Seed potatoes (updated 16 July 2019)

Growing crop tolerances

Class tolerances apply. 

Tuber tolerances

Procedures on arrival

The Algerian authorities may strictly apply the rules on tuber size and number, and reject consignments that do not comply.

Laboratory tests

Routine laboratory and growing-on tests are carried out for viruses, applying the following tolerances:

  • For SE:          1% virus of which 0.5% PVY and PLRV

Wart disease

Wart disease (Synchytrium endobioticum) must never have been found in the field in which the potatoes were grown.
