▎ 摘　　要

NOVELTY - Preparing nano sustained-release pesticide formulation involves dissolving graphene oxide in distilled water, then adding emamectin benzoate and green eco-friendly multi-compound additives, and mixing through a high-speed homogenizer to obtain a nano-release emamectin benzoate stably dispersed in the aqueous phase pesticide formulations. The graphene oxide is one or more mixtures of graphene oxide, reduced graphene oxide, sulfonated graphene oxide, aminated graphene oxide and alkylated graphene oxide. USE - Method for preparing nano sustained-release pesticide formulation in preventing and controlling armyworm (claimed). ADVANTAGE - The method has characteristics of simple process, convenient operation, environmental protection, controllable and slow release, through sustained-release experimental tests, the pesticide formulation has sustained-release performance, and it provides new ideas for reducing pesticide application and increasing efficiency and sustainable agricultural development.
