New! The most extensive pasture weed control available. DuraCor

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™ herbicide controls broadleaf weeds and certain woody plants on rangeland, permanent grass pastures (including annual and perennial grasses grown for hay*), Conservation Reserve Program (CRP) acres, and wildlife management areas including seasonally dry flood plains, deltas, marshes, prairie potholes, or vernal pools in these sites.

And when it comes to hard control weeds – DuraCor outperforms GrazonNext HL – just check out the stats in this info sheet.
