Research Accomplishments: 
  • Developed spectral signatures and spectral indices for rice brown plant hopper with remote sensing techniques.
  • Assessed impact of effect of elevated CO2 on rice BPH in open top chambers (OTCs).
  • Developed pest-weather based forewarning thumb rule for rice BPH and Yellow stem borer for Mandya region, Karnataka, India.
  • Documented the wild pollinators in broccoli and studied the importance of wild pollinators in broccoli pollination and seed setting.
