Diseases and pests considered in the certification process
The certification of seed potatoes is based on the general technical regulations and the additional technical regulation for growing, inspecting and certifying seeds laid down by the Ministry of Agriculture. These regulations include the European Directives on trading (66/403/EEC) and plant health (2000/29/EEC).
Regulations are laid down, in particular, for the propagation of the crops (establishments admitted to control, genealogical scheme, isolation, etc.), seed storage (storage conditions), scoring the crop (field standards) and the batch (batch standards). The main criteria for seed potato production are identity, variety purity and health status.
The health status of the seed potatoes is one of the major factors in certification and this has led to the creation of practical technical information files that are available on this site. These files enable you to be up-dated on the diseases and pests covered by the inspection and also on other pests which are not yet regulated.
Pests and diseases are classified as follows:
• May be tolerated: classification in the group of quality organisms;
• Must not be tolerated: this group contains organisms which lead to quarantine.
Inspections (see the "French seed potato standards" table) are carried out for each pest or disease at each stage of the genealogical scheme for the production of seed potatoes. However, other non-regulated pests and diseases may also be taken into account if, for example, they could damage the ability of the seed potatoes to sprout.
A practical guide to diseases, pests and disorders of the potato
Le guide pratique "Maladies, ravageurs et désordres de la pomme de terre" est destiné à une utilisation au champ.
Il offre une clé d'identification des maladies à partir des symptômes observés en comparaison avec des photos de ces symptômes. Pour chaque maladie, ravageur ou désordre physiologique, une fiche descriptive précise les agents responsables, les symptômes en végétation, les conditions de développement et les moyens de lutte.
Ce guide pratique est également édité en anglais et en espagnol.
