Green Nanotechnology for Protecting Plants against Bacterial Diseases

Green nanotechnology offers a sustainable and innovative approach to managing bacterial diseases in agriculture. The unique physicochemical properties of green-synthesized nanoparticles have demonstrated potent antibacterial activity, disrupting bacterial membranes and generating Reactive Oxygen Species (ROS). These nanoparticles are synthesized through eco-friendly methods using biological materials, which reduces environmental harm and offers biocompatibility advantages over conventional nanoparticles. This chapter explores the potential of green-synthesized nanomaterials in bacterial disease control, highlighting their mechanisms of action, including interference with bacterial DNA replication and enzyme function. It also addresses current challenges, such as production costs, regulatory barriers, and the need for long-term environmental studies. Despite these challenges, green nanotechnology represents a promising alternative to conventional agrochemicals, potentially transforming plant disease management.
