致病疫霉会导致马铃薯和西红柿晚疫病，对农业产生重大经济影响。晚疫病的防治在很大程度上依赖于合成杀菌剂的应用，这并不是可持续农业和环境安全的最终解决方案。生物防治策略有望成为综合害虫管理（IPM）计划中控制植物病害的传统化学品的替代方法。经过充分研究的针对致病疫霉的生物防治剂包括真菌、卵菌、细菌和这些拮抗剂产生的化合物，以及植物产生的某些生物活性代谢物。实验室和温室实验表明在实际晚疫病管理中使用生物防治的潜力。然而，由于功效低且不稳定，生物防治向现场应用的过渡目前存在问题。在这篇综述中，我们对这些生物防治策略及其潜在的相应机制进行了全面的总结。为了更直观地了解农业系统中针对致病疫霉的有前景的生物防治剂，我们根据这些拮抗剂的分类学分类讨论了它们的用途、作用方式和未来潜力。为了实现生物防治剂产生最佳效果的目标，建议开展田间试验、菌株改良、配方、法规和应用优化。具有不同作用模式或生物适应特性的组合生物防治剂可用于增强生物防治功效。更重要的是，生物防治剂的应用应与 IPM 计划中其他现有和即将推出的方法相协调。© 2023 化学工业协会。

A review of biocontrol agents in controlling late blight of potatoes and tomatoes caused by Phytophthora infestans and the underlying mechanisms

Phytophthora infestans causes late blight on potatoes and tomatoes, which has a significant economic impact on agriculture. The management of late blight has been largely dependent on the application of synthetic fungicides, which is not an ultimate solution for sustainable agriculture and environmental safety. Biocontrol strategies are expected to be alternative methods to the conventional chemicals in controlling plant diseases in the integrated pest management (IPM) programs. Well-studied biocontrol agents against Phytophthora infestans include fungi, oomycetes, bacteria, and compounds produced by these antagonists, in addition to certain bioactive metabolites produced by plants. Laboratory and glasshouse experiments suggest a potential for using biocontrol in practical late blight disease management. However, the transition of biocontrol to field applications is problematic for the moment, due to low and variable efficacies. In this review, we provide a comprehensive summary on these biocontrol strategies and the underlying corresponding mechanisms. To give a more intuitive understanding of the promising biocontrol agents against Phytophthora infestans in agricultural systems, we discuss the utilizations, modes of action and future potentials of these antagonists based on their taxonomic classifications. To achieve a goal of best possible results produced by biocontrol agents, it is suggested to work on field trials, strain modifications, formulations, regulations, and optimizations of application. Combined biocontrol agents having different modes of action or biological adaptation traits may be used to strengthen the biocontrol efficacy. More importantly, biological control agents should be applied in the coordination of other existing and forthcoming methods in the IPM programs. © 2023 Society of Chemical Industry.
