An EPPO code, formerly known as a Bayer code, is an encoded identifier that is used by the European and Mediterranean Plant Protection Organization (EPPO), in a system designed to uniquely identify organisms – namely plants, pests and pathogens – that are important to agriculture and crop protection. EPPO codes are a core component of a database of names, both scientific and vernacular. Although originally started by the Bayer Corporation, the official list of codes is now maintained by EPPO.[1]

EPPO code database[edit]

All codes and their associated names are included in a database (EPPO Global Database). In total, there are over 68,500 species listed in the EPPO database, including:[2]

Plants are identified by a five-letter code, other organisms by a six-letter one. In many cases the codes are mnemonic abbreviations of the scientific name of the organism, derived from the first three or four letters of the genus and the first two letters of the species. For example, corn, or maize (Zea mays), was assigned the code "ZEAMA"; the code for potato late blight (Phytophthora infestans) is "PHYTIN". By providing a unique and constant code for each organism the system provides a shorthand method of recording species and 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.
