Fungal Strains

Trichoderma fungal strains include a wide range of evolutionary solutions ranging from highly efficient soil colonizers with high biodegradation potential to non-strict plant symbiotes that colonize the rhizosphere. Certain groups of biotypes within this conglomerate are capable of antagonizing phytopathogenic fungi by using colonization of the substrate, antibiosis and / or mycoparasitism as main mechanisms. This antagonistic potential is the basis of effective applications of different strains of Trichoderma as an alternative to chemical control against a wide range of pathogens of fungal plants (Chet 1987; Harman and Björkman 1998). Due to the diversity of the activities of the conglomerate of the Trichoderma strain, a wide range of applications has been developed: the antagonistic potential is the basis of effective control of a wide range of phytopathogenic fungi and the biodegradative capacity is a source. useful enzymes in different industrial sectors (Harman and Kubicek 1998). Biological control strains against Trichoderma have developed many mechanisms to attack other fungi and improve the growth of plants and roots (Harman 2000). Colonization of the root system by strains of Trichoderma competent in the rhizosphere leads to increased development of the root and / or aerial systems and crop yields (Harman and Kubicek 1998). Other activities, such as the induction of systemic plant resistance and antagonistic effects on phytopathogenic nematodes (Sharon et al. 2001), have also been described. These facts strongly suggest that during plant-Trichoderma interactions, the fungus actively participates in the protection and improvement of its ecological niche.
