1. Member States may authorise: (a) derogations from the measures referred to in Articles 4, 5 and 7 for scientific purposes, tests and selection work; by way of derogation from Article 4 (a), the growing on contaminated plots of varieties of potato which are resistant to pathotypes of Potato Cyst Eelworm found on the plots; by way of derogation from Article 4 (a), the growing on contaminated plots of potatoes other than seed potatoes, provided that it is ensured that such potatoes will be harvested before the cysts of Potato Cyst Eelworm mature; by way of derogation from Article 4 (a), the growing on contaminated plots of potatoes other than seed potatoes, where the ground has been disinfected by appropriate means. 2. The Member States shall ensure that the authorisations referred to in paragraph 1 are granted only where adequate controls guarantee that they do not prejudice the control of Potato Cyst Eelworm and create no risk of the spread of this pest. 3. A potato variety shall be regarded as being resistant to a particular pathotype of Potato Cyst Eelworm if, when that variety is grown, a natural and annual decrease in the population of that pathotype is found to occur.
