Emerging pesticide-resistant phytopathogenic bacteria have become a stumbling block in the development and use of pesticides. Quorum sensing (QS) blockers, which interfere with bacterial virulence gene expression, are compelling way to manage plant disease without resistance. Herein, series isopropanolamine-decorated coumarin derivatives were designed synthesized, their potency interfering QS was investigated. Notably, compound A5 exhibited better bioactivity median effective concentration (EC50) values 6.75 mg L-1 against Xanthomonas oryzae pv. (Xoo) than bismerthiazol (EC50 = 21.9 L-1). Further biochemical studies revealed that disturbed biofilm formation suppressed factors so forth. Moreover, decreased expression QS-related genes. Interestingly, had acceptable control effect (53.2%) toward Xooin vivo. Overall, this study identifies novel lead for bactericide candidates diseases by QS.

Plant pathogens pose a significant threat to agricultural productivity and food security worldwide. The use of traditional chemical pesticides for plant disease management raises concerns due the emergence pesticide resistance their potential adverse effects on human health environment. As result, there is growing interest in exploring alternative approaches control. This review provides an overview antimicrobial some plant-derived compounds, including essential oils, extracts, wastes major constituents, against pathogenic bacteria. activity attributed diverse composition these compounds ability target multiple cellular processes pathogens’ cells. Furthermore, explores antagonistic bacteria fungi as control tools. These beneficial microorganisms have shown promising results suppressing growth through various mechanisms such competition, antibiosis induced systemic resistance. discusses advantages limitations using management. Moreover, it highlights need further research optimize efficacy, develop sustainable formulations evaluate performance under field conditions.
