Agricultural and environmental applications of cold plasma

Research Directions:

  • Mycotoxin reduction and inactivation of seed-borne pathogens 
  • Seed germination improvement
  • Plasma activated water and micro/ultrafine bubbles as a green fertilizer and sanitizer for greenhouse and indoor farming - hydroponics and aquaponics 
  • Environmental applications of cold plasma
