ABSTRACT
Many species of genus Trichoderma are used as an important source of biological agents.The potential efficiency of Trichoderma against the pathogenic fungi like Fusarium oxysporum and Aspergillus niger was evaluated on the fungal growth by cultural pattern in which radial growth extension rates were analysed. Isolation of Trischoderma spp. was made by the serial dilution technique of the soil sample. After 72 to 96 hour later, colonies of Trichoderma were seen on Petri dishes. The radial growth of experimental fungi viz. A. niger (66.24%) and F. oxysporum (52.4%) were inhibited by Trichoderma spp. due to secretion of antifungal compound and the nature of mycoparasitism, antibiosis and competition with tested fungi.
