IRAC mode of action classification – Status and updates to the global standard for insecticide MoA

The Insecticide Resistance Action Committee (IRAC) is a Specialist Technical Group of CropLife International that is focused on ensuring the long term efficacy of insect control products through effective resistance management. A key component is the Mode of Action (MoA) classification scheme, which serves as a basis for constructing appropriate Insecticide Resistance Management (IRM) strategies using a range of available insect control products. The MoA classification scheme is maintained by the recently formed IRAC MoA Working Group (WG). The IRAC MoA WG has recently revised the information in the MoA scheme. The revised MoA scheme, and its use in IRM will be discussed.
