Pseudoperonospora humuli is an obligate biotrophic oomycete that causes downy mildew, one of the most devastating diseases of cultivated hop, Humulus lupulus. Downy mildew occurs in all production areas of the crop in the Northern Hemisphere and Argentina. The pathogen overwinters in hop crowns and roots, and causes considerable crop loss. Downy mildew is managed by sanitation practices, planting of resistant cultivars, and fungicide applications. However, the scarcity of sources of host resistance and fungicide resistance in pathogen populations complicates disease management. This review summarizes the current knowledge on the symptoms of the disease, life cycle, virulence factors, and management of hop downy mildew, including various forecasting systems available in the world. Additionally, recent developments in genomics and effector discovery, and the future prospects of using such resources in successful disease management are also discussed.

啤酒花霜霉病菌Pseudoperonospora humuli

Pseudoperonospora humuli是一种专性生物营养卵菌，会导致霜霉病，这是栽培啤酒花的最具破坏性的疾病之一，Humulus lupulus. 霜霉病发生在北半球和阿根廷的所有作物产区。病原体在啤酒花冠部和根部越冬，造成大量作物损失。霜霉病是通过卫生措施、种植抗病品种和使用杀菌剂来控制的。然而，病原体种群中宿主抗性和杀菌剂抗性来源的稀缺使疾病管理复杂化。本综述总结了目前关于啤酒花霜霉病的症状、生命周期、毒力因素和管理的知识，包括世界上可用的各种预测系统。此外，还讨论了基因组学和效应子发现的最新进展，以及在成功疾病管理中使用此类资源的未来前景。
