Mycoparasitic Pseudomonas spp. against infection of Fusarium chlamydosporum pathogen in soyabean (Glycine max) plant

Fusarium species are generally appropriated pathogens in roots, plant debris and soil causing major disease as primary, secondary invader and co-invader with other pathogens. Fusarium chlamydosporum is the second most important pathogen, followed by F. solani to cause root rot disease in soybean (Gl...

Summary:Fusarium species are generally appropriated pathogens in roots, plant debris and soil causing major disease as primary, secondary invader and co-invader with other pathogens. Fusarium chlamydosporum is the second most important pathogen, followed by F. solani to cause root rot disease in soybean (Glycine max) crop. The present study explores mycoparasitic activity of Pseudomonas aeruginosa (OG101) and Pseudomonas putida (PP) for the management of Fusarium infection in soybean crop. Investigation of glucanase production, chitinase production as well as effect on spore germination was assessed for in vitro biocontrol activity of Pseudomonas sp. and obtained that P. aeruginosa (OG101) produced 13% higher glucanase, 12% higher chitinase and 15% more spore inhibition as compared to P. putida (PP). Disease index of 1.73 and 2 was observed in plants treated with P. aeruginosa (OG101) and P. putida (PP) in presence of pathogen F. chlamydosporum, respectively. Both strains exhibited mycoparasitic activity which helps in management of fusarial infection in Glycine max.
