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 demarcated areas and involved with specified plant production are cleaned and disinfected, as appropriate, using appropriate methods, as specified in point 3. (2) Immediately, and for at least three growing years following the designation of infection: (a) in cases where the demarcated area has been determined pursuant to Article 5(2), point (b): (i) they shall ensure that their competent authorities supervise the premises where specified plants are grown, stored or handled, as well as of places of production which operate machinery for specified plant production under contract; (ii) they shall require the planting of only certified tubers for planting or tubers intended to be planted on the same place of production grown under official control for all potato crops within that area, and testing after harvest of tubers for planting grown in places of production determined as probably infected pursuant to Article 5(2), point (d)(ii); (iii) they shall require the separate handling of harvested tubers for planting stocks from the stocks of other tubers on all places of production within the demarcated area, or a system of cleaning and, where appropriate, disinfection to be carried out between the handling of stocks of tubers for planting and that of other tubers; (iv) require the planting of only tomato plants grown from seeds which meet the requirements of Implementing Regulation (EU) 2019/2072 or, if vegetatively propagated, from tomato plants produced from such seeds and grown under official control, for all tomato crops within that demarcated area; (v) they shall conduct the survey as provided for in Article 3(1); (b) in cases where surface water has been designated as infected pursuant to Article 5(4), third subparagraph, point (a), or included in the elements for the possible spread of the specified pest in accordance with point 2 of Annex IV: (i) they shall conduct the annual survey at appropriate times, including sampling of surface water and where appropriate, of wild solanaceous host plants in the relevant water sources and they shall ensure that samples are subject to tests referred to in Annex I; (ii) they shall introduce official controls on irrigation and spraying programmes, including a ban on the use of the water designated as infected for the irrigation and spraying of specified plants, and, where appropriate, other cultivated solanaceous host plants in order to prevent the spread of the specified pest. That ban may be reviewed on the basis of the results obtained from intensive sampling and testing of the surface water, at appropriate times, to provide a high level of confidence that the specified pest is no longer present. The use of water subject to a ban may be permitted in greenhouses, under official control, for irrigation and spraying of tomato plants and other host plants intended for final consumption and processing, provided that the water is disinfected by using appropriate methods. In that case, the competent authorities may revoke the designation of water as infected by the specified pest; (iii) in cases where liquid waste discharges are infected, they shall introduce official controls on the disposal of solid or liquid waste discharges from industrial processing or packaging stations handling specified plants of the places of production. (3) They shall establish a programme, where appropriate, for the replacement of all stocks of tubers for planting over an appropriate period of time.
