 ABSTRACT

A total of seven rhizobacterial isolates (AUDT 240, AUDT 248, AUDT 502, AUDT 801, AUDT 807, AUDT 811and AUDP 139) and one reference isolate of Trichoderma harzianum were examined for antagonistic activities against five different isolates of Macrophomina phaseolina viz., Belavadi, Dharwad, Kalaburagi, Savanur and Vijayapura. The isolate AUDP 139 (Pseudomonas fluorescens) showed maximum mean per cent inhibition (56.50 %) followed by AUDT 240 (47.24 %) and AUDT 801(46.33 %). Results indicated that the isolates AUDP 139, AUDT 240 and AUDT 801 could be a novel  biocontrol agents for the management of charcoal rot of sorghum.

Keywords: Sorghum, Charcoal rot, Rhizobacteria.
