Macleaya cordata is a perennial herb that belongs to the family Papaveraceae and, as a commercial crop, is widely used in the livestock industry. Root rot disease is one of the most serious diseases of M. cordata. In June 2017, a brown root rot was observed on M. cordata, cv. HNXN-001 in 10 commercial fields in Hunan Province, China. The fields varied from 1000 m2 to 3500 m2, with approximately 8% of plants affected. Symptoms included withering, leaf chlorosis, brown rot of the root tips or lateral roots, and internal decay of the taproots leading to plant death. Fusarium oxysporum Schlecht. was isolated and identified on the basis of morphology and ITS rDNA and EF-1α gene sequencing. This is the first report of root rot of M. cordata caused by F. oxysporum in China. Detection of F. oxysporum on diseased M. cordata roots is important for M. cordata root rot control.
