Title: [In vitro tests of the antagonistic behavior of Trichoderma spp. against pathogenic species of the horticultural region of La Plata, Argentina].
Abstract: The antagonistic properties of seven Trichoderma species in front of the pathogens Fusarium oxysporum, F. equiseti, F. solani, Sclerotinia sclerotiorum, S. minor, Rhizoctonia sp. and Sclerotium rolfsii was evaluated in vitro. Those microorganisms were isolated from horticultural soils of La Plata in order to test the antagonistic-pathogenic relationship. Dual cultures on PDA 2% were used. All the species of Trichoderma grew in the culture medium with a colonization value higher than 50%. Differences in the antagonistic behaviour of the pathogens were observed depending on the species with which they interacted. The presence of diffusible metabolites to the medium was demonstrated in almost 80% of the pathogens antagonists tested.
