Antifungal activity and the mechanism of dehydrocostus lactone from Saussurea costus roots

Key Points

• This research aims to evaluate the antifungal properties of dehydrocostus lactone from Saussurea costus roots and its mechanism of action against fungal pathogens.
• Isolation of dehydrocostus lactone from Saussurea costus roots
• Assessment of antifungal activity against M. oryzae
• Analysis of infection-related morphogenesis inhibition
• Dehydrocostus lactone effectively prevents rice blast disease in plants
• Inhibition of M. oryzae morphogenesis was observed
• Potential identified for dehydrocostus lactone as an alternative bioagent in controlling fungal diseases
