Cimarron® Max Herbicide

DuPont™ Cimarron® MAX Herbicide provides postemergence control and suppression of key broadleaf weeds and brush in pastures and rangeland as well as selective weeding to aid in the maintenance of established grasses in the Conservation Reserve Program (CRP).

With contact, systemic and residual activity, a single application of Cimarron® MAX Herbicide is an effective option providing season-long control of a wide spectrum of annual and perennial broadleaf weeds including musk thistle, broom snakeweed and western ragweed plus suppression of mesquite, yucca and other brush species – without harming grasses.


Cimarron® MAX Herbicide gives ranchers the flexibility they need with more time to work around their schedule and the weather. Plus, there is no waiting period between application and the grazing of livestock.
