ABSTRACT
Efficacy of soil amendment with Lantana camara and various concentrations of three phenolics (caffeic acid, p-hydroxybenzoic acid and (p-coumaric acid) were tested against the soil-borne root-infecting fungi (Fusarium solani and Rhizoctonia solani) in unsterilized sandy-loam soil. The potential impact of L. camara amendment on the rhizosphere population of Pseudomonas aeruginosa and consequent biocontrol potential was also evaluated. Powdered L. camara and its aqueous extract caused substantial suppression of F. solani and R. solani infection in mungbean roots. At high concentration of L. camara (1% w/w), population of P. aeruginosa in the rhizosphere declined but not to a degree that could reduce biological control and growth promoting potential of the bacterium. L. camara and P. aeruginosa used together caused greater suppression of the root-infecting fungi as compared to their individual application. P. aeruginosa mixed with L. camara also resulted in enhanced plant growth. Soil application of caffeic acid at the rate of 10-μg/g soil caused complete inhibition in germination of mungbean. With an increase in phenol concentration, plant growth was progressively reduced and root infection caused by F. solani and R. solani was suppressed. Caffeic acid at 5-μg/g soil caused greater suppression of F. solani whereas p -hydroxybenzoic acid at 10 μ g/g resulted in the maximum inhibition of R. solani.
