Cucumis sativus (Cucumber) is very valuable crop plant in India. Direct application of Trichoderma sp .has proved effective in controlling the infection by Fusarium (soil borne pathogen) one of cucumber plants under greenhouse conditions. A wilt caused by Fusarium oxysporum f.sp. Cucumerinum is a majer problem in the production of Cucumis sativus (Cucumber) plants. In dual culture a significant reduction was observed. Positive correlation between added Trichoderma and percentage of healthy cucumber seedlings were detected. Improved seedling vigour was noticed in fungal antagonist filtrate treated seeds evidenced by maximum shoot length (19.5 cm respectively) followed by fungal antagonist suspension treated pot (20 cm) while untreated seeds in inoculated control (respectively). Percent seedling mortality was recovered in untreated seeds in uninoculated soil was 40%, in coated seeds in inoculated soil was 6.25%, in filtrate treated seeds in inoculated soil was 12.5% and untreated seeds in inoculated soil was 87%.Percent disease control was calculated to be 86.99% for antagonist filtrate treated seeds in infected soil and 93.62% for antagonist coated seeds in infected soil over untreated seeds in Fusarium infested soil taken as check so the strongly suggest that Trichoderma sp can ve exploited for the biological control of soil borne pathogens ( Fusarium oxysporum f.sp. Cucumerinum.).
