New data on quarantine pests and pests of the EPPO Alert List
By browsing through the literature, the EPPO Secretariat has extracted the following new data concerning quarantine pests and pests included on the EPPO Alert List.
Detailed records
Curtobacterium flaccumfaciens subsp. flaccumfaciens (EPPO A2 quarantine pest), in Canada, had so far been found only in the eastern part of the country. It has now been found in Alberta, in the west (Hsieh et al., 2002).
Glomerella acutata (EU Annexes as Colletotrichum acutatum) was found in western New York, US, in 2000. This is the first report in New York state and the second report in northeastern US (Turechek & Heidenreich, 2002).
Globodera pallida (EPPO A2 quarantine list) was detected in several samples collected from various areas of Czech Republic (no details given) (Promed, 2002). This confirms earlier reports according to the EPPO Secretariat.
Clavibacter michiganensis subsp. sepedonicus (EPPO A2 quarantine list) was found in seed potato farms in Prince Edward Island, Canada. The seed crops concerned can only be sold for consumption or processing. A major disinfection programme is being implemented and infested land is being removed from seed production for two years. (Promed, 2002).
Phakopsora euvitis (EPPO Alert List) was found in Northern Territory, Australia, in 2001. It is considered as a very serious threat to commercial vineyards, and severe measures have been taken in Northern Territory to avoid its spread to the main grapevine-growing regions of Australia. Eradication measures include inspection of grapevine plants in gardens, destruction of infected plants and neighbouring plants.
