[F2(1A) In the case of tubers of Solanum tuberosum L., those surveys must include official testing of samples of seed and other potatoes in accordance with EPPO PM 7/59.
(1B) In the case of plants of Solanum tuberosum L., those surveys must be carried out according to appropriate methods and include appropriate official testing of samples.
