regulations 2(1), 16(1)(e) and 20(3)
1.—(1) For the purposes of these Regulations—
(a)Table 1 applies—
(i)to seed potatoes classified under these Regulations as being of the class Pre-basic TC; and
(ii)to pre-basic seed potatoes produced outside Northern Ireland which are approved by the Department as being equivalent to that class;
(b)Table 2 applies—
(i)to seed potatoes classified under these Regulations as being of the class Pre-basic 1, Pre-basic 2, Pre-basic 3 or Pre-basic 4; and
(ii)to pre-basic seed potatoes produced outside Northern Ireland which are approved by the Department as being equivalent to these classes;
(c)Table 3 applies to basic seed potatoes, conservation varieties and equivalent, and test and trial seed potatoes, produced in Northern Ireland or any other part of the United Kingdom which are approved by the Department as being equivalent to either of these classes; and
(d)Table 4 applies in the case of basic seed potatoes produced outside the United Kingdom.
(2) Subject to paragraph (3), any tolerance in a Column of any of the Tables in this Schedule expressed as a percentage is a reference to the proportion which the weight of potatoes affected by the disease, pest, damage or defect bears to the total weight of the sample taken in accordance with regulation 21(3) and Schedule 8, expressed as a percentage.
(3) In the case of dirt or other extraneous matter, any tolerance in a Column of any the Tables in this Schedule expressed as a percentage is a reference to the proportion which the weight of such matter bears to the total weight of the sample taken in accordance with regulation 21(3) and Schedule 8, expressed as a percentage.
2. The individual tolerances set out in the entry in Column 2 of Table 1, 2, 3 or, as the case may be, 4 corresponding to the disease, pest, damage or defect set out in Column 1 of these Tables is specified in the case of seed potatoes to which the Table applies in relation to the disease, pest, damage or defect to which the entry corresponds.
3. The group tolerances set out in the entry in Column 3 of Table 2, 3, or, as the case may be, 4 corresponding to the diseases, pests, damage, or defects within Group 2 or 3 set out in Column 1 of those Tables is specified in the case of seed potatoes to which the Table applies in relation to the Group to which the entry corresponds.
4. The collective group tolerances set out in the entry in Column 4 of Table 1, 2, 3, or, as the case may be, 4 corresponding to the diseases, pests, damage or defects within Group 2, 3 and 4 set out in Column 1 of those Tables is specified in the case of seed potatoes to which the Table applies in relation to those Groups.
5.—(1) This paragraph applies, for the purposes of these Regulations, to seed potatoes to which Table 2, 3, or 4 applies.
(2) Subject to paragraph (3), an authorised officer may deem a potato in any sample of seed potatoes to which this paragraph applies not to be affected by a disease in Group 3, set out in Column 1 of the Table applicable to a potato of that class when, in the officer’s opinion—
(a)the surface area of the potato affected by the disease is less than the percentage surface area in the entry corresponding to the disease in Column 5 of the Table; and
(b)the potato has at least two eyes at the rose end wholly unaffected by the disease.
(3) Paragraph (2) shall not apply when the disease Powdery Scab (Spongosporasubterranea (Wallr.) Lagerh) takes its cankerous form.
