Insecticides

The classification scheme listed below is adapted from the Insecticide Action Committee Mode of Action Classification (IRAC) V5.2, September 2006.

1 Although sharing the same primary target site, it is possible that not all members of a single major mode of action (MoA) class have been shown to be cross-resistant . However, for the purposes of this classification system, it should be assumed that cross-resistance exists between compounds in any one sub-group.

Fungicides

This classification scheme is based on the Fungicide Resistance Action Committee (FRAC) List, 2006
