▎ 摘　　要

NOVELTY - Preparing nano sustained-release pesticide formulation involves dissolving graphene oxide containing graphene oxide, reduced graphene oxide, carboxylated graphene oxide, amino acid modified graphene oxide, aminated graphene oxide, and/or alkylated graphene oxide, in distilled water, adding cyhalothrin and green eco-friendly multi-compound additives, mixing by a high-speed homogenizer, and obtaining product stably dispersed in aqueous phase. USE - Method for preparing nano sustained-release pesticide formulation in controlling of Culex pipiens pallens (claimed). ADVANTAGE - The method provides new ideas for green preparation of pesticide preparations, pesticide application reduction and efficiency enhancement, and sustainable agricultural development.
