The management of bacterial wilt disease in tomato plants poses a significant challenge to global agriculture. Nanoparticles have emerged as promising tools for disease control due to their unique physicochemical properties. This study investigates the impact of nanoparticle exposure on tomato bacterial wilt disease through modulation of the rhizosphere bacterial community. Tomato plants were treated with Silver Nanoparticles (AgNPs), Copper Nanoparticles (CuNPs) and Zinc Oxide Nanoparticles (ZnONPs) and their effects on disease suppression and rhizosphere bacterial composition were assessed. Next-generation sequencing of bacterial DNA revealed significant alterations in the rhizosphere microbiome following nanoparticle exposure. Furthermore, nanoparticle-treated plants exhibited varying degrees of disease suppression compared to control plants. Our findings highlight the potential of nanoparticle-mediated modulation of rhizosphere bacterial communities as a novel strategy for enhancing plant health and combating bacterial wilt disease in tomatoes.
