The IRAC mode of action classification is considered as the definitive global authority on the target site of insecticides and crucial to this is the scientific integrity of the scheme. It is used globally to classify insecticides, as the basis for mode of action labelling, and is an essential tool for the development of IRM strategies involving multiple modes of action in a window-based approach.

The MoA Team, which is largely composed of technical experts, is charged with maintaining the scheme and its status, carrying out updates as required as well as developing educational resources such as posters to promote the correct use of the scheme. The team considers data to support new submissions for entries to the scheme and acts as an arbiter on questions of MOA.

Team Objectives

  • Continue to review and update the MOA scheme as required.
  • Develop new versions of the MOA Structure Poster as needed

Updated MoA Classification (Ver. 7.3)

The latest issue of the IRAC MoA Classification (ver. 7.3) has now been released and posted on the MoA Team page of the website. Changes include the renaming of a couple of groups/sub-groups (Group 9 is now “Modulators of Chordotonal Organs” and Subgroup 8D is now “Borates”) and the addition of flupyradifurone into a new Subgroup 4D, called Butenolides. The opportunity was also taken to improve some of the text and notes relating the the classification. Associated MoA resources (booklet and posters etc.) will be updated in due course.
