| Mitochondrial complex II electron transport inhibitors. Succinate-coenzyme Q reductase | Fluopyram(1) | Pyridinyl-ethyl benzamides | FRAC 7(1) | 468 | 117 |
| All other modes of action | 8,526 | 638 | |||
| All insecticides | 31,611 | 1,355 | |||
| Area grown | 22,066 |
(1) Fluopyram is classed as a broad-spectrum fungicide but also has nematicide activity, hence the reason it has a FRAC group code rather than an IRAC code. Fluopyram was only used as a nematicide on veg crops in 2021
Note: Active substances have been grouped by their mode of action. Full details on insecticide and nematicide mode of action classification can be found on the Insecticide Resistance Action Committee (IRAC) webpage(8)
