A plant health inspector must demarcate any contaminated plot and a safety zone around that plot which is large enough to ensure the protection of the surrounding area.

A plant health inspector must serve a notice under regulation 15(1) requiring any potato tubers or haulms which are present on the contaminated plot, or which come from the contaminated plot, to be treated in such a way that the Potato wart disease present on them is destroyed.

Where a plant health inspector is satisfied that any potato tubers or haulms are contaminated with Potato wart disease and the inspector cannot determine whether those tubers or haulms have been present on a contaminated plot, the inspector may serve a notice under regulation 15(1) which requires the whole batch containing the affected tubers or haulms to be treated in such a way that there is no risk of Potato wart disease spreading.
