Abstract :

Today, Water base nanopesticides with small size can help to over comes the low solubility of pesticides to control pest in agriculture. In this paper, an oil-core silica/ polymer/ fipronil shell nanoparticles was prepared for insecticidal activity of fipronil in vitro was tested against termite (Microcerotermes diversus Silvestri (Isoptera: Termitidae)), which, the result of the biological activity showed the effectiveness of fipronil nanparticles during 72 h at 15 ppm and make tunneable activity of fipronil insecticide.
