It is currently used as the most important and promising approach for protection of host plants against insect pests. Nano-encapsulation includes the use of a different kind of nanoparticles with insecticide. In this process a chemical such as an insecticide is slowly but efficiently released to a particular host plant for insect pest control. Nano-encapsulation with nanoparticles in form of pesticide allows for proper absorption of the chemical into the plants unlike the case of larger particles (Scrins is and Lyons 2007).
