Bio prospective management approach for the pathogens associated with micropropagated banana plantlets
Author(s): J Dutta, LC Bora, A Tamuly and R Deb
Abstract: During 2014-16, four antagonistic micro-organisms such as Trichoderma viride, Metarhizium anisopliae, Pseudomonas fluorescens and Bacillus thuringiensis and their consortial formulations were used to suppress Ralstonia solanacearum, the causal agent of bacterial wilt disease of micropropagated banana. In vitro tests were conducted to evaluate compatibility and the antagonistic ability of all the bioagents and their combinations against wilt pathogen, R. solanacearum. Combination of B. thuringiensis, T. viride, M. anisopliae and P. fluorescens showed significantly highest inhibition (97.06%). The efficacy of the microbe based consortial formulations was also tested for their ability to suppress diseases caused by R. solanacearum in vivo in pot grown micropropagated banana plantlets. There was a significant reduction of bacterial wilt disease incidence accompanied by enhancement of yield attributing characters in banana due to application consortial formulation of bioagents applied as root treatment and soil treatment.
