Abstract
Groundnut or peanut (Arachis hypogaea L.) is one of the important economic oilseed crops of the world. Among various soil borne pathogens, Sclerotium rolfsii causing southern blight is of most important, causing huge losses in groundnut. The Sclerotium rolfsii culture was obtained from Department of Biotechnology, University of Agricultural Sciences, Dharwad. The identification and confirmation of the isolate was done by cultural characteristics, pathogenicity test. In in vitro studies plant growth promoting rhizobacteria viz., actinobacteria and pseudomonas spp. were used. Initially, 257 actinobacteria and 134 Pseudomonas isolates were screened against S. rolfsii. Out of these isolates, nine isolates showed significant inhibition of pathogen and these isolates were further selected for in vivo evaluation under greenhouse conditions S. rolfsii. Percent disease incidence and percent disease control were recorded. Under challenge inoculation with S. rolfsii, the Pseudomonas isolate, AUDP 48 showed significant control of the southern blight disease compared to other rhizobacteria. Growth parameters such as shoot length, root length and total fresh and dry weight are also observed far superior in this treatment.
