羧甲基壳聚糖在植物病虫害防治上的应用

植物病虫害对粮食产量造成巨大影响，壳聚糖（Chitosan， CS）及其衍生物具有一定的杀菌、诱导抗性及促生长等性能，被广泛应用于植物保护.对羧甲基壳聚糖（Carboxymethyl chiston， CMCS）的合成、植物保护活性及其作用机制进行了简单介绍，对其在植物侵染性和非侵染性病害以及虫害防治上的应用进行了综述，对其自身存在的一些局限性进行了探讨，并对其在植物病虫害防治上的应用前景进行了展望.

Application of carboxymethyl chitosan in plant diseases and pest control

Plant diseases and pests have a huge impact on food production. Chitosan and its derivatives are widely used in plant protection for their sterilization, induced resistance and growth-promoting properties. The synthesis, plant protective activity and action mechanism of carboxymethyl chitosan were briefly introduced. Its applications in plant infectious and non infectious diseases and pest control were reviewed. Some limitations of its own existence as well as its application prospects in plant diseases and pest control were discussed too.
