Efficacy of some fungal and bacterial bioagents against Fusarium oxysporum f.sp. ciceri on chickpea

The efficacy of four fungal bioagents viz., Trichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens and two bacterial bioagents namely Pseudomonas fluorescens and Bacillus subtilis were evaluated against the chickpea vascular wilt pathogen, Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. Among the fungal bioagents, T. harzianum produced the maximum inhibition zone of 17 mm compared to the minimum of 7 mm by T. hamatum. There was no significant difference between the inhibition zones produced by P. fluorescens and B. subtilis. Soil application of talc- based formulation of T. harzianum, P. fluorescens and G. virens effectively controlled the vascular wilt of chickpea under field condition.
