Update on potato diseases in Russia
A study was carried out in Russia in 2015-2018. Potato (Solanum tuberosum) samples were collected from commercial fields in 11 regions. Analysis of 1025 leaf and 725 tuber samples confirmed the earlier reported data on the dominance of potato viruses Y, S, and M in most regions of European Russia, as well as relatively high incidences of Clavibacter michiganensis subsp. sepedonicus (EPPO A2 List), Pectobacterium atrosepticum, and P. carotovorum subsp. carotovorum.
The following records are new for the EPPO Secretariat:
- Ralstonia solanacearum (EPPO A2 List) was detected in two samples from Kostroma region (Central Russia). This is the first documented report for Russia.
- Clavibacter michiganensis subsp. sepedonicus (EPPO A2 List) in Eastern Siberia (Irkutsk region).
- Dickeya dianthicola (EPPO A2 List) in Eastern Siberia (Irkutsk region).
- Potato spindle tuber viroid (Pospiviroid, PSTVd - EPPO A2 List) in Eastern Siberia (Irkutsk region).
- Potato mop-top virus (Pomovirus, PMTV) in Central Russia (Leningrad region), Southern Russia (Samara region) and Eastern Siberia (Irkutsk).
