There is a great problem of farmers to protect their food crops from pathogenic microbes. Some fungi play a major role to have an effect on the crop’s yield and survival. On visiting farmer’s field in bakshi ka talab lucknow, some diseased crop plant and their fruits have been found. After screening the diseased area of sampled crop plants causal fungi get isolated and identified morphologically in the laboratory. The isolated and purified pathogenic fungi are Chollatotrichum from red rot of sugarcane, Alternaria from brown-black discoloration of cauliflower, early blight of tomato and black round spot of apple, Paracercospora from leaf spot disease of banana and Fusarium from wilt root of pegion pea and black margine of curled potato leaf. Some species of Trichoderma like T. hargianum, T. viride, T. hamantum have a potential to inhibit the growth of pathogenic fungi. Trichoderma had shown significant antagonistic activity against isolated pathogenic fungi Chollatotrichum, Alternaria, Paracercospora and Fusarium species. From this result we have found the trichoderma as a potential biocontrol agent against pathogenic fungi.
