Emergency use approved for labelled weeds in carrots

The Pest Management Regulatory Agency (PMRA) recently announced the approval of an Emergency Use Registration (EUR) for Tough  600 EC herbicide for control of labelled weeds on carrots in numerous provinces in Canada. This EUR for Tough 600 EC herbicide on carrots can be used only in British Columbia, Saskatchewan, Manitoba, Ontario, Québec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador from May 1st, 2022, until December 31st, 2022.

Tough 600 EC herbicide was already labeled for management of weeds on a wide range of crops in Canada. This use will also be addressed as a future label expansion by an Agriculture and Agri-Food Canada – Pest Management Centre (AAFC-PMC) submission through the regional upgrade selected by the Maritime provinces at the 2022 AAFC-PMC ‘A’ priority setting workshop (pending favourable trial results and subsequent submission evaluation by PMRA).  This EUR request was initiated by participating provinces in response to significant expected shortages of a key weed management tool in the 2022 field season which Canadian carrot growers traditionally rely upon for post emergence weed control.

The following is provided as an abbreviated, general outline only. Users should be making weed management decisions within a robust integrated weed management program and should consult the complete emergency use label before using TOUGH® 600 EC Herbicide.
