Potato virus S (PVS) is a plant pathogenic virus. It was first reported in Netherlands. PVS causes mild or no symptoms in most potato varieties. It is common in potatoes in many regions and does not cause significant yield losses. Field-grown potatoes are not routinely screened for this virus because it is not considered economically important.
