Chitosan vs. chitosan nanoparticles in the control of Fusarium graminearum: A synergistic effect of fungitoxic activity and plant defence activation?

Description

Abstract: Chitosan and chitosan nanoparticles are able to inhibit the germination and mycelium growth of Fusarium graminearum and to control wheat head blight caused by this dangerous fungus. When loaded with the antioxidant N-acetyl cysteine chitosan nanoparticles lose their activity. in planta, suggesting that the control of head blight by nanoparticles is mediated by an oxidative burst.
