Consultation on Triforine and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2019-02

Triforine is a fungicide registered for use on apples, highbush and lowbush blueberries, cranberries (in British Columbia only), Saskatoon berries, some stone fruits (cherries, peaches, plums and prunes), outdoor ornamentals and roses. It is applied by field sprayers, airblast sprayers and chemigation (cranberries only). A full list of products containing triforine can be found in the Pesticide Label Search database or Appendix I of this PRVD.

Following a re-evaluation of triforine, Health Canada’s Pest Management Regulatory Agency (PMRA) is consulting Canadians on the proposal to continue all uses of this active ingredient. Risks to human health and the environment were found to be acceptable when triforine is used according to the proposed revised label directions, with the addition of the following proposed risk mitigation measures:

• updated pre-harvest intervals, statements for personal protective equipment, and restricted-entry intervals to protect workers
• a statement to promote best practices to protect bystanders from spray drift
• spray buffer zones to protect non-target habitats
• an updated hazard statement on potential leaching into groundwater

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