Abstract

Trichoderma spp. are long-time known antagonists of fungal plant pathogens and probably the most widely-employed biological fungicides worldwide. Much is known about the mode of action of antagonistic Trichoderma strains against different plant pathogens and the mechanisms of regulation of the antagonistic activity. Considerable progress has been made with regard to understanding plant-Trichoderma interaction, casting a new light on the complex relationships among plant, pathogen and antagonist. The advancements in biomass production and formulation have allowed to obtain products that are less expensive, more durable and more effective than in the past, bridging the gap between chemical control and biocontrol with Trichoderma in terms of efficacy and reliability and making some strains of Trichoderma the most successful biological fungicides so far.In spite of this, the potential of Trichodema spp. for protection of crops from biological and abiological constraints, do not appears to be completely disclosed and exploited. Recent findings have shown the potential of some Trichoderma for biological control of insect pests. Some Trichoderma are source of bioactive metabolites that have unexpected and quite interesting activities. From cultures of T. citrinoviride we have isolated and characterized secondary metabolites that have fagodeterrent effect against aphids (PCT patent filed), insect pests of great economic importance for agriculture and one of the main causes of loss of agricultural produce and reduction of its quality.Also, some Trichoderma strains have shown the capability of to control plant parasitic nematodes. We have investigated the capability of our reference biocontrol strain T. harzianum ITEM 908 to protect tomato plants from the attack of the root-knot nematode Meloidogyne incognita. The presence of T. harzianum ITEM 908 in soil reduces all the infestation parameters of M. incognita, such as egg mass production, female fecundity and reproduction potential, on the infested tomato roots. In addition, T. harzianum ITEM 908 is able to induce resistance to M. incognita in tomato. These results open up interesting opportunities for both research and development of new Trichoderma-based products.
