Nanotechnology is gaining more attraction in various fields, including Agriculture. Green synthesis of nanoparticles has emerged as a simple, viable, and alternative eco-friendly method for nanoparticle synthesis when compared with the chemical method. In the present study, Copper nanoparticles have been synthesized using aquatic weed Kappaphycus alvarezii extract, and characterization was done. The synthesized nanoparticles exhibited maximum absorption at 630 to 650nm, which is (SPR) for Copper nanoparticles. The Copper nanoparticles were characterized based on Scanning Electron Microscopy (SEM) and whose size was found to be in the ranges from 40 to 80nm. The XRD analysis of synthesized copper nanoparticles showed four peaks at 35.5, 38.6, 48.5, 61.5, and 68.02 angles it confirms the presence of Copper nano. The antifungal activity of the Copper nanoparticles was checked against Colletotrichum capsici at different concentrations, i.e., 10, 25, 50, 100, 200, 400, and 600ppm, in which the significant zone of inhibition was observed on PDA amended with 100ppm of copper nanoparticles in vitro. Further, the same resulted in reduced sporulation and Mycelial growth to a greater extent. This has promised that the newly synthesized Copper nanoparticles could be used as an antifungal agent for crop disease management, especially in the case of anthracnose.
