Crownvetch is hard to control once it is established. Using a glyphosate such as Eraser 41% Weed Killer Herbicide or a triclopyr product is your best option to eradicate. It is recommended to apply per the product label rates on the cut stems and foliage. Follow-up treatment with herbicide is likely required to control any surviving stems or new seedlings. Be sure to avoid any contact with the desirable plants as Eraser is a non selective that will kill anything sprayed.
