Valeriana officinalis is a host of tomato spotted wilt tospovirus

In Italy, Valeriana officinalis is grown for medicinal or ornamental purposes. During a survey on medicinal and aromatic plants, two field crops of V. officinalis in Emilia-Romagna and Liguria showed mosaic, vein clearing, leaf crinkle, chlorotic-necrotic rings and necrosis of veins and stems. Tomato spotted wilt tospovirus (EPPO A2 quarantine pest) was detected by ELISA, biological tests and electron microscopy in diseased plants. This is apparently the first report of tomato spotted wilt tospovirus on Valeriana officinalis.
