Plant-parasitic nematodes (PPNs) constitute the most damaging group of plant pathogens. Plant infections by root-knot nematodes (RKNs) alone could cause approximately 5% of global crop loss. Conventionally, chemical-based methods are used to control PPNs at the expense of the environment and human health. Accordingly, the development of eco-friendly and safer methods has been urged to supplement or replace chemical-based methods for the control of RKNs. Using microorganisms or their metabolites as biological control agents (BCAs) is a promising approach to controlling RKNs. Among the metabolites, volatile organic compounds (VOCs) have gained increasing attention because of their potential in the control of not only RKNs but also other plant pathogens, such as insects, fungi, and bacteria. This review discusses the biology of RKNs as well as the status of various control strategies. The discovery of VOCs emitted by bacteria from various environmental sources and their application potential as BCAs in controlling RKNs are specifically addressed.
植物寄生线虫（PPNs）是最具破坏性的植物病原体群体之一。仅根结线虫（RKNs）对植物的感染就可能导致全球约 5%的作物损失。传统上，人们使用基于化学物质的方法来控制 PPNs，但这会对环境和人类健康造成影响。因此，人们迫切需要开发环保且更安全的方法来补充或替代基于化学物质的方法，以控制 RKNs。将微生物或其代谢物用作生物防治剂（BCAs）是控制 RKNs 的一种很有前途的方法。在这些代谢物中，挥发性有机化合物（VOCs）由于其不仅可以控制 RKNs，还可以控制昆虫、真菌和细菌等其他植物病原体的潜力，因此越来越受到关注。本文综述了 RKNs 的生物学特性以及各种控制策略的现状。特别讨论了从各种环境来源的细菌中发现的 VOCs 及其作为 BCA 控制 RKNs 的应用潜力。
