Nanotechnology: A double-edged sword for future smart agriculture and phytopathological management in plants

Modern technology that would boost agricultural outputs might therefore preserve the country's sustainable living standards by enhancing food security. With nanotechnology, it’s possible to produce foods of exceptional quality that also could increase the bioavailability of nutrients during the third decade of the twenty-first century which found usage in a variety of industries such as medical science, pharmaceuticals, food, and energy conservation. Nanotechnology is the synthesis, designing, characterizing, and utilization of assemblies, tools, and systems via directing the morphology and size variation at nanometer level (1 - 100 nm). Nanochemicals, nanopesticides, and nanofertilizers do increase yielding capacity without damaging agricultural land or irrigation water. Nanomaterials (NMs) are aimed protect crops from pests, microbial and fungal pathogens thereby lowering nutrient losses. Nanotechnology holds the potential to monitor soil quality in agricultural fields and sense crop health. Metallic Nanoparticles (Cu, Zn, Ni, Zn Fe, Ag, Al, Ti, and Al) can impinge on plant development, metabolism, and stress tolerance. This paper examines the role that nanoparticles (NPs) be playing while regulating oxidative stress, ROS turnover to mitigate abiotic stress in plants thereby emphasizing the advantages and of nanotechnology for better sustenance of future agriculture practices.
