Situation of Ralstonia solanacearum in Russia
In the 1980s, in the publications of the All-Russian Institute of Phytopathology, there were reports indicating the possible presence of Ralstonia solanacearum (EPPO A2 quarantine pest) in several regions of Russia (northwest chernozem region (Kaliningrad, Moscow and Voronej), Krasnodar territory, Far East, Urals and Siberia).
Today, however, the presence of R. solanacearum has not been confirmed in these regions. In 1999, a single case was confirmed in the region of Leningrad in one small plot of 0.06 ha of potato cultivar Sante. However, it is noted that a country-wide monitoring programme is needed to ascertain the present situation of R. solanacearum in Russia.
