Keywords: ZnO nanorods, hydrothermal method, antibacterial activity and plant pathogenic bacteria.
Abstract: Nano-ZnO has been successfully synthesized via hydrothermal technique to evaluate as plant pathogenic antibacterial agent. The crystalline and morphological structures of ZnO were examined using X-ray diffraction and scanning electron microscopy respectively. The morphological structure of synthesized ZnO was nano-rod with an average aspect ratio about 8. The antibacterial effect of ZnO nanorods on eight different hetero soft root plant pathogenic bacteria was investigated for inhibition and reduction the cell growth of examining strains using disc diffusion method. The minimum inhibitory concentrations of nanorods ZnO towards plant pathogens microbes were explored. The recorded inhibition zones using ZnO were ranged between 14 to 32 mm compared with 0 to 24 mm for antibiotics.
