Control measures
- Use healthy seed potato tubers (cultivar resistance is not yet available).
- Maintain a lengthy crop rotation and make sure fields are properly drained to avoid water excess in soils.
- Keep harvest damage to a minimum.
- Ensure good skin set prior to harvest and avoid harvesting during hot and humid periods.
- Dry the tubers quickly and thoroughly after harvesting and prior to storage.
- Ensure good ventilation during storage to prevent condensation.
