Soil borne plant pathogens cause potential yield loss in every year all over the world. Antifungal Trichoderma isolates can control soil borne plant pathogenic fungi. Soil samples were collected from different agricultural fields to find out effective Trichoderma isolates. Their antifungal and morphological characteristics were studied. Radial mycelial growths of the isolates varied from 29.91 to 90.00 mm in vitro assay. On the basis of shape, growth habit, colony color, compactness, spore density isolates were categorized in different groups. Different selected temperature such as: 20o, 25 o, 30o and 35o C were maintained in incubators to observe the growth habit of different Trichoderma isolates. Optimum growth of Trichoderma isolates was recorded 25 to 30
