Chemical nematicide is the most common method of controlling plant-parasitic nematodes (PPN). Given the negative impact of chemical nematicides on the environment and ecosystem, it is necessary to seek their alternatives and novel modes of application. Chitin oligo/polysaccharide (COPS), including chitosan and chitosan oligosaccharide, has unique biological properties. By producing ammonia, encouraging the growth of antagonistic bacteria, and enhancing crop tolerance, COPSs help suppress PPN growth during soil remediation. COPS is also an effective sustained-release carrier that can be used to overcome the shortcomings of nematicidal substances. This review summarizes the advancements of COPS research in nematode control from three perspectives of action mechanism as well as in slow-release carrier-loaded nematicides. Further, it discusses potential agricultural applications for nematode disease management.
化学杀线虫剂是防治植物寄生线虫（PPN）最常用的方法。鉴于化学杀线虫剂对环境和生态系统的负面影响，有必要寻找其替代品和新的应用方式。几丁质寡糖/多糖（COPS），包括壳聚糖和壳寡糖，具有独特的生物学特性。通过产生氨、促进拮抗细菌生长以及增强作物耐受性，COPS在土壤修复过程中有助于抑制PPN的生长。COPS也是一种有效的缓释载体，可用于克服杀线虫物质的缺点。本文综述了从作用机制以及载于缓释载体中的杀线虫剂这三个角度对COPS在防治线虫方面的研究进展。此外，还讨论了其在防治线虫病害方面潜在的农业应用。
