Salient Achievements:
  • Facilitated in safe exchange of germplasm under Quarantine:import / export crop germplasm in South India and post-entry quarantine inspections on import crop germplasm meant for private industry, public organizations and international institutes
  • Identified promising isolates of fluorescent pseudomonads, viz., Pseudomonas putidaDAPG1 (GenBank: JX514425) and P. putida DAPG3 (GenBank: JX14404) for management of root-knot nematode, Meloidogyne arenaria in groundnut.
  • Documented the plant parasitic nematodes affecting major flower crops.
  • Standardised the bio-formulations for management of root-knot nematode, M. incognita in tuberose
  • Young Scientist Award-2018” by Society of Plant Protection Sciences, New Delhi on 20th December, 2018 for significant contribution in the field of Nematology. 
  • Treasurer, Plant Protection Association of India, ICAR-NBPGR, Rajendranagar, Hyderabad, India (2018-20).
  • Best Poster Awardat National Conference on Floriculture for urban prosperity in the scenario of climate change held at CAE&PHT (CAU), Ranipool, Sikkim from 16-18th February, 2018
  • Councillor of West Zone, Nematological Society of India (Division of Nematology), IARI, New Delhi (2015-17).
