EPPO Global Database

EPPO Reporting Service no. 04 - 2006 Num. article: 2006/089

New version of EPPO Plant Protection Thesaurus is now available

Since 1995, EPPO has managed the database formerly known as the Bayer Code System (© Bayer AG Germany). EPPO also produces an interface called the Plant Protection Thesaurus (EPPT) to consult this database. EPPT covers organisms important in agriculture and crop protection: crops, plant pests (including pathogens and weeds), hygiene pests, natural enemies, organisms used in ecotoxicological studies etc.
For each organism, it provides:
  • preferred scientific name
  • EPPO (Bayer) code
  • synonyms
  • common names in many languages
  • taxonomic relationships and other classifications
At present, about 28 000 species of plants are included (cultivated plants, wild plants and weeds), 19 200 species of animals (especially insects, mites and nematodes) and 4300 species of microorganisms. The data content of EPPT is constantly being improved, revised and extended. EPPT is provided on a CD-Rom and can be used on PCs running Windows 98, NT 4.0, 2000 or XP. EPPT is available at a price of 200 EUR. For more information please consult our web page:
