Management of Plant Diseases with Green Synthesized Nanoparticles Using Plant Extracts

Nanotechnology is a rapidly advancing field that has effectively tackled various issues across multiple industries, including agriculture. Nanoparticles (NPs) can typically be synthesized using two different techniques: top-down approach and bottom-up approach. In top-down approach, NPs are generated by reducing the size of a larger material, resulting in agglomerates with nano sized particles. Bottom-up approach involves building nanoscale structures from atomic and molecular components. In agriculture, nanotechnology plays a role in the production of nanoscale fertilizers, pesticides, and herbicides. Nanoparticles are used in plant disease management as well. The green synthesis of nanoparticles is often referred to as biosynthesis. It uses a range of biological sources like microorganisms or their derivatives as well as plant extracts, instead of synthetic chemicals, with minimal impact on human health and the environment. Green-synthesized nanoparticles (GSNPs) are known for their ease of production and cost-effectiveness. They offer several advantages, including their ability to induce systemic resistance to diseases and exhibit fungicidal and bactericidal properties.
