Several Trichoderma spp. are used as biocontrol agents because they can reduce the disease severity in plants by inhibiting pathogens through different mechanism of action. Fusarium oxysporum (FO) y Botrytis cinerea (BC) are economically relevant fungi since they cause important losses in more than 200 crops worldwide.To analyse the antagonistic potential of Trichoderma against these two pathogens, we used 6 strains from different species, representing the genetic diversity existing in this genus, and different in vitro assays performed in two culture media (PDA y MM). The mycoparasitic ability and antifungal activity of volatiles and metabolites secreted by Trichoderma were tested. Trichoderma parareesei T6 showed the highest mycoparsitism against FO on PDA. Volatiles produced by these six strains on MM cultures reduced the FO growth in ca. 50-60% without significant differences among strains, but they had not activity against BC. The secreted metabolites of T. virens T87 on PDA or MM showed the highest growth inhibition values in both pathogens.These results indicate that the biocontrol potential of Trichoderma spp. depends on the genotype, the target pathogen and the culture conditions.
