Control measures

As there is no effective chemical control against potato wart, which can remain infective in a soil for more than 20 years, preventive measures and strict inspections and surveys are essential:

• the use of healthy certified seed tubers;

• avoiding the introduction of soil or planting material from infected areas and careful examination of introduced potato tubers;

• the use of resistant cultivars, particularly in the case of potato cultivation in potentially infested areas.

In Europe, national lists of resistant cultivars are available.
