I have acres of woods being taken over by barberry. I last sprayed with Cleanout but some shoots are returning. I need a real killing spray.
Unfortunately we do not carry any products labeled to treat Japanese Barberry. However, after doing some research on a couple university websites, we have found 2 active ingredients that have been known to kill Japanese Barberry. Cutting the stump and applying products with the Active Ingredients, Glyphosate or Triclopyr has been shown to have great results for killing Japanese Barberry. Crossbow does contain the active ingrdient Triclopyr. We recommend contacting your local extension office to get a confirmation that this would give you the results you are looking for.
