Good farm hygiene (washing and disinfection of all facilities and destruction of waste, etc.).
Harvest within three to four weeks after haulm destruction when tuber skin is mature but not too late to favour disease development.
Check that harvesting, grading and storage equipment is well adjusted in order to limit or avoid any wounds.
Eliminate any tubers carrying rot.
Thoroughly dry newly harvested tubers to allow rapid healing of the wounds.
For seed potato production, chemical treatment may be applied to cleaned tubers shortly after harvesting. In some areas, a mixture of two fungicides, thiabendazole and imazalil, is recommended as many isolates of F. sambucinum are resistant to thiabendazole. However, the latter is effective on other fungi and on susceptible isolates of F. sambucinum.
