INTRODUCTION
Trichoderma species are one of the most frequently isolated conidial fungi which belongs to the division Ascomycota, Class Sordariomycetes, Order Hypocreales and Family Hypocreaceae. They have been isolated from a diverse range of natural and artificial substrata, which demonstrates their high opportunistic potential and adaptability to various ecological conditions (Druzhinina et al., 2011). They are free living fungi which are highly interactive in root, soil and folior environments.
