Synergistic antimicrobial effects of ferulic acid combined with near-ultraviolet and short-wave blue light and its application to suppressing Fusarium head blight disease

Key Points

• Investigate the antimicrobial effects of ferulic acid combined with near-ultraviolet and blue light on Fusarium head blight disease.
• Evaluated antimicrobial activity of ferulic acid with near-ultraviolet (365 nm) and short-wave blue light (385-405 nm) against fungi.
• Measured the concentration reduction of deoxynivalenol (DON).
• Assessed toxicity effects on HepG2 cells after treatment with the combination.
• Ferulic acid alone showed low antimicrobial activity, but combined with light it exhibited synergistic effects.
• Combined treatment significantly reduced DON levels.
• Treatment with ferulic acid and near-ultraviolet light effectively suppressed DON production by Gibberella zeae.
