Antagonistic potentiality of Trichoderma viride, T. harzianum and Pseudomonas fluorescens were evaluated against Fusarium oxysporum f. sp. ciceri under in vivo conditions. The effect of organic amendments viz; farm yard manure, vermicompost and mustard cake on disease control potentiality of test antagonists against chickpea wilt and on population dynamics of the antagonists and pathogen in soil was also studied. Maximum inhibition of mycelial growth of F. o. f. sp. ciceri was recorded in presence of P. fluorescens (%) followed by T. harzianum (%) and T. viride (%). Seed treatment with P. fluorescens was more effective in suppressing the disease incidence as compared to T. harzianum and T. viride. The disease control efficacy and population dynamics of all the three test antagonists was enhanced in response to application of organic amendments. Among the three organic amendments tested, mustard cake was most effective in enhancing the disease control potentiality of these antagonists.
