  • Studies on management of viral diseases
  • Adaptive trials for other spices such as Black pepper


  • Development of Integrated Pest Management (IPM) strategies for cardamom, Bioecology, Bionomics,behavioural and physiological approach in pest management
  • EvolvingBio-control measures, bio-pesticide formulation and screening natural enemies against pests of cardamom for developing organic farming practices.
  • Studies on minor pests in cardamom
  • Pestsurveillance and forecast for possible pest outbreaks


  • Post-harvest handling, processing techniques like cardamom curing, vanilla processing, herbal spices drying etc.
  • Packing and storage of spices
  • On-farm value addition techniques for white pepper production, vanilla curing etc.


This division aims at bridging the gap between scientists and planters by transferring the achievements in the institute for application in the planters’ field. This is mainly achieved through training programmes, conducting seminars, group discussions, exhibitions, organising spice clinics etc. Scientists of the institute serve as the resource personnel in seminars and planters meetings

  • Training programmes on production, protection and post-harvest technologies& management of cardamom, vanilla and other important spices for farmers and entrepreneurs.
  • Two months residential training programme on Good Agricultural Practices (GAP) for quality spice production for unemployed youth.
  • Hands-on training programme on Bio-agent production (Trichoderma,Pseudomonas, EPN) for farmer groups and NGOs.
  • Training to extension functionaries from the Development Department of Spices Board, State Agricultural Department etc on latest technology/ developments.
  • Mobile spice clinics and farmer scientist interface programmes in different cardamom growing locations to address field level problems.

  • Hybridization in large cardamom for evolving high yielders.
  • Breeding for tolerance to frost as well as major diseases and pests.
  • Development of agro-techniques like nutrient requirements, population density, cultural practices etc. to render optimum yield.
  • Studies on Biology, Bionomics of major insect pests and evolving control measures for major insect pests.
  • Studies on important fungal and viral diseases of large cardamom
  • Epidemiology &control of viral diseases ‘Foorkey’ & ‘Chirke’ as well as clump rot.
