Corteva DuraCor® Herbicide

The most extensive pasture weed control available.

Featuring the first new active ingredient for pastures and rangeland in nearly 15 years, new DuraCor^® herbicide brings livestock producers and land managers the broadest-spectrum broadleaf weed control available for their grazing acres — one that’s loaded with benefits. 

DuraCor is powered by Rinskor™ active, a reduced risk herbicide that won the American Chemical Society’s Green Chemistry Challenge award. 

The American Chemical Society’s Green Chemistry award, given to companies or institutions that have developed a new process or product that helps protect public health and the environment, is the United States’ most prestigious award program for green chemistry innovations.

Benefits

DuraCor® herbicide provides extended control of 140+ weeds while maintaining grass safety. That allows nutritious grasses to thrive and opens the way for more productivity from every acre.

Control More Tough Weeds

DuraCor kills all the troublesome rangeland and pasture weeds — thistles, ragweeds, pigweed and others. But it also takes out especially tough-to-control broadleaves, including wild carrot, giant hogweed, wild parsnip, plantain, poison hemlock, the sunflower and aster families, and common caraway.

Extended Control

DuraCor stops the weeds that are up and growing while providing residual control of those that germinate later. That keeps pastures clean, forage grasses growing and cattle gaining.

Convenient Pasture Weed Control

Flexible application options, including broadcast by ground or by air; spot treatments; and the ability to mix with liquid fertilizer or impregnate on dry fertilizer in select states all make DuraCor the easy choice for pasture weed control. Low use rates, a low-odor formulation and no grazing restrictions add to the convenience factor.

Weed and Feed Efficiency

Unlike products that contain 2,4-D, DuraCor easily mixes with liquid UAN, even at near-freezing temperatures. In states where dry fertilizer impregnation is permitted, the low-use rate of DuraCor results in better flowing, less tacky prills.

Non-restricted

Unlike many other pasture management products, DuraCor is nonrestricted and does not contain 2,4-D or dicamba.
