The routine and the most effective method of viruses elimination from potato plants is in vitro culture of apical shoots combined with thermo- and/or chemotherapy. At times electrotherapy or cryotherapy is also applied. Elimination of potato viruses by thermotherapy required treatment of infected plants with high temperature (35°C - 45°C) for about two weeks. Thermotherapy is useful for elimination of PLRV and PVY from potato plants. In chemotherapy antimetabolite, like ribavirin is used. Chemotherapy is dedicated for elimination of PVM, PVS and PVX. Very often the successful virus elimination require a few cycles of thermo- and/ or chemotherapy.
