Fusarium oxysporium f. sp. cubense (Foc) race is an archetypally soil-born fungus causing chief fiscal damage to farmers growing banana plants. Supervising Foc is attained by the habit of chemical fungicides which undesirably harm the soil fertility. Our investigations intended to activate the aptitude of Trichoderma strains for activation of PGPR and IIR. The activation and accretion of defence enzymes such as Polyphenol Oxidase (PPO), Phenylalanine Ammonia-Lyase (PAL) and Peroxidase (PO) are been amplified by inoculation, and treatment with a combination of Trichoderma harzanium and Trichoderma viride strains (T3-H1+V1). Besides combination-based inoculum treatments gave best results than individual and fungicide-treated plantlets for supervising Foc pathogenesis. Based on the results we conclude that usage of T1-H1 and T2-H2 treatments with a combination such as T3-H1+V1 gave promising results and can be used as a prominent biocontrol formulation for inducing defence enzymes and PGPR in Musa paradisica cv. Malnad Rasbale.
