Abstract Among the various strains of Trichoderma viride, the tested strain MG 6 was found to be more effective in inhibiting the growth of Pythium aphanidermatum, the casual agent of rhizome rot in turmeric. Various substrates were tested for the in situ multiplication of selected strain (MG 6). Among them farmyard manure (FYM) was found to be most suitable. When the FYM-based biomanure was applied to turmeric plants it induced the activity of various plant defence enzymes such as peroxidase, polyphenol oxidase and phenyl alanine ammonia lyase. The induction of 6 and 4 isoforms of PO, 10 and 9 isoforms of PPO viz., in leaf and rhizome, were observed in plants applied with T. viride (MG 6). The early and increased expression of defence genes can induce systemic resistance in plants against pathogens.
