作物根结线虫病害综合防治技术概述

根结线虫Meloidogyne spp. 是严重威胁农业生产的重要病原生物，对世界上大多数作物都存在负面影响。在我国，随着保护地栽培模式的扩大及作物复种指数的不断提高，根结线虫病的发生日趋严重，而目前的管理措施尚不能完全控制根结线虫的危害。使用化学杀线虫剂仍然是目前防治根结线虫最常见的短期管理策略。本文总结了目前我国作物根结线虫病的发生现状，介绍了生产中防治该病害的主要化学药剂，分析了其化学防治存在的主要问题，并讨论了目前化学杀线虫剂及其应用技术的优化；展望了未来根结线虫化学防治的研究方向；提出根结线虫的化学防治应该与其他管理措施相结合，实现根结线虫高效、安全、可持续发展的综合治理。

Parallel adaptations and common host cell responses enabling feeding of obligate and facultative plant parasitic nematodes

Root-knot nematodes (Meloidogyne spp.) are important pathogens that seriously harm agricultural production and negatively affect almost every crop in the world. In China, root-knot nematodes are becoming more and more serious with the expansion of protected cultivation and the continuous increase of crop multiple cropping index. Current management practices are not enough to completely control root-knot nematodes. Chemical nematicides are still the most common short-term management strategy for root knot nematodes. In this review, the recent research progresses of the current occurrence of root-knot nematodes and control agents were summarized, including the main problems in the chemical control and the optimization of chemical agents and application technology. The outlook for the development of chemical control methods against root knot nematodes was envisaged: chemical control of root-knot nematodes should be combined with other management strategies to achieve efficient, safe and sustainable integrated management.
