ISF recommends that companies worldwide use these codes in catalogues and other communication with customers.
One of the goals of the seed industry is the consistent use of terminology. To support this ISF proposes pest codes for pests affecting vegetable crops.
See latest update (November 2022): pest codes for vegetable crops
The pest codes of cereal crops are no longer updated; it is only informative.
The codes are reviewed at regular intervals to verify the correctness of the information provided and an updated version is posted online every year. As an aid to seed companies in major non-English speaking countries common names of diseases affecting vegetable crops in Dutch, French, Japanese and Spanish have also been listed.
Guidelines for Coding Pests of Vegetable and Cereal Crops
Every effort has been made to remain consistent with the terminology used by internationally recognized institutions such as the American Phytopathological Society (for fungi), the International Committee for the Taxonomy of Plant Pathogenic Bacteria (of the International Society of Plant Pathology (ISPP)) (for bacteria) and CAB International Bioscience (formerly the International Mycological Institute, IMI) (for fungi and bacteria), and the International Committee for Taxonomy of Viruses (ICTV) (for viruses). In case of any deviation, an explanatory note is provided.
Taxonomic changes to the Latin binomial may necessitate a change in the code. The following procedure has been established:
- List the old name and quote the new name between brackets, i.e. ‘old name’ (now ‘new name’)
- List the new name and quote the old name between brackets i.e. ‘new name’ (ex ‘old name’)
- Quote the new name only
The transition from one step to the next is three years to allow companies and their customers worldwide to become accustomed to the change. It also takes into consideration the fact that organisations such as ICTV meet only once in three years to evaluate proposed taxonomic changes. Companies may choose to use the new name and accompanying code in catalogues and other communication earlier if they wish.
A pest affecting more than one crop receives one code.
Forma specialis (plural formae speciales) abbreviated to f.sp. (plural ff.spp.) is a taxonomic group of races and biotypes within a pathogenic fungal species that can infect only plants within a specific host genus or species.” (Source: Agrios, 1997; Edel-Hermann & Lecomte, 2019; APS Illustrated Glossary of Plant Pathology, 2001)
