Rhizobacteria are used as inoculants to enhance crop yield
and for biological control of fungal pathogens. Fluorescent
pseudomonads isolated from the rhizosphere of groundnut
showed suppression of the phytopathogen Macrophomina
phaseolina that causes charcoal rot of groundnut, an
economically important agroproduct. Two strains of
fluorescent pseudomonads, designated as PS1 and PS2,
were selected as a result of in vitro antifungal activity.
After 5 days of incubation at 28±1oC, both PS1 and PS2
caused clear inhibition zones in dual cultures, restricting
the growth of M. phaseolina by 71% and 74%, respectively.
Both the strains were capable of producing siderophores,
indole acetic acid, and hydrocyanic acid, and causing
phosphate solubilization under normal growth conditions.
These strains, when used as inoculants in groundnut, enhanced
germination up to 15% and 30% with subsequent increase
in grain yield by 66% and 77%, respectively. Conversely,
when the pathogen alone was tested 57% decrease in
yield was recorded. Thus the studies revealed the potential
of the two pseudomonads not only as biocontrol agents
against M. phaseolina, but also as a good growth promoter
for groundnut.
