NW Washington | Sometimes you can get an herbicide for less money if the clopyralid is mixed into a another chemical like the herbicide Curtail. This North Dakota SU bulletin says the patent is off of clopyralid now. Wonder why the stuff is still $500 per gallon? I think is it is banded in some places because it is so persistant.
