Green synthesis of copper bionanoparticles to control the bacterial leaf blight disease of rice

Copper bionanoparticles were successfully synthesized using leaf aqueous extract of Datura innoxia from copper sulphate. Nanoparticles were characterized with the help of UV-Vis spectroscopy, Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy and Fourier Transform Infrared Spectroscopy. FESEM analysis showed that the particles were spherical in shape with size ranging from 5 to 15 nm. The antimicrobial activity of copper bionanoparticles revealed that they are effective growth inhibitors against Xanthomonas oryzae pv. oryzae, the causative organism of bacterial leaf blight of paddy.
