The new Global Resistance Management (GRM) Mode of Action App, released earlier this year by the Resistance Action Committees (IRAC, HRAC FRAC), has just been updated with additional features. The App combines the information on the Resistance Action Committee’s standalone Mode of Action Apps into one application for ease of access by the user. The individual IRAC, FRAC and HRAC Mode of Action Apps are still available and all applications can be downloaded from the Apple App and Google Play stores.
IRAC MoA Group 30 insecticides (GABA-gated chloride channel allosteric modulators) are a new class of insecticide chemistry with first registrations in agriculture made during 2018. They represent a valuable resource for the control of insect and mite pests in many agricultural and horticultural markets and therefore it is considered essential to develop IRM guidelines to maintain their effectiveness through sustainable use.
The general principles of resistance management apply to seed and soil treatments as with foliar applied insecticides, however there are some additional factors that should be considered. There are limited insecticide modes of action available for use either as soil or seed treatments, therefore, the judicious use of the available modes of action is essential for sustainable control of the insect pests targeted by these applications. The updated IRAC guidelines provide more information.
The Chewing Pest WG is a new group for IRAC combining the past Lepidoptera and Coleoptera WGs and complements the Sucking Pest WG. These two key groups sit within the IRAC Crop Protection Team along with the Nematode WG. The team held their first conference call on August 24th 2021, agreed membership and drafted some initial objectives. Further information can be found on the Chewing Pest WG homepage

This module is designed to introduce the basic concepts behind the development and management of insecticide resistance in agricultural and horticultural crops. The presentation is targeted to those that may be being exposed to the concept of insecticide resistance for the first time or simply wishing to refresh their knowledge. More detailed information on the factors which influence resistance development and its management will be provided in future modules produced by IRAC International.
The IRAC Nematode Working Group is the most recently established IRAC team. The initial objectives of the team were to investigate the resistance risk of nematicides and to develop a mode of action classification scheme similar to that available for insecticides and acaricides.
Both these objectives have now been completed with the publication of the Nematicide Resistance Risk Statement at the end of 2018 and more recently the release of the Nematicide MoA Classification and corresponding MoA poster in September 2019
CropLife formally confirmed the UPL membership of IRAC International on the 23rd August 2019. With the mergers and acquisitions of various crop protection companies, along with the joining of UPL, this brings the number of IRAC International company members to 11. Good representation across the industry enables IRAC to continue providing a global coordinated response to insect resistance management strategies.
The IRAC Mode of Action App in IOS and Android has been updated to include the latest changes to the MoA Classification (Ver. 9.3, June 2019). This incorporates some additional MoA Groups including bio-insecticides. The update also includes some additional features such as an active ingredient search and links to the latest IRAC News on the IRAC website.
