EPPO Plant Protection Thesaurus

Welcome to EPPO Plant Protection Thesaurus (EPPT)

The EPPO Plant Protection Thesaurus (EPPT) covers organisms important in agriculture and crop protection: crops, pests (including pathogens and weeds), natural enemies, and organisms used in ecotoxicological studies. EPPT includes the core data files of the Bayer codes which were previously available as a set of books or data files. This coding system is now managed by EPPO and Bayer codes can now be called EPPO codes.

For each organism EPPT provides:

  • preferred scientific name
  • EPPO (Bayer) code
  • other scientific names
  • common names in many languages
  • taxonomic relationships and other classifications
