In this study, we aim to realize sustainable agriculture with reduced dependence on chemical pesticides and fertilizers by selectively synthesizing and supplying highly reactive species using atmospheric-pressure air plasma and applying them to plants. High-density N₂O₅ and NO₃ radicals were selectively synthesized from dry air via reactions between O₃ and NO/NO₂. Spraying these plasma-synthesized species onto plants was shown to enhance plant immunity, increase the production of secondary metabolites, and promote seed germination.
