Nanotechnology has revolutionized agriculture with the development of nanoparticles with unique properties. Ranging from 1-100 nanometers, these NPs exhibit distinct physicochemical characteristics, such as high surface area and tunable reactivity. Among these, CuO NPs stand out as ideal candidates for various agricultural applications, including their use as pesticides, herbicides, and targeted nutrient delivery systems . However, there are toxicological and environmental issues with using chemically generated CuO NPs. To address this issue, sustainable approaches have been reported to obtain CuO.
