Abstract: Duo to their advantages of small particle size, easy size adjustment, rich diversity and good mobility, nanomaterials have attracted wide attention as effective carriers in pesticide delivery systems and agricultural pest control. Nanomaterials and technologies have shown great potential in improving the bioavailability, solubility and slow-release properties of pesticide formulations. This paper summarized the research progress in the development of functional nanopesticide delivery systems using nanomaterials and technologies, systematically reviewed the intelligent-responsive pesticide controlled-release formulations that accurately release pesticide active ingredients, and different functional nanopesticide delivery systems such as leaf affinity, soil adsorption and pesticide dual loading systems. The effects of nanopesticide delivery system on pesticide reduction, efficiency enhancement and precise application were summarized, and the application scenarios and industrialization potential of functional nanopesticide delivery system were prospected.
