Q: This Directive concerns the minimum measures to be taken within the Member States to control Potato Wart Disease and to prevent this cryptogamic disease from spreading. 1.xa0xa0xa0When an occurrence of Synchytrium endobioticum (Schilb.) Perc., the pathogenic agent of Potato Wart Disease is recorded, Member States shall demarcate the contaminated plot and a safety zone large enough to ensure the protection of surrounding areas.2.xa0xa0xa0A plot shall be regarded as being contaminated when symptoms of Potato Wart Disease have been found on at least one plant from that plot. The Member States shall provide that potato tubers and haulms which came from contaminated plots be treated in such a way that the harmful organism is destroyed. If it is no longer possible to determine the place from which contaminated tubers and haulms came, the whole of the batch in which the contaminated tubers or haulms have been found must be treated. The Member States shall provide that on contaminated plots:(a) no potatoes may be grown;(b) no plant intended for transplanting may be grown, stored in the ground or otherwise. 1.xa0xa0xa0The Member States shall provide that in the safety zone potatoes may be grown only if they are of a variety which is resistant to the races of Synchytrium endobioticum found on the contaminated plot.2.xa0xa0xa0A potato variety shall be regarded as being 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. The Member States shall revoke the measures taken to control Potato Wart Disease or to prevent it from spreading only if Synchytrium endobioticum is no longer found to be present. The Member States shall prohibit the holding of cultures of Synchytrium endobioticum. Member States may authorise derogations from the measures referred to in Articles 3, 4, 5 and 7 for scientific purposes, tests and selection work provided that such derogations do not prejudice the control of Potato Wart Disease and create no risk of the spread of this disease. Member States may adopt such additional or stricter provisions as may be required to control Potato Wart Disease or to prevent it from spreading; 01.xa0xa0xa0The Member States shall communicate to the Commission before 1 January each year a list of all the varieties of potato accepted by them for marketing and which they have found, by official investigation, to be resistant to Synchytrium endobioticum. They shall state the races to which the varieties are resistant.2.xa0xa0xa0The Commission shall ensure that a list of resistant varieties, based on the communications from the Member States, is published each year, if possible before 1 February. 1The Member State shall ensure that contamination by Synchytrium endobioticum and the resistance of potato varieties to this organism are determined by appropriate methods to which Member States raise no objection. 2Member States shall bring into force the measures necessary to comply with this Directive within two years following its notification and shall forthwith inform the Commission thereof. 3This Directive is addressed to the Member States.
