Interpretive Summary:

Technical Abstract: Pesticide efficacy is limited by evaporation and precipitation. These processes can result in the need for costly pesticide re-application. By using a nanocapsule to contain the pesticide, these two problems can be greatly reduced. Produced nanocapsules adsorb on the surface of the plant and are not washed away by rain. In this study, menthol and peppermint oils were chosen as model systems because they are considered to be minimum-risk pesticides. Pesticides were encapsulated into the shell prepared from protein and degradable polymer, poly(ethyl cyanoacrylate). The size of prepared nanocapsules was smaller than 200 nm and readily adsorbed onto the hydrophobic surfaces. The protocol of this technique can readily be modified to accommodate various types of pesticides.
