocinerea) in in vitro confrontation tests and the extracellular enzyme systems of the strains were investigated in different liquid media. The knowledge of the correlation between the in vitro antagonistic abilities and enzyme production may contribute to our understanding of the biocontrol mechanism.
