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.
