Potato exports guide

Information on the conditions and phytosanitary requirements for the export of Scottish potatoes, where known by country.


Seed potatoes (updated 8 December 2020)

Potato cyst nematode (PCN)

 A consignment test for potato cyst nematode (Globodera rostochiensis and G. pallida) is required before export.

Growing crop tolerances 

Class tolerances apply. 

Tuber tolerances

Inspectors instructions UR/2007/01 apply. Minimum tolerances for seed export apply, except for:

  • Gangrene (Phoma foveata): NIL
  • Pink rot (Phytophthora erythroseptica): NIL
  • Skin spot (Polyscytalum pustulans): NIL
  • Powdery scab (Spongospora subterranea): (2% of incidence) please inspect to NIL tolerance - Please note that the authorities take a 50kg sample from each 150 tonnes (from each lot number). The inspectors calculate the incidence by assessing the number of powdery scab affected tubers in the total number of tubers in the sample. One pustule is countable - it is recommended to inspect to NIL tolerance.
  • Spraing (caused by PMTV): NIL
  • Common scab (Streptomyces scabies), Black scurf (Rhizoctonia solani), Silver scurf (Helminthosporium solani), as follows (max. tolerance by weight):
    Surface Area Common scab Black scurf Silver scurf All three combined
    > 10% 1.5% 1.5% 3% 5%
    5 - 10% 5% 5% 10% 10%
