Plant pathogens, including bacteria, fungi, and nematodes, continually pose a threat to economically significant crops, causing considerable yield losses. Despite the availability and utilization of diverse chemical treatments, the issue of yield loss still requires attention. Nanotechnology, which exploits the potential of various nanoparticles, offers a dynamic and advanced gateway to plant disease control. Gold, silica, silver, chitosan, cerium, titanium dioxide, alumina-silicate, zinc, gold-silver alloy, and silica-silver are among the nanoparticles employed to combat plant pathogens. These nanoparticles possess antibacterial and antifungal properties, enabling them to modify bacterial cells and impede fungal mycelial growth, making them excellent candidates for deployment against plant pathogens. Moreover, bacteria, fungi, and plants are among the biological sources actively involved in synthesizing nanoparticles. Nanoparticles can also serve as highly effective nanosensors and biomarkers, facilitating faster and more accurate detection of plant diseases. This review paper primarily focuses on nanoparticles' utilization in managing various phytopathogens.
