The Insecticide Resistance Action Group (IRAG)

The AHDB-supported Resistance Action Groups (RAGs) are informal, UK-based groups consisting of experts from the Crop Protection Association (CPA) member companies, other representatives from the agrochemical industry, a range of independent organisations, including public-sector research institutes, and the Chemicals Regulation Directorate (CRD).The groups are completely independent of AHDB and work to produce guidance on pesticide resistance issues. As part of its support to the resistance action groups, AHDB publishes IRAG guidance (last updated September 2018).

Aphid sampling protocol

Help us safeguard the efficacy of insecticides

As part of a UK aphid-monitoring programme, Rothamsted Research needs aphid samples, especially those that unexpectedly survive treatment with insecticides. Although any aphid species can be submitted, the researchers focus on some species/situations more than others to reflect samples received and the need to detect new resistance issues emerging in the UK aphid population.

New insights into insecticide resistance

New research raises questions whether insecticide resistance management guidelines should be revised. CPM finds out about current resistance threats and how these may be better managed in the future.
