Results of the 2002/2003 survey on Potato spindle tuber pospiviroid in France: eradication has been achieved
The NPPO of France recently informed the EPPO Secretariat of the results of the 2002/2003 survey on Potato spindle tuber pospiviroid (EPPO A2 quarantine pest). It can be recalled that a few findings had been made in 2001 (see EPPO RS 2002/145). Surveys were done in the areas where PSTVd had been found. All potato material from these areas, either grown under glasshouse or in the field, was tested. All potato lots (i.e. 387 potato lots corresponding to more than 8,000 tests) gave negative results. In addition, surveys were done to verify the absence of PSTVd from the French production of seed potatoes. Therefore tests were also done on potato material from the national collection (located at Hanvec, Bretagne), from collections of 3 regional centres of seed potato production, and also on 10% of seed potato lots (B1 to B4 seed potato lots produced in 2002). In total, more than 4,500 tests were performed and all results were negative.
The declared status of Potato spindle tuber pospiviroid in France is: Absent, eradicated.
