Division of Crop Protection

Primary tabs


The Division of Crop Protection had come into existence in 2020 after merging the erstwhile Divisions of Entomology & Nematology and Plant Pathology based on QRT recommendation.  The division is mandated with the following activities.

  • To conduct research to develop safe and sustainable technologies for integrated pest (insects, mites, nematodes, plant pathogens) management in horticultural ecosystems (Fruits, Vegetables, Ornamentals). 
  • To standardize technologies for production, value addition and popularization of mushrooms. 
  • Pollinator management to enhance crop productivity and conserve ecosystem services 
  • Training and farmers consultancy
  • Post Graduate Education


  • Phytosanitary services – testing export plants/planting  material
  • Post Entry Quarantine Inspection
  • Electron microscopy (SEM and TEM) facility for students and researchers 

Major areas of Research

  • Pest surveillance
  • Host Plant resistance
  • Disease diagnostics 
  • Post harvest pest and disease management
  • Virus vector interactions
  • Bio-pesticides and bio control agents for IPM and IDM
  • Pest management under protected cultivation
  • Exploring lesser known botanical pesticides
  • Semiochemicals for pest management
  • Impact of climate change on pests, diseases and pollinators
  • Application of drone technology in plant protection
  • Sterile insect Technique for area-wide pest management
  • Energy efficient technologies for spawn production and value addition of edible mushrooms
