Biological control of tomato bacterial wilt and apple fire blight through the induced resistance of azomycin derived from <i>Streptomyces</i> sp. JCK-8368.

ABSTRACT: Tomato bacterial wilt and apple fire blight, caused by Ralstonia solanacearum and Erwinia amylovora, respectively, are highly destructive diseases that threaten global agriculture productivity. Increasing resistance of these pathogens to conventional antibiotics and copper-based pesticides highlights the urgent need for sustainable, eco-friendly biocontrol alternatives. This study aimed to evaluate the biocontrol potential of the azomycin-producing Streptomyces sp. JCK-8368 (hereafter JCK-8368) against tomato bacterial wilt and apple fire blight, and to investigate its possible resistance-inducing mechanism. The culture filtrate (CF) of JCK-8368, containing azomycin, was applied to the plant at 1,000-fold (100 ng/mL), 500-fold (200 ng/mL), and 250-fold (400 ng/mL) dilu
