Pestalotiopsis-like species are necrotrophic fungi, which infect many annual and perennial crops, including agricultural, horticultural, and plantation crops, in postharvest and under field conditions worldwide. They cause multiple diseases on crops, which results in severe yield loss. At present, Pestalotiopsis-like species cause gray blight on tea, which is a widely prevalent disease in major tea-growing countries and rapidly spreading in other tea-growing countries of minor importance due to climate change. The global increase in disease incidence and severity and the emergence of new virulent isolates have prompted research on the evolution of pathogenic determinants in these fungal species. This review synthesizes the epidemiology, molecular and genetic studies of the gray blight pathogen with particular reference to tea crop and the approaches to mitigate it. Further, the adaptation of Pestalotiopsis-like species on other crops and their management strategies are also discussed along with potential areas for future research.

多盘拟盘菌属样物种是死体营养真菌，其在世界各地的收获后和田间条件下感染许多一年生和多年生作物，包括农业、园艺和种植园作物。它们会给农作物带来多种疾病，导致严重的产量损失。目前，茶多盘拟盘菌属引起的灰疫病是主要茶产国广泛流行的病害，并因气候变化而在其他次要茶产国迅速蔓延。全球疾病发病率和严重程度的增加以及新的有毒菌株的出现促使人们对这些真菌物种的致病决定因素的进化进行研究。这篇综述综合了灰疫病病原体的流行病学、分子和遗传学研究，特别是茶树作物及其缓解方法。此外，还讨论了类多盘拟盘菌属物种对其他作物的适应及其管理策略以及未来研究的潜在领域。
