农药缓释颗粒剂载体材料类型及应用研究进展

Types of carrier materials and application research progress of pesticide controlled-release granules

随着功能材料、缓释技术以及加工工艺的不断发展,传统农药剂型颗粒剂焕发出新的生机,基于防治场景的省力化、精简化、功能型颗粒剂不断涌现。在中国农业农村部提出农药零增长行动方案的背景下,发展缓释颗粒剂是当前提高农药利用率的一个重要且有前景的方向。本文按照颗粒剂的制备工艺进行分类,综述了不同类型颗粒剂的制备原理、载体材料类型、选择原理及应用研究进展,并对缓释颗粒剂的发展前景进行了展望,可为农药颗粒剂的制备及载体材料的选择提供参考。

As the continuous development of functional materials,controlled-release technology and processing technology,the traditional pesticide formulation granules radiate new vitality.Based on prevention scenes,labor-saving,efficient and multifunctional granules are constantly emerging.In the context of Zero Growth of Chemical Fertilizer and Pesticide Use proposed by the Ministry of Agriculture and Rural Affairs of the People’s Republic of China,the development of controlled-release granules is an important and promising direction for improving the utilization rate of pesticides.According to the different preparation technology,granules can be divided into five types.This review has summarized the preparation principles,carrier materials,application progress and the selection principles of carrier materials of different types of controlled-release granules,and the prospect of controlled-release granules was proposed,which could provide a reference for the preparation of pesticide granules and the selection of carrier materials.
