Abstract
The production of Oryza sativa (rice) which is one of the most important food crops is greatly limited by nematode
infestations. While various integrated control measure which include the application of synthetic nematicidal agents have
been adopted, success without some major setback has been elusive. Thus, the need for concerted worldwide intensive
research for safer alternatives has become imperative. Silver nanoparticles (NPs) of Eucalyptus officinallis were prepared
via green synthesis approach. The nanoparticles obtained were subjected to UV-Vis and FT-IR spectroscopies for the
absorption and functional groups characterisations respectively. Surface Plasmon Resonance (SPR) was achieved at
451nm, indicating the formation of NPs and the FTIR showed functional groups which further confirmed the formation
of nanoparticles. The NPs significantly (p=0.05) reduced nematode population in root and soil, increased vegetative
growth of rice plant, with a significant corresponding increase in yield. The plant-based nematicidal agent of silver
nanoparticles origin cheaply prepared in this study adds credence to claim that bio-nematicides holds promise as a costeffective, efficient and eco-friendly option for the future.
