IRAC promotes the use of a mode of action classification of insecticides as the basis for effective and sustainable insecticide resistance management. Insecticides are allocated to specific groups based on their target site. The use of sequences or alternations of insecticides with different modes of action reduces selection pressure on individual target sites. This prevents, delays or reverses resistance and helps maintain product diversity and efficacy. IRAC believes that improved education on Mode of Action is needed and is maintaining this scheme on their website, www.plantprotection.org/irac . IRAC is working with EPA and others to increase working knowledge at the grower level on the importance of mode of action recognition.
