Consultation on Florasulam and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2021-03

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of florasulam and associated end-use products for sale and use in Canada with additional risk mitigation measures.

Florasulam is a herbicide that has value in providing control or suppression of a wide spectrum of annual and perennial broadleaf weeds, including those hard-to-control weeds such as cleavers and wild buckwheat, in cereal crops, grass pastures, and summerfallow.

With respect to human health, potential risks from dietary and occupational exposure were shown to be acceptable when florasulam is used according to the proposed conditions of registration, which includes additional mitigation measures such as personal protective equipment and standard restricted-entry intervals.

The environmental risk assessment found potential risks associated with the use of florasulam, but were shown to be acceptable when used according to proposed conditions of registration, which includes new mitigation measures, such as precautionary statements, and spray buffer zones for the protection of terrestrial and aquatic habitats.

For a full list of products containing florasulam, please consult Appendix I in the PRVD or visit the Pesticide Label Search database.

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