Abstract:

Four antagonistic microorganisms Trichoderma viride, Metarhizium anisopliae, Pseudomonas fluorescens and Bacillus thuringiensis and their consortia were used to suppress Colletotrichum musae (Berk and Curtis), the causal agent of anthracnose disease of micropropagated banana during 2014-16. The compatibility tests conducted in vitro among these bioagents showed that all the bioagents were compatible amongst themselves. The consortia of different antagonists were tested to assay their ability to inhibit the growth of C. musae in vitro. The inhibition produced by the consortia of four bioagents T. viride, P. fluorescens, M. anisopliae and B. thuringiensis was significantly highest against C. musae (80.56%). The efficacy of the microbe based consortial formulations was also tested for their ability to suppress diseases caused by C. musae in vivo in pot grown micropopagated banana plantlets. There was a significant reduction of anthracnose disease incidence accompanied by enhancement of yield attributing characters in banana due to the application of consortial formulation of bioagents applied as root treatment and soil treatment.
