Consultation on Clodinafop-propargyl and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2018-16

Notice to the reader:

This consultation is now closed.

Clodinafop-propargyl is a registered herbicide used in western Canada on spring and durum wheat. It provides effective control of wild oats, a major weed problem for wheat growers in western Canada.

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 the current use of clodinafop-propargyl, with proposed label updates to further protect health and the environment.

A full list of products containing clodinafop-propargyl can be found the Pesticide Label Search or Appendix I of PRVD2018-16.

No risks of concern to human health or the environment were identified for all uses of clodinafop-propargyl when it is used according to the proposed revised label directions. Those label revisions include plantback, preharvest and restricted-entry intervals as well as protective equipment to protect workers. Hazard and precautionary statements warn users to reduce spray and drift because of potential toxic effects on non-target organisms.

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