Abstract： Seed coating agents， as a novel type of pesticide formulation， encapsulate dry or moist seeds within a pesticide composite through adhesives， forming a protective film with specific functions and certain strength on the seed surface. Their primary components include active ingredients （such as pesticide materials，micro-fertilizers， etc.） and inactive ingredients （such as film-forming agents and other adjuvants），with film-forming capability being a distinctive feature. This review summarizes the latest research advances in the composition of seed coating agents，seed coating technologies，and their applications in crop health regulation. Seed coating technologies encompass types such as seed dressing， film coating，and pelleting，of which， coating processes including rotary drum coating，spray coating，and fluidized bed coating. Furthermore，it elaborates in detail on the core functions of components like fungicides， insecticides，plant growth regulators， trace elements，and beneficial microorganisms in seed coating agents for crop health regulation， including disease and pest control， growth promotion and yield increase，and stress resistance enhance. The paper also provides an in-depth analysis of the major challenges in this field and proposes that future development of seed coating technologies should toward environmental friendly，low-toxicity，and low-residue， particularly developing biodegradable materials and natural ingredients to improve the safety and efciency of seed coating agents.
