Strain Tri1 showed the highest antagonistic activity against Botrytis sp. 68 78 Fusarium sp. 86 82 Mucor sp. 70 20 Tri2 Tri3 were the best antifungal strains against Rhizopus sp. 62 12 and Penicillium sp. 79 30 and Tri4 was the best antifungal strain against Aspergillus sp. 93 89 Colletotrichum sp. 93 39 . The results of four seclected strains of Trichoderma sp. showed the high conidial germination rate the fastmycelial growth on the YM-Agar medium and could produce chitinase.
