The CIPAC code number system is a simple approach for an unambiguous coding of active ingredients and variants used in the area/field of pesticides. For more details see the document "What are CIPAC Code Numbers".

The compounds are easily identified and searched by these codes, also used by many authorities such as the EU, FAO and WHO. You find the CIPAC Code also in the Cumulative Index covering the content of most Handbooks. Please find below a table containing at present more than 700 compounds. If you want to have a new active ingredient a CIPAC Code allocated, proceed as follows.

• Propose an ISO common name for the new compound.

• Contact Bruno Patrian and ask for the allocation of a CIPAC code for the compound.
