This study was intended to evaluate the biocontrol efficacy of rhizobacteria isolated from turmeric fields against fungal pathogens, which are associated with the rhizome rot of turmeric. The antagonistic potential of 157 rhizobacterial isolates obtained from the turmeric fields was assessed against seven rhizome rot fungal pathogens; namely, Rhizoctonia solani MML4001, Fusarium solani MML4002, Schizophyllum commune MML4003, Macrophomina phaseolina MML4004, Fusarium graminearum MML4005, Fusarium solani MML4006 and Fusarium solani MML4007. Sixteen rhizobacterial isolates exhibited consistent antagonistic activity against all seven tested rhizome rot fungal pathogens. Experiments were done to assess various biocontrol mechanisms and plant growth promoting traits exhibited by these 16 selected rhizobacterial isolates. Polyphasic taxonomical identification revealed them as Pseudomonas aeruginosa MML2424, P. aeruginosa MML2515, P. aeruginosa MML2519, Bacillus amyloliquefaciens MML2522, B. amyloliquefaciens MML2547, Bacillus tequilensis MML2476, Bacillus cereus MML2533, Bacillus subtilis MML2406, B. subtilis MML2411, B. subtilis MML2415, B. subtilis MML2451, B. subtilis MML2458, B. subtilis MML2473, B. subtilis MML2483, B. subtilis MML2490 and B. subtilis MML2518 (GenBank Accession numbers: KJ655538 to KJ655553). Detection of genes encoding for different biocontrol traits viz., production of antibiotics; i.e., 2,4-diacetylphloroglucinol, pyrrolnitrin, pyoluteorin, bacillomycin D, fengycin, hydrogen cyanide, and lytic enzyme, cellulase in these strains was carried out by polymerase chain reaction using gene-specific primers. Furthermore, field experiments were conducted using bioformulations of eight selected promising biocontrol-PGPR. Results of this study revealed that most of the PGPR, particularly P. aeruginosa MML2424 and B. subtilis MML2490, appeared promising for commercialization, which can be used for plant growth promotion and management of turmeric rhizome rot disease.
