First report of Strawberry pallidosis associated virus infecting strawberry in China.
A survey of viral diseases on strawberry was carried out during the spring of 2017 in Henan Province, China. In the survey, 4 strawberry fields in Zhengzhou were investigated, and the leaves showing yellowing, mosaic and interveinal chlorosis were observed on strawberry plants, though the disease incidence was relatively low during the investigation. Six symptomatic samples were collected for virus identification. The presence of Strawberry pallidosis-associated virus (SPaV) was detected on the symptomatic samples based on various molecular analyses. This is thought to be the first report of a natural infection of SPaV on strawberry in China.
