Consultation on foramsulfuron and its associated end-use products, Proposed Re-evaluation Decision PRVD2024-04

Current status: Open

Opened on 28 March 2024 and will close for consultation on 26 June 2024

Health Canada is consulting Canadians on the proposal to continue registration of products containing foramsulfuron for sale and use in Canada, with proposed label updates.

Foramsulfuron is a selective sulfonylurea herbicide used to control post-emergence broadleaf weeds in field corn (Eastern Canada and Manitoba) and lowbush blueberry (Eastern Canada only) sites. It is applied once per season by field sprayer and may be applied with tank-mix to enhance weed control efficacy.

With respect to human health, dietary, occupational, and bystander risks were shown to be acceptable when foramsulfuron is used according to proposed conditions of registration, which include label amendments to meet current labelling standards such as updates to personal protective equipment for mixers, loaders and applicators, and standard restricted-entry intervals.

The environmental risk assessment found that risks to the environment (terrestrial and aquatic) associated with the use of foramsulfuron were shown to be acceptable when used according to proposed conditions of registration, which include precautionary statements, and spray buffer zones for the protection of terrestrial and aquatic habitats.

For a full list of products containing foramsulfuron, 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".
