Mode of Action Team News
Following a first registration in Australia, afidopyropen from BASF has been added to the IRAC MoA Classification Scheme as Group 9D. Previously it was included in the Appendix awaiting registration. The product is intended for the control of green peach aphid (Myzus persicae), cabbage aphid (Brevicoryne brassicae), currant lettuce aphid (Nasonovia ribisnigri) and cotton/melon aphid (Aphis gossypii); and for the suppression of silverleaf whitefly in brassica vegetables, celery, cucurbits, fruiting and leafy vegetables (including brassica leafy vegetables), parsley, potato, sweet potato, ginger and cotton. The product is also intended for the control of aphids in ornamentals.
The initial objectives of the team will be to investigate the resistance risk of nematicides and to develop a mode of action classification scheme similar to that available for insecticides and acaricides. Information will be posted on the website under Nematode Team.
A video from CropLife International and the Insecticide Resistance Action Committee (IRAC) that explains the importance of mode of action as the basis for effective and sustainable resistance management to preserve the utility and diversity of available insecticides and acaricides. The video can be viewed in English or watch it in Spanish, Mandarin or Portuguese.
The MoA Classification has been updated by the IRAC MoA Team and the updates approved by the IRAC Executive. The latest version of the Classification Scheme can be downloaded from the IRAC website. The English version of the IRAC Chemical Structures Poster and the small IRAC MoA Booklet have also been update and can be downloaded from the website.
In this issue we focus on mode of action (MoA) and its importance in insecticide resistance management (IRM). We present a review paper on IRM and the IRAC MoA Classification and summarize the changes that have been made to the latest version of the classification scheme.

The popular IRAC Mode of Action Classification mini-booklet and the poster showing the chemical structures has been updated and reprinted. The previous printed editions related to earlier version of the classification scheme but these latest editions are based on the most recent classification version 7.3. In addition the format and layout has been improved and many of the chemical structures on the poster have been redrawn to standardise the nomenclature. Both the booklet and the poster can be downloaded from the website.
If you would like printed copies please contact your IRAC Member Company representative or Alan Porter, the IRAC Coordinator ([email protected]). You can also use the contact form link at the bottom of the website pages.
Information from Dupont on triflumezopyrim, their new mesoionic insecticide for control of rice hoppers, has been reviewed by the IRAC MoA WG and a classification to Group 4E agreed. The first registration for triflumezopyrim is expect in 2015 after which the active will be include in the IRAC MoA Classification Scheme. Meanwhile a new appendix will be added to the scheme to cover actives such as triflumezopyrim that have been classified but are pending registration.
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.
An easy to use database that allows you to identify all insecticides in any given mode of action group. The app allows the user to filter and search by either MoA group or insecticide and is free to download from the iTunes Apple Store or the Google Play Store. Suitable for use with tablets and phones.
