Using a PGPR isolated from the field of same plants, we aimed to study effect on control of this disease as well as to study effect on seed germination and development of Induced systemic resistance in germinated seedlings. Methods: Different strain of bacteria were isolated and screened for their plant growth promoting activity. Selected bacterium was used for induction of systemic resistance in A. hypogaea L. against A. niger and identified using 16s rRNA gene and FAME analysis. Results: A bacterium with plant growth promoting and antagonistic activity against A. niger was screened from the 25 bacteria isolated from the rhizospheric soil. It could reduce the incidence of collar rot disease by 66% in plants. The bacterium could also induce systemic resistance in ground nut seedlings. Based on ez taxon BLAST results of its 16s rRNA gene, biochemical tests for identification and FAME analysis, it was confirmed as a novel strain of Pseudomonas guariconensis (strain mungfali). Conclusion: A novel, agriculturally useful strain of P. guariconensis capable of controlling collar rot in A. hypogaea L., producing phytohormones and solubilizing N, P, K and Zn was found and named as strain mungfali.
