Biosynthesis, Characterization, Nematicidal Efficacy of Silver Nanoparticles Synthesized using Solanum nigrum Fruit against Root Knot Nematode Meloidogyne incognita

The present study to synthesis Sliver nanoparticles by using fruit extract of European black nightshade (Solanum nigrum) and to test their characterized along with their potentiality to control the Meloidogyne incognita at different concentration. The synthesized AgNPs were characterized by UV-Vis Spectroscopy, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction analysis (XRD). The synthesized AgNPs result of UV-Spectroscopy and the strong broad peak located at 443 nm. In SEM analysis, the synthesized silver nanoparticles was clearly seen that in a spherical shape. The size of AgNPs range is 30 nm. In FTIR analysis, IR bands of synthesised AgNPs observed functional groups are methyl, methylene and methoxy groups, secondary amines and vinyl groups. In XRD analysis, the average size of AgNPs particles is 29 nm and are crystalline in nature. In nematicidal activity of AgNPs on M. incognita at different concentrations the percent mortality caused by 2.5 µg/ml (100%) of AgNPs was higher than the percent mortality caused by 0.5 µg/ml (48%) of AgNPs.
