Nanomaterials and their use can be powerful tools for managing plant resistance and disease control and could play a remarkable role in the agrotechnological revolution. Addressing food supply issues using modern methods also requires increased efficiency and in-depth understanding of their impact on the environment and humans. Furthermore, it is also critical for producers to ensure the sustainable use of such technologies and understand their mechanism of action, cost-effectiveness, and ease of use. The concerned study aimed to examine the modern approaches for improving the use of nanoparticles in plant disease management and control. Several methods for producing and analyzing nanoparticles, as well as their application in plant pathology, were in focus. The results associated with the synthesis of silver, copper, and zinc oxide nanoparticles were notable, with their morphology, structure, and biological activity also studied. Nanoparticles (<40 nm) appeared to exhibit the highest fungicidal activity against Fusarium oxysporum, Alternaria solani, Phytophthora infestans, and Helminthosporium turcicum. The study described mechanisms of nanoparticles’ antimicrobial activities, proposing improved approaches for their beneficial use in plant protection.

Metals and metal-oxide nanoparticles (AgNPs, CuNPs, ZnONPs, and FeNPs) (<40 nm) exhibited robust antifungal activity against primary phytopathogens through membrane damage and reactive oxygen species (ROS) generation. The integration of AgNPs + ZnONPs revealed the highest efficacy, providing 90%–95% pathogen suppression with enhanced seed germination.
