IRAC Mode of Action Classification Scheme (Classification Version 8.3 2017)

Only active constituents that are registered for fly control in feedlots, animal facilities, farm buildings or agricultural buildings and included in currently available products are listed in the table. Products containing these chemicals, which are all restricted to non-animal use, can be found on the PubCRIS database on the Australian Pesticides and Veterinary Medicines Authority (APVMA) website.

Handle and use insecticides according to label instructions. Information about Chemical use and Guidelines for safe and effective use of agricultural and veterinary chemicals is available from the Queensland Government Business Queensland website.

Rotation of chemical groups

Flies develop resistance when exposed to the same insecticide repeatedly. This makes the chemical ineffective as a fly control. To prevent flies building resistance, rotate the chemical groups.
