Consultation on Flucarbazone (present as flucarbazone-sodium) and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2022-02

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of flucarbazone (present as flucarbazone-sodium) and all associated end-use products registered for sale and use in Canada, provided new risk mitigation measures are put in place.

Flucarbazone has value as an important weed management tool for Western Canadian wheat growers. Flucarbazone is a selective herbicide used on wheat (spring, durum and winter) in Alberta, Manitoba, Saskatchewan, and Peace River region of British Columbia. It is used to control certain annual grasses and broadleaf weeds.

To protect workers during mixing, loading and applying and postapplication exposure, proposed risk-reduction measures include protective clothing and personal protective equipment, and a standard restricted-entry interval of 12 hours. To protect bystanders from agriculture application exposure, a best practice statement to reduce drift is proposed. To protect the environment a precautionary label statement indicating leaching is proposed for product labels, as well as terrestrial and freshwater aquatic buffer zones to mitigate risk from drift.

For a full list of products containing flucarbazone 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".
