Abstract:
Plant growth promoting endophyticbacteria were isolated from maize (Zea mays L.) from different maize growing regions of Kalyana Karnataka. Totally 92 endophytic bacterial isolates were isolated from different parts of maize. Further based on the PGP traits exhibited by the endophytes, six efficient were selected and identified. The isolates were screened for antagonistic activity against Rhizoctonia solani and Fusarium moniliforme, causing banded leaf and sheath blight and stalk root and ear rot diseases in maize following dual culture method. Among the six efficient endophytic isolates, EKSB-8 showed highest inhibition of 42.00% against Rhizoctonia solani and EPSB-6 produced highest inhibition of 43.33% against Fusarium moniliforme respectively. The study confirmed the potential of plant growth promoting endophytes EKSB-8 (Pantoea dispersa) and EPSB-6 (Pseudomonas libanensis) as bio control agents against R. solani and Fusarium moniliforme pathogens of maize].
