Cucumber Fusarium wilt caused by Fusarium oxysporum f. sp. cucumerinum is one of the most serious fungal diseases in cucumber production in the world. In this study, six bio-agents viz., Trichoderma harzianum, Trichoderma viride, Trichoderma asperellum, Pseudomonas fluorescens, Bacillus subtilis and Aspergillus niger were evaluated for their ability to inhibit the pathogen growth under in vitro and in vivo conditions. The pathogen which causes Fusarium wilt of cucumber, was isolated and identified as Fusarium oxysporum f. sp. cucumerinum (FOC). All the bioagents were obtained from Department of Plant Pathology, S.K.N. College of Agriculture, Jobner, Jaipur. The results of this study revealed that Trichoderma harzianum was found most effective in inhibiting the radial mycelial growth of the pathogen (85.90%) followed by Trichoderma viride (82.50%) Trichoderma asperellum (79.63%), Bacillus subtilis (68.52%) Pseudomonas fluorescens (64.81%) and Aspergillus niger (51.85%) compared to control under in vitro conditions by Dual Culture Method. Whereas under cage house condition Trichoderma harzianum was found most effective in reducing incidence of Fusarium wilt of cucumber.
