Canada clears continued registrations for imazamox herbicides and d-phenothrin insecticides

The Canada's Pest Management Regulatory Agency (PMRA) is granting continued registration of products containing imazamox from BASF for sale and use in Canada, after a re-evaluation of imazamox. An evaluation of available scientific information found that products containing imazamox do not present unacceptable risks to human health or the environment when used according to the conditions of registration, which include amended label directions.

Imazamox is a selective post-emergence herbicide, used for the control of broadleaf and grassy weeds in crops with imidazlinone tolerance in the Prairie provinces, Peace River region of British Columbia and Eastern Canada. There are 15 products containing imazamox that are currently registered in Canada under the authority of the Pest Control Products Act, including 1 technical grade active ingredient and 11 commercial class end-use products and 3 manufacturing concentrates.

It is approved for use in several Clearfield crops, soybean peas, dry edible beans (tank mix only), fenugreek for seed and forage uses, seedling and established alfalfa grown for seed, and bird's foot trefoil for seed production.

Additionally, the agency is also granting continued registration of products containing d-phenothrin for sale and use in Canada, after a re-evaluation of d-phenothrin. An evaluation of available scientific information found that products containing d-phenothrin do not present unacceptable risks to human health or the environment when used according to the revised label directions.

d-Phenothrin is a synthetic pyrethroid insecticide used to control a broad range of arthropod pests on a wide variety of sites, including in and around structures as well as indoor and outdoor ornamental plants. This insecticide is also used for flea and tick control.

The agency has opened the public comments for 60 days until June 29, 2016.
