Abstract

Abstract:

In recent years, a series of breakthrough advances of nano-technology have been made in the field of plant disease and pest control, providing strong technological support for efficient agricultural production and sustainable development. This review systematically outlines the research progress of nano-technology in pesticide controlled-release, with a focus on summarizing the current status of four categories of carrier materials: polymeric, inorganic non-metallic, metallic, and bio-based carriers; highlights the advantages of these carriers in terms of pesticide loading efficiency, controlled-release performance, and environmental responsiveness; special emphasis is placed on analyzing the mechanisms and application potential of representative materials such as polysaccharides, mesoporous silica, and metal-organic frameworks, offering insights for the development of efficient, eco-friendly, and intelligent nano-pesticides. The results show that: (1) all kinds of carriers can improve the stability and targeting of pesticides. The drug loading rate of mesoporous silica and metal organic frameworks can reach 33.58%-46.27%, and they have environmental response release ability such as pH and temperature. (2) Nano-pesticides can reduce the degradation rate of pesticides (the degradation rate is reduced by more than 20% after 52 h UV irradiation), improve the control effect on target organisms, and reduce environmental risks. (3) The review identifies existing challenges in nano-pesticide development, including complex fabrication processes, relatively high costs, insufficient drug-loading capacity, and unresolved ecological safety concerns. Recommendations are proposed to further enhance the functional design of carrier materials, advance research on low-cost green synthesis technologies, and establish comprehensive safety evaluation systems to promote the large-scale application and adoption of nano-pesticides in sustainable agriculture.

Key words: nanomaterials, insecticides, nanocarriers, controlled release, safe agriculture
