Abstract
Trichoderma harzianum and plant growth promotory rhizobacteria Pseudomonas fluorescens were tested alone and in combinations for their relative biocontrol potential against many soil-borne plant pathogens viz., Rhizoctonia solani, Sclerotium rolfsii and Macrophomina phaseolina responsible for root and stem rot disease of soybean. Investigations under glass-house and field conditions revealed a general trend towards greater suppression and enhanced consistency against the pathogens by mixture of antagonists. Application of more than one antagonists of diverse origin is suggested as a reliable means of reducing the variability and increasing the reliability of biological control.
