The Canadian Pest Management Regulatory Agency has approved the continued registration of the herbicide trifluralin, following a special review of the active ingredient.

Trifluralin, a pre-emergent soil herbicide used to control annual grasses and broadleaved weeds, is currently registered in Canada for use on ornamentals, shelterbelts, terrestrial food/feed crops, oil seed and fibre production crops. Currently there are four technical grade active ingredients, one manufacturing concentrate, twelve commercial and one domestic-class products containing trifluralin registered in Canada
