Plant pathogens as quarantine pests in Russia and
RS 95/002 recently presented the new quarantine lists of Russia. Specific information is now available on the plant pathogens of this list. In general, the A1 pests have not been recorded in Russia or in any part of the former USSR. However, the following isolated occurrences may be noted:
- Diaporthe phaseolorum var. caulivora: isolated foci in 1986/1989 in Krasnodar territory (far south of Russia) and Abkhazia (Georgia). Not established.
- Didymella ligulicola: intercepted in quarantine nurseries.
- Erwinia amylovora: outbreak in Armenia in 1989 (already reported in 506/08). No records in former USSR since.
- Grapevine flavescence dorée MLO: suspicious symptoms seen in Moldova and Ukraine but disease not positively identified.
For the A2 pathogens, the positions can be summarized as follows:
- Diaporthe helianthi: Stavropol territory (far south of Russia), Belgorod province (North of border with Ukraine), also Moldova, Ukraine.
- Synchytrium endobioticum: many regions of Russia, Baltic states, Belarus, Ukraine, a few foci in Armenia.
- Cochliobolus heterostrophus race T: Krasnodar and Stavropol territories (North Caucasus), Kabardin-Balkar and Chechen-Ingush autonomous republics (Caucasus).
- Plum pox potyvirus: Krasnodar and Stavropol territories (North Caucasus), Volgograd and Rostov provinces (South Russia).
The Russian list also covers 'potentially dangerous pathogens for Russia'; mostly of A1 type. A few have an A2 type of distribution:
- Phomopsis viticola: Krasnodar territory (North Caucasus), Ukraine, Georgia, Moldova.
- Eutypa lata (= E. armeniacae): Moldova and Ukraine
