Efficacy of green synthesized silver nanoparticle, plant powders and oil against rice weevil Sitophilus oryzae L. (Coleoptera: Curculionidae) on sorghum seeds

Abstract

Synthesis of nanomaterials involves various routes including physical, chemical and biological approaches. The biological green route was chosen to prepare silver nanoparticles from silver nitrate using Moringa oleifera F. (Moringaceae) leaf extract and Botanicals also severely in the stored product pest management. The present study was focused on the insecticidal activity of synthesized silver nanoparticles and botanical powder against Sitophilus oryzae. L. The maximum mortality of S. oryzae was observed with sweet flag rhizome AgNPs (100%), sweet flag rhizome powder (100%), Pungam oil (98.66%) and check Malathion (98.0%) 15 days after treatment. The effect of plant powder and AgNPs on germination of seed was also observed by germination test.
