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.
Growing crop tolerances
Class tolerances apply.
Tuber tolerances
Minimum tolerances for seed export apply, except for:
- Maximum tuber size 60mm for 2023/4
- Frost damage: 0%
- Bacterial soft rot (Pectobacterium spp.): 0.05%
- Powdery scab (Spongospora subterranea): NIL
- Silver scurf (Helminthosporium solani): 0.1% (only dehydrated tubers and those with > 40% surface area affected are countable)
-
Peeled or green tubers: 2%
-
Soil: 0.2%

An official laboratory test for brown rot is required before export. The sampling rate is 200 tubers per 25 tonnes.
Other requirements
Sprouting: up to 2% of tubers may have sprouts of up to 2 mm in length.
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.
Documentation: a radiation certificate should be added to the phytosanitary certificate.

Additional declarations to be included on the reverse of the phytosanitary certificate for seed potatoes
- Potato wart disease (Synchytrium endobioticum) has never been found in Scotland on land used for seed potato production.
- Samples of soil from the land in which the potatoes were grown were drawn and tested by the Scottish Government prior to planting and revealed no trace of 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.
- Representative samples of tubers have been subjected to official testing for Brown rot (Ralstonia solanacearum) using appropriate European Community (EC) methods and have been found free, in these tests, from this harmful organism.
- Root knot nematodes (Meloidogyne chitwoodi and M. fallax), Potato tuber nematode (Ditylenchus destructor), Bacterial ring rot (Clavibacter michiganensis ssp. sepedonicus), Colorado beetle (Leptinotarsa decemlineata), Potato tuber moth (Phthorimaea (Gnorimoschema) operculella), Japanese beetle (Popillia japonica) and Potato spindle tuber viroid (PSTVd) are not known to exist in Scotland.
- Ditylenchus dipsaci was never recorded on potato crops in Scotland.
- Potato brown rot (caused by the bacterium Ralstonia solanacearum) has never been found in Scottish potatoes.
- The potatoes are the produce of crops inspected during the growing period by Inspectors of the Scottish Government and found to conform to the standards of freedom from virus diseases, Blackleg (Pectobacterium spp. (Erwinia atroseptica)) and Brown rot (Ralstonia solanacearum) required for classification in the Super Elite, Elite or A classes.
- The potatoes were visually inspected by the Scottish Government after harvest and found to be within the allowed limits for Powdery scab (Spongospora subterranea), Common scab (Streptomyces scabies), Black scurf (Rhizoctonia solani), Silver scurf (Helminthosporium solani), rots, damage, defects and soil.
Ware potatoes
Wart disease
Potato wart disease (Synchytrium endobioticum) must not be known to have occurred in the field where the potatoes were grown.
PCN
The field in which the potatoes were grown must have been tested for the presence of Potato Cyst Nematodes (Globodera rostochiensis and G. pallida) pre-planting or where this has not been carried out lot freedom from PCN using a consignment test must be demonstrated (PCN testing for export applies). There will be a charge for these tests.
Tuber tolerances
Minimum tolerances for ware export apply.
Additional declarations to be included on the reverse of the phytosanitary certificate for ware potatoes
- Potato wart disease (Synchytrium endobioticum) is not known to have occurred on the land used for the production of the potatoes.
- Samples of soil from the land on which these potatoes were grown were drawn and tested prior to planting by the official services and no trace was found of Potato cyst nematodes (Glodobera pallida and G. rostochiensis) or lot freedom from PCN has been demonstrated by consignment test.
- Root knot nematodes (Meloidogyne chitwoodii and M. fallax), Potato tuber nematode (Ditylenchus destructor), Bacterial ring rot (Clavibacter michiganensis ssp. sepedonicus), Potato brown rot (Ralstonia solanacearum), Colorado beetle (Leptinotarsa decemlineata), Potato tuber moth (Phthorimaea (Gnorimoschema) operculella), Japanese beetle (Popillia japonica) and Potato spindle tuber viroid (PSTV) are not known to exist in Scotland.
