摘要

在对一种来自巴西的禾状杂草——酸草(Digitaria insularis)的真菌群进行调查时，在米纳斯吉拉斯州不同地方的植物上观察到严重的叶枯病症状。经过ITS、GPDH和TEF-1α基因的多相分析，从病组织中分离出一种真菌，鉴定为山田双北极星。通过接种健康植株，证实了对酸草的致病性。这是巴西和世界范围内首次报道山田白僵菌引起岛叶枯病的报道。

Bipolaris yamadae causes foliage blight of Digitaria insularis in Brazil

During a survey of the mycobiota of sourgrass (Digitaria insularis), a graminaceous weed from Brazil, severe foliage blight symptoms were observed on plants at different places of the state of Minas Gerais. A fungus identified as Bipolaris yamadae, after a polyphasic study, including analysis of ITS, GPDH and TEF-1α genes, was isolated from diseased tissues. Pathogenicity to sourgrass was confirmed through inoculations of healthy plants. This is the first report of B. yamadae causing foliage blight on D. insularis in Brazil and worldwide.
