Abstract: Samples of Erigeron brevisapus root rot in Yunnan were collected and the pathogen was isolated and identified. The results showed that this new disease was caused by Fusarium sporotrichioides, which belong to Tuberculariales of Hyphomycetes in Deuteromycotina. After be infected, the plant appeared wilt in early period and then died. The root had rotted partly or entirely and the vascular became browning. It was the first report of this disease and Erigeron brevisapus was a new described host of Fusarium sporotrichioides.

Key words: Erigeron brevisapus, Root rot, Fusarium sporotrichioides
