The eco-friendly production of nanoparticles from plant extracts has garnered considerable interest for their dual function as stabilizing and reducing agents. This work biogenically generated copper chromite (CuCr2O4) nanocomposites utilizing Mangifera indica (mango) pulp extract, highlighting their potential in antibacterial and photocatalytic applications. The synthesized CuCr2O4 nanocomposites displayed agglomerated grains with an average particle size of 47.5 nm, as verified by TEM imaging, and a BET surface area of 7.948 m2/g. FTIR spectroscopy confirmed the establishment of Cu–O and Cr–O bonds, while UV–vis spectroscopy assessed an indirect bandgap of 2.99 eV, enhancing the material’s photocatalytic efficacy. Antimicrobial experiments demonstrated potent antifungal and anti-nematic properties, substantially suppressing Sclerotinia sclerotiorum and Meloidogyne incognita at doses ranging from 100 to 300 ppm. Moreover, the photocatalytic breakdown of methylene blue under solar irradiation exhibited a 90% efficiency after 90 min, underscoring the nanocomposite’s efficacy in organic dye elimination. These results highlight the adaptability of CuCr2O4 nanocomposites as eco-friendly substitutes for agricultural pest management and wastewater treatment, reducing dependence on toxic chemicals while facilitating environmental restoration.
