Canada approves herbicides atrazine and trifluralin in special review

The Canadian Pest Management Regulatory Agency (PMRA) has proposed the continued registration of the herbicides atrazine and trifluralin , following a special review of two active ingredients.

Atrazine is a broad-spectrum triazine herbicide. It is currently registered for use in corn (maximum rate: 1.5 kg a.i./year; applied 1-2 times per year) and in sorghum (Eastern Canada only; maximum rate: 1.0 kg a.i./ha applied once per year). It is applied using ground equipment.

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.
