Abstract :Fungal plant pathogens represent a significant threat to global agriculture, affecting crop productivity and food security. Phytophthora infestans and Monilinia laxa are two such pathogens causing blights and brown rot, respectively, in economically vital crops like potato and stone fruits. Developing sustainable management strategies is crucial to mitigate these threats. Xenorhabdus and Photorhabdus bacteria produce various secondary metabolites with different biological activities. This study investigates the antifungal activity of cell-free supernatants from Xenorhabdus and Photorhabdus bacteria against P. infestans and M. laxa. Results demonstrate varying degrees of antifungal efficacy among bacterial species, with X. cabanillasii and X. szentirmaii exhibiting significant suppression of fungal growth. The findings underscore the importance of exploring biocontrol agents in integrated pest management practices.
