Abstract :
[en] This study evaluated the antifungal e ects of various volatile organic compounds (VOCs) against twocommonpathogens: Fusarium culmorum and Cochliobolus sativus. Amongthe various VOCs, methyl propanoate (MP) and methyl prop-2-enoate (MA) exhibited remarkable antifungal e ects under di erent experimental conditions (direct or indirect contact) and at di erent concentrations (500–1000 M). In addition, the type of antifungal e ect (fungistatic or fungicidal) appeared to be strongly correlated with the VOC concentrations. Additional tests revealed that both molecules increased membrane permeability of pathogenic spores, which resulted in a decreased e ux of K+ ions into the intracellular medium.
