This invention relates to the fields of pesticide formulations and pesticide pest control, specifically to a composite nano-slow-release suspension of emamectin benzoate and chlorantraniliprole, its preparation, and application. The nano-slow-release suspension comprises emamectin benzoate, chlorantraniliprole, a nanocarrier, a wetting agent, a dispersant, a synergist, a thickener, an antifoaming agent, an antifreeze, a preservative, and water. The nanocarrier is an NX-CMCS & MOF composite nanocarrier. Spraying this composite nano-pesticide onto crops improves the adhesion and penetration of the pesticide on leaves, enhances its resistance to rain washout, and effectively kills major crop pests such as bollworms, diamondback moths, cowpea thrips, and rice planthoppers. Compared with traditional pesticide formulations, it has a significant effect of reducing dosage and increasing efficacy, and has broad application prospects in the field of agricultural pest control and promoting green agriculture.
