In a production site designated as infected pursuant to Article 5(5), point (a), all of the measures set out in points (1), (2) and (3) or all of the measures set out in points (4) and (5) shall be taken: (1) during the first three growing years following the year of the designation of infection, elimination of volunteer specified plants, and prohibition of planting of specified plants, including seeds, or of crops for which there is an identified risk of the specified pest spreading; (2) from the fourth year following the year of the designation of infection, following the fulfilment of the conditions of point (1) and on the condition that the production site has been found free from volunteer specified plants during official controls for at least the two consecutive growing years prior to planting, only production of tubers other than those intended for planting shall be allowed and the harvested tubers shall be tested in accordance with Annex I; (3) after the first production of tubers as referred to in point (2), and following an appropriate rotation cycle of at least two years if tubers for planting are to be grown, specified plants may be planted for production either of tubers for planting or other tuber production, and a survey shall be conducted as provided in Article 3; or (4) during the first four growing years following the year of the designation of infection, elimination of volunteer specified plants and maintenance of the production site in bare fallow or in permanent pasture with frequent close cutting or intensive grazing; (5) from the fifth year following the year of the designation of infection, and on the condition that point (1) has been fulfilled and that the production site has been found free from volunteer specified plants during official controls for at least the two consecutive growing years prior to planting, production of tubers for planting and of other tubers shall be allowed, and the harvested tubers shall be tested in accordance with Annex I. 4.1.2. In all other production sites of the infected place of production, and under the condition that, for each growing year, the competent authority has established that the risk of volunteer specified plants has been eliminated and that testing of the harvested specified plants has been conducted in each production site of the specified plants in accordance with Annex I, the following measures shall apply: (1) in the growing year following that of the designation of infection either no specified plants, including seeds, shall be planted, or certified tubers for planting may be planted for production of tubers other than those for planting only; (2) in the second growing year following that of the designation of infection, only certified tubers for planting or tubers for planting officially tested for the absence of the specified pest and grown under official control on places of production other than those referred to in point 4 shall be planted for production either of tubers for planting or of other tubers; (3) for at least the third growing year following that of the designation of infection, only certified tubers for planting or tubers for planting grown under official control from certified tubers for planting shall be planted for production either of tubers for planting or of other tubers; (4) in each of the growing years referred to in points (1), (2) and (3), measures shall be taken to eliminate volunteer specified plants if present, and in each production site of the specified plants, harvested specified plants shall be tested as referred to in Annex I. 4.1.3. Immediately following the designation of infection pursuant to Article 5(5), and after the first subsequent growing year, all machinery and storage facilities on the place of production and involved in the specified plant production shall be cleaned and disinfected as appropriate using appropriate methods, as specified in point 3. 4.1.4. In a unit of protected crop production designated as infected pursuant to Article 5, point 5(a), where complete replacement of the growing medium is possible: (1) no specified plants, including seeds, shall be planted unless the following conditions are fulfilled: (a) elimination of the specified pest, (b) removal of all host plant material, (c) complete change in growing medium and cleaning and disinfection of the production unit, and of all equipment, (d) approval for specified plant production by the competent authorities; (2) specified plant production shall be from certified tubers for planting, or from mini-tubers or micro-plants derived from tested sources; 4.2. Within the demarcated area, in addition to the measures detailed under point 4.1, Member States shall take the following measures: (1) immediately following the designation of infection, they shall ensure that all machinery and storage facilities on such places of production and involved with the specified plant production are cleaned and disinfected, as appropriate, and using appropriate methods, as specified in point 3; (2) immediately, and for at least three growing years following the designation of infection: (a) they shall ensure that their competent authorities supervise the premises where tubers are growing, stored or handled as well as places of production which operate specified plant machinery under contract; (b) they shall require the planting of only certified tubers for planting or tubers for planting grown under official control for all specified plant crops within that zone, and testing after harvest of tubers for planting crops grown in places of production designated as probably infected pursuant to Article 5(5), point (b); (c) they shall require the separate handling of stocks of harvested tubers for planting from the stocks of other tubers on all places of production within the demarcated area, or a system of cleaning and disinfection to be carried out between the handling of tubers stocks; (d) they shall conduct the annual survey as provided for in Article 3(1); (3) they shall establish a programme, where appropriate, for the replacement of all stocks of tubers for planting over an appropriate period of time.
