Fermented chrysanthemum stem as a source of natural phenolic compounds to alleviate tomato bacterial wilt disease.

ABSTRACT: Natural antimicrobial compounds (NACs) in the plant stem are crucial for replacing conventional synthetic pesticides in the control of soil-borne diseases, and microbial fermentation can enhance their concentration and bioactivity. In this study, the stems of 10 plant species were collected for fermentation by probiotic bacteria Bacillus amyloliquefaciens T-5 to identify the most effective plant resource for controlling tomato bacterial wilt disease and discover key NACs. Chrysanthemum stem was identified as an optimal fermentation substrate, as its water-soluble extracts (WSEs) significantly inhibited the growth of pathogenic Ralstonia solanacearum and effectively alleviated tomato wilt under greenhouse conditions. Key metabolites, primarily phenolic acids including 2-hydrox
