An EPPO code, formerly known as a Bayer code, is an

vernacular. Although originally started by the Bayer Corporation
, the official list of codes is now maintained by EPPO.

EPPO code database

All codes and their associated names are included in a database (EPPO Global Database). In total, there are over 93,500 species listed in the EPPO database, including:[1]

Plants are identified by a five-letter code, other organisms by a six-letter one. In many cases the codes are

Zea mays), was assigned the code "ZEAMA"; the code for potato late blight (Phytophthora infestans) is "PHYTIN". The unique and constant code for each organism provides a shorthand method of recording species. The EPPO code avoids many of the problems caused by revisions to scientific names and taxonomy which often result in different synonyms being in use for the same species. When the taxonomy changes, the EPPO code stays the same.[2] The EPPO system is used by governmental organizations, conservation agencies, and researchers.[3][4]
