Abstract Background A pot experiment was conducted to evaluate the phytotoxic thresholds of zinc oxide (ZnO NPs), iron (FeO copper (Cu and silver nanoparticles (Ag NPs) on cotton. All were biosynthesized from Conocarpus erectus L. leaf extract. They characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transmission infrared spectroscopy (FTIR). Five concentration...
