PVT is shown to be pollen- and seed-borne and is transmitted by inoculation of sap. Healthy potato plants pollinated with pollen from infected plants showed no virus transmission (PVT000-3). Documentation shows transmission via tubers but no evidence shows seed as a natural pathway. EPPO notes it may be spread by true potato seed (TPS) through the movement of potato germplasm, although the significance of this in practice is less clear since it has only been rarely reported infecting gene bank accessions. Multiple sources note PVT is readily transmitted mechanically.
