Assessment on potential of bacterial biocontrol agents on plant parasitic nematodes in banana

Abstract

Field experiments on management of nematodes in banana was conducted to assess the efficacy of plant growth promoting rhizobacteria, single and combined application of Pseudomonas fluorescens and Bacillus subtilis. All the treatments were significantly increased the yield parameters viz., stem girth, plant height and number of leaves per plant and observed that the reduction of nematode population in root system. Eighty-six per cent of nematode population was reduced from the initial nematode population recorded in combined application of P. fluorescens (Pfbv 22) + B. subtilis (Bbv57) each 12.5 g/plant respectively compared to untreated control followed by single soil application of P. fluorescens (Pf1) @ 25/ plant recorded lowest nematode population compared to untreated control.
