Consultation on Ethephon and Its Associated End-use Products, Proposed Re evaluation Decision PRVD2018-01

This consultation is now closed.

Ethephon is a registered pesticide used only by agricultural workers. Ethephon releases ethylene gas, a natural plant hormone, to promote additional branching and flowering on greenhouse ornamentals. Ethephon is also applied as a broadcast foliar spray with ground, aerial, or backpack sprayer equipment and is used in a variety of crops including cereals, apples, sweet and sour cherries, blueberries, field tomatoes and tobacco. Ethephon product names include Base250, Ethrel, Cerone, Florel and Proxy (find full label names and labels for all registered products in the pesticide label search database.)

Following a scheduled re-evaluation under the Re-evaluation Program, Health Canada’s Pest Management Regulatory Agency (PMRA) is consulting Canadians on proposed changes to the way ethephon can be used, to further protect health and the environment.

Due to health concerns, proposed changes include the following, with more described in the consultation document itself:

  • Cancellation of uses on apple trees when fruit are present
  • Additional required protective clothing and equipment during application
  • Longer required wait times before workers can re-enter certain treated areas

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