Cuba
Seed potatoes (16 July 2019)
Nematodes
A consignment test for potato cyst nematodes (Globodera rostochiensis and G. pallida) and Heterodera spp. is required before export (PCN testing for export applies).
Two samples will be taken, one will be analysed by the Cuban laboratories in Europe the other will accompany the consignment.
The potatoes will only be cleared for export when the initial soil sample is cleared. The maximum tolerance for Heterodera species is 1 viable cyst per 20 gramme of soil per 25 tonnes of tubers.
In addition tuber samples of 5 bags of 200 tubers for each 25 tonnes lot (or 1% of the sacks of each lot) will be taken. The samples will accompany the consignment.

The crops of seed potatoes destined for export to Cuba, may need to be visited by Cuban government inspectors before defoliation. If this inspection does not occur the results of the growing crop inspection will need to be supplied to the Cuban authorities at the same time as consignment samples are taken.
Tuber tolerances
Minimum tolerances for seed export apply, except for:
- Wet rot/Blackleg: 0%
- Frost damage: 0%
- Powdery scab (Spongospora subterranea): no more than 0.1% may have 12.5% - 25% surface area covered
- Common scab (Streptomyces spp): 1.5 (Dutch scale)
- Rhizoctonia: 10 % (light) (Dutch scale)
- Practically free of soil and other plant parts
