New Corteva herbicide WideMatch receives US EPA registration

By Diego Flammini

U.S. wheat, durum, barley and triticale farmers will have another tool available to help them control weeds for the 2021 growing season.

The Environmental Protection Agency (EPA) granted a federal registration for WideARmatch, a new crop protection product from Corteva Agriscience.

Individual states would still have to authorize the use of the herbicide.

The herbicide represents the next generation of the company’s WideMatch herbicide.

WideARmatch has two unique sites of action, includes more fluroxypyr and introduces Arylex into the equation. Altogether, this will help preserve the Weed Science Society of America’s Group 4 mode of action.

Farmers can apply the product from the two-leaf growth stage to flag-leaf emergence. Applying the herbicide when the seedlings are less than four-inches tall will give best results, Corteva says.

The herbicide is labeled to help farmers control 66 broadleaf weeds including Canada thistle, marestail, dandelion and kochia.

Corteva originally submitted the herbicide to the EPA in February.

“WideARmatch will give wheat growers a new option, extending the spectrum of broadleaf control in an all-in-one low-use-rate premix formulation,” Brooklynne Dalton, cereals herbicide product manager at Corteva, said at the time. “This low use rate equates to less trips across the field, saving farmers time and money.”
