Abstract: The genus Trichoderma is cosmopolitan in soils, wood decomposition and plant material. Species of Trichoderma are often dominant components of the soil microflora in various habitats. This is due to different metabolic capacity of the Trichoderma species and its aggressive competitiveness in nature. The genus Trichoderma are frequently used in biological control because of its antagonist ability of phytopathogenic fungi. The mechanisms employed by Trichoderma spp. to antagonize other fungi are competition (for space and / or nutrients), antibiosis and microparasites, while in the latter case, involved lytic enzymes such as proteases, glucanases, chitinases and lipases. Some of these proteins have a large agricultural potential, especially as active components of new formulations of fungicides. Trichoderma harzianum Rifai (Ascomycota, Hypocreales, Hypocreaceae) is a filamentous fungus, asexual, commonly isolated of tropical soil of plant material, rhizosphere ecosystems and decomposing organic material a ratio of 101-103 spores per gram of soil (Figure 1).
