摘　　要：基于传统农药剂型存在理化性质不稳定、利用率低、持效期短以及环境问题凸显等不足,开发释放剂量可控、安全性高的农药控释剂已成为目前农药研究的热点。天然高分子材料因具有无毒无害、来源丰富、廉价易得且生物降解性好等特点而成为农药控释剂的理想载体。本文综述了淀粉、纤维素、壳聚糖和木质素4种自然界中含量丰富的天然高分子材料在农药控释剂中应用的研究进展,并展望了其发展前景。Given the problems associated with traditional pesticide formulations, such as unstable physicochemical properties, low utilization rate, short effective duration and environmental issues, the development of safe and controlled release pesticide formulations has become a hot research topic.Natural polymer materials are excellent carriers for controlled release of pesticides, because of their non-toxicity, extensive sources, low cost and good biodegradability. In this review, the research progress of four abundant natural polymers(i.e. starch, cellulose, chitosan and lignin) in controlled release pesticides was summarized, and the development prospects were provided.
