Certification systems

Meeting requirements for certification is challenging. History showed that certification systems for clean stock programs are developed after a major outbreak of a hard to control disease. Examples of these clean stock programs are evident throughout all crops.

  • GSPP (Good Seed and Plant Practices) due to an outbreak of Clavibacter michiganensis michiganensis in tomato.
  • Naktuinbouw Elite for ornamental products because of the virus issues in Petunia
  • Geranium-Ralstonia program to eradicate Ralstonia solanacearum race 3 biovar 2
  • Softfruit certification

All of these programs rely on start clean, stay clean principles.
