| description | <em>Mangifera</em> <em>indica</em> is an important commercial fruit of India and primary food source for the mango leafhopper, <em>Amritodus</em> <em>brevistylus</em> further leading to the development of its associated fungus, <em>Aspergillus</em> <em>niger</em>. The present study was done to assess the antifungal and insecticidal activity of biologically synthesized silver nanoparticles using peel extracts of <em>Raphanus</em> <em>sativus</em> (Brassicaceae). <em>Raphanus sativus</em> peel extract is effective in extracellular reduction of Ag ions and capping the synthesized nanoparticles avoiding further agglomeration. The synthesized AgNPs are characterized by UV-vis spectroscopy, X-ray diffraction analysis, fourier transform infrared spectroscopy, scanning electron microscopy and energy dispersive x-ray analysis. Biologically synthesized AgNPs exhibited significant toxicity (LC50 − 7.61 ppm/48h) over mango leafhopper, <em>Amritodus</em> <em>brevistylus</em>. Silver nanoparticles synthesized using <em>Raphanus</em> <em>sativus</em> is also effective against the fungal pathogen, <em>Aspergillus</em> <em>niger</em> (developed on the infestations of mango leafhopper, <em>Amritodus</em> <em>brevistylus</em>) showing very strong inhibitory zone (80 mm). |
