Seed potatoes (updated 16 July 2019)

Potato cyst nematode (PCN)

A consignment test for potato cyst nematode (Globodera rostochiensis and G. pallida) is required before export (PCN testing for export applies). SASA will charge for this test. The PCN consignment test certificate with an additional letter (see Inspector's instructions ID/2007/01) should accompany the Phytosanitary Certificate. 

Growing crop tolerances

Class tolerances apply. 

Tuber tolerances

Inspector's instructions ID/2007/01 apply. Minimum tolerances for seed export apply, except for:

  • Violet root rot (Helicobasidium brebissonii): NIL
  • Watery wound rot (Pythium ultimum): NIL
  • Black leg/Soft rot (Pectobacterium spp . & Dickeya spp .): NIL
  • Fusarium wilt & rot (Fusarium avenaceum): NIL
  • White mould (Sclerotinia sclerotiorum) : NIL
  • Powdery scab (Spongospora subterranea ): NIL
  • Skin spot (Polyscytalum pustulans): NIL
  • Silver scurf (Helminthosporium solani): NIL
  • Spraing (caused by Potato mop top virus): NIL

A random sample of 200 tubers per crop should be drawn by the inspector and kept on the farm for a possible post harvest test for ring rot until the consignment is released by the Indonesian authorities. 

Other requirements

Import permit: required.

Packaging: If wood packaging is used (e.g. boxes, pallets), this should be treated and certified. Wood material should comply with International Standards for Phytosanitary Measures (ISPM 15) on wood packaging materials.

Laboratory tests

The Indonesian Agricultural Quarantine Agency is known to carry out laboratory tests for latent infection by most of the above pathogens to a strict NIL tolerance. Consignments found to be infected are likely to be destroyed even if no visible symptoms are present. Exporters are advised not to send lots to Indonesia without arranging pre-export tests and clearance with the Indonesian Agricultural Quarantine Agency.

Additional declarations to be included on the reverse of phytosanitary certificate for seed potatoes

  1. False root knot nematode (Nacobbus aberrans), Northern root knot nematode (Meloidogyne hapla), Citrophilus mealybug (Pseudococcus calceolariae), Septoria potato leaf spot (Septoria lycopersici var. malagutti) and Bacterial grapevine blight (Pantoea agglomerans) are not known to exist in Scotland.
  2. Samples of soil from the land in which the potatoes were grown were drawn and tested prior to planting and were found to be free from Potato cyst nematodes (Globodera rostochiensis and G. pallida). In addition, the lots to be loaded were identified and samples of soil obtained from each lot making up the cargo were tested for Potato cyst nematodes. None of the samples from the lots revealed the presence of viable cysts of Potato cyst nematodes.
  3. Potato wart disease (Synchytrium endobioticum) is not known to have occurred on the land where the seed potatoes were grown.
  4. Potato tuber nematode (Ditylenchus destructor), Seed potato maggot ( Delia platura), European corn borer (Ostrinia nubilalis), Gummy stem blight ( Didymella bryoniae), Tomato foot rot (Phytophthora cryptogea), Dematophora root rot (Rosellinia necatrix), Alfalfa mosaic alfamovirus, Tobacco streak ilarvirus and Tomato mite (Aculops lycopersici) have never been recorded in commercial stocks of potatoes grown in Scotland.
  5. Stem nematode (Ditylenchus dipsaci) has not been recorded in Scottish potatoes for more than 25 years.
  6. Dickeya spp. (Erwinia chrysanthemi) have never been found in Scottish seed potatoes.
  7. At the time of visual inspection of the tubers there were no visible signs of Violet root rot (Helicobasidium brebissonii), Silver scurf (Helminthosporium solani), Skin spot (Polyscytalum pustulans), Powdery scab ( Spongospora subterranea), Blackleg ( Pectobacterium cartovorum, P. atrosepticum ), Fusarium rot (Giberella avenaceae), Watery wound rot  Pythium ultimum), White mould (Sclerotinia sclerotiorum), Lesion nematodes (Pratylenchus spp.) and Potato mop-top pomovirus.
  8. The tubers are practically free from soil, plant debris and other dirt.

Ware potatoes

Tuber tolerances
