Silver nanoparticles were synthesized from silver sulfate by using the chemical reduction method with dextran as both a reducing agent and a protective agent. The influence of reaction temperature, time, and initial pH on the synthesis was investigated. The formation of Ag nano-particles (AgNPs) and their morphology were characterized with UV-Vis spectroscopy, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, and Fourier transform-infrared spectroscopy. The antifungal and antibacterial effects of AgNPs/dextran on Xanthomonas oryzae and Pyricularia oryzae were tested.
