Health Canada is consulting Canadians on the proposal to continue some uses of abamectin and associated end-use products in Canada, provided new risk mitigation measures are put in place. The use of abamectin on greenhouse ornamentals grown for cut flowers is proposed for cancellation since occupational postapplication risks were not shown to be acceptable when used according to the current conditions of registration, or when additional mitigation is considered.

Abamectin is an acaracide/insecticide registered for use on a wide-range of outdoor field-grown fruit and vegetable crops, outdoor ornamentals, greenhouse vegetables and greenhouse ornamentals for the control or suppression of a variety of agricultural pests such as mites, sawflies, moths, thrips, leafminers, psyllids, aphids and certain beetles. It is also registered for commercial and domestic indoor and/or outdoor structural use to control cockroaches and ants.

To protect human health and the environment, the following risk-reduction measures are proposed:

Add personal protective equipment requirements for application of abamectin via handheld airblast/mistblowers
Limit the amount handled per day for application of abamectin via handheld airblast mistblowers
Impose restricted-entry intervals (REIs) of 1–11 days for onions, grapes and hops
Cancel the use of abamectin on greenhouse ornamentals grown for cut flowers as agronomically feasible REIs could not be established
Update label to meet current standards pertaining to personal protective equipment and best practice statements (spray drift)
Update commercial and domestic class structural end-use product labels to include a precautionary statement to protect domestic animals/pets
To protect aquatic organisms, maintain a vegetative filter strip and limit the maximum cumulative application rate.

For a full list of products containing abamectin, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.

For more information on the proposed decision open the “Proposed Re-evaluation Decision”.
