Will Ranger Pro kill buckthorn if applied to a cut stump? Must it be used undiluted?
We are not exactly sure of the dilution rate or how well Ranger Pro will work for the use you are describing. We would ask that you call the manufacturer since they are the experts on their own product and would know better than we would. We don't like to guess at an answer if we are not sure. The manufacturer is Monsanto Company and you can reach them at (314) 694-1000.
