COMBINATION OF FUNGAL AND BACTERIAL ANTAGONISTS FOR MANAGEMENT OF ROOT AND STEM ROT DISEASE OF SOYBEAN
D.S. MISHRA1, A.K. GUPTA2,
C.R. PRAJAPATI3 AND U.S. SINGH4
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.
