Bacterial diseases are a constant threat to crop production globally. Current management strategies rely on an array of tactics, including improved cultural practices; application of bactericides, plant activators, and biocontrol agents; and use of resistant varieties when available. However, effective management remains a challenge, as the longevity of deployed tactics is threatened by constantly changing bacterial populations. Increased scrutiny of the impact of pesticides on human and environmental health underscores the need for alternative solutions that are durable, sustainable, accessible to farmers, and environmentally friendly. In this review, we discuss the strengths and shortcomings of existing practices and dissect recent advances that may shape the future of bacterial disease management. We conclude that disease resistance through genome modification may be the most effective arsenal against bacterial diseases. Nonetheless, more research is necessary for developing novel bacterial disease management tactics to meet the food demand of a growing global population.
细菌病是全球作物生产的一个持续威胁。目前的管理策略依赖于一系列策略，包括改进的栽培措施；杀菌剂、植物激活剂和生物防治剂的应用；以及在有抗性品种时使用抗性品种。然而，有效的管理仍然是一个挑战，因为部署的策略的持久性受到不断变化的细菌种群的威胁。对农药对人类和环境健康影响的审查力度的加大，凸显了需要持久、可持续、农民可获得且环保的替代解决方案。在这篇综述中，我们讨论了现有实践的优缺点，并剖析了可能塑造细菌病管理未来的最新进展。我们得出的结论是，通过基因组修饰来提高抗病性可能是对抗细菌病最有效的手段。尽管如此，为了开发新的细菌病管理策略来满足全球不断增长的人口的粮食需求，还需要进行更多的研究。
