Abstract
Generally, advancements in various branches of science and technology have had a significant impact on various aspects ofplant pathology like efficient pathogen detection. Nanotechnology is found to have many applications of which plantpathology is the one important field. In recent years, nanotechnology has been increasingly applied to the development ofnovel antimicrobials for the management of pathogenic bacteria affecting agricultural crops. This review discusses theapplications of different nanoparticles in plant disease management and their mode of action against the bacteria. Thesynthesis of nanoparticles (NPs) using biomolecules (protein, enzyme, DNA and plant extracts) have opened a newavenue of research in green nanobiotechnology. They are proved to be effective, cheap and eco-friendly in combatingmicrobes. Reactive oxygen species production, lipid peroxidation, protein oxidation, ATP depletion and DNAdegradation are some of the mechanisms by which nanomaterials used to kill bacteria.
