Official surveys and testingS

This section has no associated Policy Notes

38.—(1) The Scottish Ministers must ensure that annual systematic official surveys are carried out to identify the presence of R. solanacearum on specified plant material originating in Scotland F1....

[F2(1A) Those surveys must be based on a risk assessment to identify other possible sources of contamination threatening the production of susceptible material and include targeted official surveys in production areas, based on the relevant risk assessment, to identify the presence of R. solanacearum on—

(a)relevant material, other than susceptible material,

(b)surface water which is used for irrigation or spraying of susceptible material, and

(c)liquid waste discharged from industrial processing or packaging premises handling susceptible material.

(1B) Those surveys must also be based on the biology of R.solanacearum and the relevant production systems and must include—

(a)in the case of susceptible material comprising plants of Solanum tuberosum L., visual inspection of the growing crop at appropriate times, or the sampling of both seed and other potatoes in the growing season or in store, which must include official visual inspection by cutting of tubers,

(b)in the case of seed potatoes and, where appropriate, other potatoes, official testing of samples using the method set out in EPPO PM 7/21,

(c)in the case of susceptible material comprising plants of Solanum lycopersicum L., visual inspection at appropriate times of at least the growing crop of plants intended for replanting for professional use,

(d)for host plants, other than susceptible material, and for water including liquid waste, official testing.

(1C) The collection of samples for the purposes of sub-paragraph (1B) must be based on sound scientific and statistical principles and the biology of R.solanacearum and take into account relevant potato production systems of susceptible material and other host plants of R.solanacearum.]

(2) Where the presence of R. solanacearum is suspected, the Scottish Ministers must ensure that—

(a)official testing is carried out to confirm or refute its presence—

(i)in the case of specified plant material, using the method set out in [F3EPPO PM 7/21],

(ii)in any other case, using any officially approved method,

(b)pending the confirmation or refutation of its presence, where suspect diagnostic visual symptoms of R. solanacearum have been seen and a positive result in a rapid screening test has been obtained or a positive result in the screening tests [F4referred to in EPPO PM 7/21] has been obtained—

(i)the movement of all plants and tubers from all crops, lots or consignments from which the samples have been taken, other than those which are under official control, is prohibited, except where it has been established that there is no identifiable risk of R. solanacearum spreading,

(ii)steps are taken to trace the origin of the suspected occurrence, and

(iii)additional appropriate precautionary measures based on the level of estimated risk are taken to prevent any spread of R. solanacearum.

(3) A notice under regulation 15 may contain measures for the purposes of sub-paragraph (2)(b)(i) to (iii).
