Effectiveness of Silver Nano-particles of Extracts of Urtica urens (Urticaceae) Against Root-knot Nematode Meloidogyne incognita

Abstract

Natural products are an important resource for finding new pesticides. Additionally, preparation of elemental nano-particles of natural products was proven to be promising as anti-microbial agents. Present study aimed to examine the petroleum ether, ethyl acetate and ethanol extracts of Urtica urens and their silver-nano formulations as nematicides against root-knot nematode Meloidogyne incognita. Leaf extracts of U. urens were prepared through successive extraction and the Ag-nanoparticles of extracts and the reference nematicide (rugby) were synthesized. Results revealed that Ag-nano formulations of extracts were effective in the management of M. incognita.
