5.—(1) This paragraph applies, for the purposes of regulation 16(1) and (3), to seed potatoes to which Table II, III (a), (b) or (c) or IV applies.
(2) Subject to sub-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 III, specified in column 1 of the Table in relation to a potato of that grade 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) Sub-paragraph (2) does not apply when the disease Powdery Scab (Spongospora subterranea (Wallr.) Lagerh) takes its cankerous form.
