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.”

Video: Spring weed control in winter wheat with Broadway® Star (pyroxsulam + florasulam)

#CortevaTalks brings you a short update with Cereal Herbicides Category Manager, Alister McRobbie, on how to get the most out of Broadway® Star.

Significant populations of grassweeds, including ryegrass and brome, can threaten winter wheat yields. Spring applications of a contact graminicide, such as Broadway Star from Corteva Agriscience, can clear problem weeds, allowing crops to grow away in the spring.

Broadway Star (pyroxsulam + florasulam) controls ryegrass, sterile brome, wild oats and a range of broad-leaved weeds such as cleavers. It can be applied to winter wheat up until GS32, but the earlier the application is made, the smaller the weed, and the greater the benefit to the crop. Weeds should be actively growing. A good rule of thumb is that if your grass needs cutting, conditions are right to apply Broadway Star.
