Corteva launches Extinguish XL broadleaf herbicide for wheat and barley


Corteva Agriscience has expanded its cereal herbicide portfolio in Canada with the launch of Extinguish XL herbicide, a broadleaf herbicide for wheat and barley farmers in Western Canada’s black and grey soil zones.

Equipped with multiple modes of action, Extinguish XL herbicide is a pre-formulated, all-in-one application that delivers control of tough weeds such as cleavers, dandelion, round-leaved mallow, stork’s-bill and narrow leaved hawk’s beard across variable climatic conditions, the company says.

Extinguish XL herbicide can be applied from the 2-leaf stage to just before the emergence of the flag leaf. The company says this wide application window, combined with its effectiveness across a range of temperature and moisture conditions, makes Extinguish XL herbicide a flexible solution to control broadleaf weeds.

The herbicide is a combination of Group 4 and Group 2 actives to assist farmers with problem weeds, including Group 2 resistant cleavers, chickweed and volunteer canola.

The new herbicide will be available at select retail locations ahead of the 2024 growing season.
