Efficacy of Fungi Toxicants and Bio Control Agents against Fusarium oxysporum f. sp. ciceri

Bio control agents (Trichoderma viride, Pseudomonas fluorescens) and various fungitoxicants were tested for their efficacy in controlling the Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceri in vitro and in vivo. In vivo conditions soil inoculated with Fusarium oxysporum f. sp. ciceri was conducted to compare the efficacy of different treatments viz. seed treatment with bio-control agents and fungitoxicants in the management of chickpea wilt. All the treatment significantly reduced the wilt incidence. Bavistin, Thiram and Trichoderma viride were the most effective and reduced the wilt incidence as compared to inoculated control respectively whereas neem leaf and neem bark was the least effective over inoculated control. Seed treatment with Pseudomonas fluorescens and Trichoderma viride effectively enhancing the growth of chickpea viz. Shoot length, root length, shoot weight and root weight as compared to control. In vitro condition all the treatments used in vivo conditions were evaluated at different concentrations for their efficacy is significantly inhibited the radial growth of Fusarium oxysporum f. sp. ciceri. All the treatments were effective and significantly reduced the radial growth of Fusarium oxysporum f. sp. ciceri.
