What is the function of the Compendium?
This electronic compendium is intended to provide details of the status of all pesticide common names (not just those assigned by ISO), together with their systematic chemical names, molecular formulae, structural formulae and CAS Registry Numbers®. It is designed to function like a database, with several indexes that provide access to the data sheets.
ISO does not announce new common names when they are provisionally approved, and there can be a delay of several years before names are finally approved and published in an ISO Standard. The Compendium is updated each time that new ISO common names are provisionally approved, and whenever names are finally approved and published in a standard or an amendment. Probably the only printed document that includes all of the ISO common names is The Pesticide Manual, but this is published at intervals of 3–4 years.
If you are not familiar with pesticides and their chemistry, then you may find it helpful to read the basic introduction and to look up terms in the glossary.
This compendium is not intended to include trade names or code numbers; many trade names for current products can be found in The Pesticide Manual.
The Compendium includes:
1) Data sheets
- A data sheet for each of the 1280 substances for which common names have been approved by ISO, completely (1122 names), approved but not published (140 names) or provisionally (18 names), up to June 2021.
- Names that are marked as “published” have completed the approval process and have been published in an ISO Standard, addendum or amendment. There are 1122 names in this category.
- Names that are marked as “approved” have also completed the approval process but have not yet been published in an ISO Standard, addendum or amendment. There are 140 names in this category.
- Names that are marked as “provisionally approved” are waiting to be balloted for final approval prior to publication. It is extremely unusual for a name to be rejected after it has been provisionally approved, and so these names are widely used on product labels and in the literature.
- A data sheet for each of 269 substances for which common names have been approved by organizations other than ISO, and for which there is no corresponding ISO common name.
- A data sheet for each of 241 substances included in ISO 765:2016 Pesticides considered not to require common names.
- A data sheet for each of 80 other substances that are known by trivial names or short chemical names, and for which there is no ISO common name.
- A data sheet for each of 389 ester and salt derivatives of substances that have common names, and where the biological activity lies in the parent compound.
Each data sheet includes the status of the common name, its IUPAC and CAS systematic names, its CAS Registry Number®, its molecular formula, its activity (using terms from the Classified lists of pesticides), notes on alternative names and simple esters and salts, its structural formula (scaleable SVG images from ChemDoodle), and its InChI and InChIKey (generated from structures drawn in the free version of ChemSketch from Advanced Chemistry Development, Inc. (ACD/Labs)).
CAS Registry Number® is a Registered Trademark of the American Chemical Society.
The indexes of IUPAC systematic names, Chemical Abstracts systematic names, Registry Numbers, and molecular formulae contain entries for over 350 simple esters and salts, in addition to the entries for their parent compounds.
3) Pesticide classification
- Classified lists of pesticides, in which each major group of pesticides (e.g. herbicides) is subdivided into chemical classes (e.g. chloroacetanilide herbicides). As an aid to navigating the longer lists, there are summaries containing just the chemical classes and not the individual substances. There is also a list of the chemical classes.
The CAB Thesaurus and the NAL Agricultural Thesaurus use a simplified version of this classification.
How are pesticides named?
Technical Committee 81 of the International Organization for Standardization (ISO) has devised a system for naming pesticides, with the aim of ensuring that common names indicate similarities between related compounds, do not conflict with any other names, and are suitable for use in many languages. New common names for pest control chemicals are provisionally approved each year by the Committee, and are then used in the literature and on product labels. These names are equivalent to the generic names of pharmaceuticals.
