Consultation on Fomesafen and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2018-15

Notice to the reader:

This consultation is now closed.

Fomesafen is a registered pesticide used by growers in Eastern Canada, Manitoba and British Columbia to control broadleaf weeds on a range of crops. A full list of products containing fomesafen, such as Flexstar or Reflex, can be found the Pesticide Label Search or Appendix I of PRVD2018-15.

Following a scheduled re-evaluation under the Re-evaluation Program, Health Canada’s Pest Management Regulatory Agency (PMRA) is consulting Canadians on the proposal to continue all uses of fomesafen on soybean, cucumber, strawberry, potato and some pulse crops, with proposed label updates to further protect health and the environment.

Proposed updates include the following, with more detail in the consultation document:

  • Label statements prohibiting application by air and in greenhouses
  • Required wait times before workers can re-enter treated areas
  • Updated buffer zone requirements
  • Addition of label statements on how to reduce the chance of runoff and drift
  • Label statements informing users of the potential for carryover of fomesafen from one season to the next

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