Article 18(2)

SCHEDULE 11 SPECIAL MEASURES FOR THE CONTROL OF POTATO WART DISEASE(COUNCIL DIRECTIVE 69/464/EEC)(OJ No. L323, 24.12.69, p.1)

1.  When an occurrence of Synchytrium endobioticum(Schilb.) Perc., the pathogenic agent of Potato Wart Disease, is recorded, the appropriate Plant Protection service shall demarcate the contaminated plot and a safety zone large enough to ensure the protection of the surrounding areas. A plot shall be regarded as being contaminated when symptoms of Potato Wart Disease have been found on at least one plant from the plot.

2.  Subject to item 7 of this Schedule, the appropriate Plant Protection Service shall ensure that potato tubers and haulms which came from the contaminated plots be treated in such a way that the plant pest is destroyed. If it is not possible to determine the place from which the contaminated tubers and haulms came then the whole of the batch containing the affected tubers and haulms shall be appropriately treated.

3.  Subject to item 7 of this Schedule, once a contaminated plot has been demarcated:

(a) no potatoes shall be grown thereon;

(b) no plants or planting material intending for transplanting shall be grown thereon, stored in the ground or otherwise.

4.  Subject to item 7 of this Schedule, potatoes may be grown in the safety zone only if they are of a variety which is resistant to the races of Synchytrium endobioticum found on the contaminated plot. A potato variety shall be considered resistant to a particular race of Synchytrium endobioticum when it reacts to contamination by the pathogenic agent of that race in such a way that there is no danger of secondary infection.

5.  The measures taken to control Potato Wart Disease or to prevent it from spreading shall be revoked only if Synchytrium endobioticum is no longer found to be present.

6.  Subject to item 7 of this Schedule, no person shall hold cultures of Synchytrium endobioticum.

7.  An inspector may authorise exemptions from the measures referred to in items 2, 3, 4 and 6 of this Schedule for scientific purposes, tests and selection work provided that such exemptions do not prejudice the control of Potato Wart Disease and create no risk of the spread of this disease.

8.  Additional or stricter measures as may be deemed necessary for the control of Potato Wart Disease or to prevent its spread may be taken, or required by notice to be taken, in accordance with Article 22 or 23.
