Textual Amendments

F1 Annex 5 substituted (31.12.2020) by The Plant Health (Phytosanitary Conditions) (Amendment) (EU Exit) Regulations 2020 (S.I. 2020/1527), reg. 1(2), Sch. 5 (as amended by S.I. 2020/1631, regs. 1(2), 9(2)(a))

The competent authority, or the professional operator under the official supervision of the competent authority, must carry out checks and take any other action which is necessary or appropriate to ensure that the requirements specified in the following table in relation to the respective RNQPs and plants for planting are satisfied:

(1)RNQPs or symptoms caused by RNQPs	(2)Plants for planting (genus or species)	(3)Requirements
Blackleg (Dickeya Samson et al. spp. [1DICKG]; Pectobacterium Waldee emend. Hauben et al. spp. [1PECBG])	Solanum tuberosum L.	In the case of pre-basic seed potatoes, official inspections show that they derive from mother plants which are free from Dickeya Samson et al. spp. and Pectobacterium Waldee emend. Hauben et al. spp. In the case of all categories, the growing plants have been subjected to official field inspections by the competent authority.
Candidatus Liberibacter ‘solanacearum’ Liefting et al. [LIBEPS]	Solanum tuberosum L.	In the case of pre-basic seed potatoes, official inspections show that they derive from mother plants which are free from Candidatus Liberibacter ‘solanacearum’ Liefting et al. In the case of all categories: (a) the plants have been produced in areas known to be free from Candidatus Liberibacter ‘solanacearum’ Liefting et al., taking into account the possible presence of the vectors, or (b) no symptoms of Candidatus Liberibacter ‘solanacearum’ Liefting et al., have been seen during official inspections by the competent authority of growing plants at the site of production since the start of the last complete cycle of vegetation.
Mosaic symptoms caused by viruses and symptoms caused by Potato leaf roll virus	Solanum tuberosum L.	In the case of pre-basic seed potatoes, they derive from mother plants which are free from Potato virus A, Potato virus M, Potato virus S, Potato virus X, Potato virus Y and Potato leaf roll virus. Where methods of micro-propagation are used, compliance with this requirement must be established by official testing, or testing under official supervision, of the mother plant. Where methods of clonal selection are used, compliance with this requirement must be established by official testing, or testing under official supervision, of the clonal stock. In the case of all categories, the growing plants have been subjected to official inspection by the competent authority.
Meloidogyne fallax Karssen [MELGFA]	Solanum tuberosum L.	(a the tubers originate in an area in which Meloidogyne fallax Karssen is known not to occur, or (b where they originate in an area in which Meloidogyne fallax Karssen is known to occur: (i that the tubers originate from a place of production which has been found free from Meloidogyne fallax Karssen based on an annual survey of host crops, by visual inspection of host plants at appropriate times and by visual inspection both externally and by cutting of tubers after harvest from potato crops grown at the place of production, or (ii that after harvest the tubers have been randomly sampled and checked for the presence of symptoms after an appropriate method to induce symptoms or laboratory tested, as well as inspected visually, both externally and by cutting the tubers, at appropriate times, and no symptoms of Meloidogyne fallax Karssen have been found.
Potato spindle tuber viroid [PSTVD0]	Solanum tuberosum L.	In the case of clonal stock, official testing, or testing under official supervision, has shown that they derive from mother plants which are free from Potato spindle tuber viroid. In the case of pre-basic and basic seed potatoes, no symptoms of Potato spindle tuber viroid have been found, or for each lot, official post-harvest testing of tubers have been performed and those tubers have been found free from Potato spindle tuber viroid. In the case of certified seed potatoes, official visual inspection has shown that they are free from Potato spindle tuber viroid, and if any symptoms of the pest were seen, testing was carried out.
Symptoms of virus infection	Solanum tuberosum L.	During official inspection of the direct progeny, the number of symptomatic plants did not exceed the threshold specified in Part F of Annex 4.
Candidatus Liberibacter ‘solanacearum’ Liefting et al. [LIBEPS]	Solanum tuberosum L.	The competent authority has subjected the lots to official inspection and confirms that they do not exceed the threshold specified in Part F of Annex 4.
Ditylenchus destructor Thorne [DITYDE]	Solanum tuberosum L.	The competent authority has subjected the lots to official inspection and confirms that they do not exceed the threshold specified in Part F of Annex 4.
Black scurf affecting tubers over more than 10% of their surface, as caused by Thanatephorus cucumeris (A.B. Frank) Donk [RHIZSO]	Solanum tuberosum L.	The competent authority has subjected the lots to official inspection and confirms that they do not exceed the threshold specified in Part F of Annex 4.
Powdery scab affecting tubers over more than 10% of their surface as caused by Spongospora subterranea (Wallr.) Lagerh. [SPONSU].	Solanum tuberosum L.	The competent authority has subjected the lots to official inspection and confirms that they do not exceed the threshold specified in Part F of Annex 4.

In addition, the competent authority must carry out official inspections to ensure that the presence of the RNQPS on the growing plants specified in any entry of the table below do not exceed the thresholds in the corresponding entries of the table:

(1)RNQPs or symptoms caused by RNQPs	(2)Plants for planting (genus or species)	(3)Thresholds for the direct progeny of pre-basic seed potatoes		(4)Thresholds for the direct progeny of basic seed potatoes	(5)Thresholds for the direct progeny of certified seed potatoes
