Advisors: Dr M V Deshpande

• Objectives:

  • Isolation of novel microbial strains from NE region to develop bioinputs to support organic agriculture

  • Identification of novel genes, generation of multi-locus DNA barcode sequences of new and important microbial strains​

  • Bioprospecting novel microbial strains for bioremediation​

  • Exploring plant wealth for disease and pest management

• Salient Achievements:

  • Eleven biopesticides have been developed

  • Protocol has been developed for mass multiplication of Biogreen L and Biogreen 5

  • Technology commercialized: Trichoderma viride based Biopesticide ‘Bioveer’ registered with CIB [Reg. No. CIR-1729/2015(355)-Trichoderma viride (WP)-391]

  • Registration of BioFor-PF-2 is in the pipeline

• Efficacy of different microbe-based bioformulations on:​

  • Citrus canker disease (AAU, Jorhat): Biogreen (Soil+Foliar) is most effective with 20.84% of disease incidence as compared to 72.99% in control; 41.93% increase in fruit yield from no yield in control

  • Bacterial Blight Disease of Rice (AAU, Jorhat): Biogreen @ 2% is most effective in reducing disease severity from 90.31% in control to 29.43% after application

  • Kharif rice (RARS Titabar): Biotime (4 sprays) reveals highest efficacy in reducing Stem borer damage from 15.8% (Dead heart) and 16.4% (White ear head) to 3.2% and 4.1% respectively

  Expected outputs:

  • Large-scale production of biopesticides for commercial release

  • Novel microbe-based bioformulations

  • CIB registration and IPR protection of biopesticides of barcoded microbial strains

  • Technology for disease suppression vis-a-vis pesticide bioremediation with a single formulation
