Exserohilum turcicum is a fungal phytopathogen causing turcicum leaf blight and responsible for a severe loss of yield in maize. This work was aimed to characterize the rhizospherie fluorescent Pseudomonas having antagonistic property against E.turcicum, characterized by biochemical tests and 16S r DNA sequences. Out of total 33 isolates, 6 bacterial strains viz., MBLK1, MBLK3, MBLK6, MBLK15, MBLK17, and MBLK22 were found to be antagonistic against E.turcicum. Antagonistic bacteria were analyzed for their plant growth promotion ability on maize variety HUZ-M60.

Exserohilum turcicum is a fungal phytopathogen causing turcicum leaf blight and responsible for a severe loss of yield in maize. This work was aimed to characterize the rhizospherie fluorescent Pseudomonas having antagonistic property against E.turcicum, characterized by biochemical tests and 16S r DNA sequences. Out of total 33 isolates, 6 bacterial strains viz., MBLK1, MBLK3, MBLK6, MBLK15, MBLK17, and MBLK22 were found to be antagonistic against E.turcicum. Antagonistic bacteria were analyzed for their plant growth promotion ability on maize variety HUZ-M60.
