杀线植物资源防治植物寄生线虫病的作用机制及其应用

Mechanism and application of plant resources against plant-parasitic nematodes

我国植物寄生线虫病已经发展成仅次于真菌病害的第二大植物病害,防治难度极大。随着我国农业可持续发展的需求,一些高毒高效化学农药不断被禁用,导致可供选择化学杀线虫剂的产品非常有限,进而杀线植物资源备受广大线虫学者的关注。本文综述了具有杀线虫作用的植物资源,如根系分泌物、组织提取物等活性物质,对植物寄生线虫的作用机制及生产实践中对这些资源的应用情况,并针对目前存在的问题和对未来的研究趋势提出了展望,以期为具有杀线虫作用的植物及其资源的开发和应用提供材料、思路和理论依据。

Plant-parasitic nematodes have developed into the second largest plant disease after fungal disease in China,and its control is extremely difficult.With the demand for sustainable development of agriculture in China,some highly toxic and efficient chemical pesticides are gradually banned,resulting in limited options for chemical nematicides.As a result,the nematicidal plant resources have been widely concerned by nematologists.This article reviewed plant resources with nematicidal effects,such as root exudates,tissue extracts and active substances,the mechanisms of action against plant parasitic nematodes,and the utilization of these resources in production practice.In response to current problems and future research trends,prospects are proposed to provide materials,ideas,and theoretical basis for the development and application of plants and their resources with nematicidal effects.
