A field experiment was conducted to evaluate the efficiency of rhizosphere isolates as consortia to control wilt disease. Three rhizosphere isolates (RGB8, RGP7 and RGT4) were selected as efficient biocontrol agents based on their antagonistic activity against the pathogen and used for the development of microbial consortia. The results revealed that treatments inoculated with all the three isolates along with recommended dose of fertilizers (T8: RGB8+ RGP7+ RGT4+ RDF), showed significantly higher disease suppression and higher seed yield compared to all other treatments.
