In vitro antagonistic effect of different strains of 4 Trichoderma sp. namely T. harzianum, T. viride and T. atroviride and T. hamatum were evaluated against pathogenic fungi isolated from Nopal vegetable crops in San Sebastian Villanueva region Puebla, Mexico. The pathogenic fungi were Pythium sp., Fusarium sp. and Colletotrichum sp. Present investigation revealed T. harzianum inhibited maximum 73.7 and 68% radial growth of Fusarium sp. and on Colletotrichum sp. Trichoderma hamatum inhibited maximum 71.6 and 73.8% radial growth of Colletotrichum sp. and Pythium sp., respectively.
