Health Canada to approve ISK BioSciences' tiafenacil-based herbicide

Health Canada's Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is proposing registration for the sale and use of ISK BioSciences' Tergeo Technical Herbicide, Tiafenacil 70WG Herbicide and Tiafenacil 339SC Herbicide, containing the technical grade active ingredient tiafenacil, to control weeds in field corn, soybean, spring wheat, grapes, summerfallow and non-crop areas.

An evaluation of available scientific information found that, under the approved conditions of use, the health and environmental risks and the value of the pest control products are acceptable.

Tiafenacil is a non-selective, contact herbicide for weed management early in the season in certain crops, and throughout the season in grapes and non-crop areas.

Tiafenacil 70WG Herbicide and Tiafenacil 339SC Herbicide, containing tiafenacil, are conventional, non-selective, contact herbicides for the control or suppression of certain annual broadleaf weed species when applied in the early season in field corn, soybean and spring wheat, and throughout the season in grapes, summerfallow and non-crop areas.

Tiafenacil 70WG Herbicide and Tiafenacil 339SC Herbicide will serve as additional options for early season weed management and can be included as a component of integrated weed management programs that include tillage and other preplant, pre-emergent and/or postemergent herbicides for season-long weed management.
