Yafe Seeds Productions – GSPP


Good Seed and Plant Practices (GSPP) is an international, transparent business chain system. The purpose of Good Seed and Plant Practices (GSPP) is to prevent tomato seed and plant lots from being infected by Clavibacter michiganensis subsp. michiganensis (Cmm).

GSPP ensures that the production site’s quality management system, work methods and information supply comply with the GSPP standard. Companies and their production sites are checked periodically. Verification by audit organizations ensures availability of healthy seeds and plants as well as reliable quality information per production site, per entity or per lot/batch.

Principles of the system:

  • isolation of the seed and seedling production location from the environment
  • prevention of infection by managing the risk factors
  • constant monitoring during the growing season of both seeds and young plants
  • check before delivery: all seed lots must be tested by seed tests approved by GSPP
  • independent audits

The GSPP standard is based on the state-of-the-art knowledge and will be evaluated yearly. Experts from the industry and research institutes are consulted to assure that the GSPP standard is up to date.
