The endophytes, Trichoderma harzianum-LF30, T. asperellum-SF33, Bacillus vallismortis-SB3 and green nanoparticle, Pseudomonas fluorescens-based zinc nanoparticles (Pf-ZnNPs) were first tested for their plant growth promotion activity with biocontrol agents T. viride (Multiplex Nisarga) and B. amyloliquifaciens in sorghum seeds. These endophytes and nanoparticles were tested for compatibility with each other and with chemical fungicides, mancozeb @ 0.2 percent, tebuconazole, propiconazole @ 0.1 percent, carbendazim 12% + mancozeb 63% and captan 70% + hexaconazole 5% @0.2%. Among endophytes and Pf-ZnNPs higher seed germination per cent was recorded in Pf-ZnNPs and seedling vigour was recorded in B. vallismortis -SB3.Based on compatibility test, consortia of T. viride-Multiplex Nisarga + T. harzianum-LF30 + T. asperellum- SF33 and B. vallismortis- SB3 + B. amyloliquifaciens were developed and included in management of pomegranate wilt study (pot culture). Among twelve treatments, these consortia and tebuconazole, propiconazole at 0.1% showed cent per cent disease reduction after 90 days of inoculation.
