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.

Treat at any time when the brush is dormant and the bark is dry. Best results have been obtained with late winter to early spring applications.

In most cases, once Crossbow Herbicide has been applied, there is not enough of the active ingredient on the plant in order to harm an animal. There are pets that do have more of a sensitivity than others to certain products so if your pet is one of them, we would recommend keeping them out of the treated area.

The product label for Crossbow Herbicide only lists that it can be used in non crop areas and specifically states: Do not apply directly to, or otherwise permit it to come into direct contact with cotton, grapes, tobacco, vegetable crops, citrus, flowers, fruit or ornamental trees, or other desirable broadleaf plants and do not permit spray mists containing it to drift onto them.  Gordons Ornamec would be a better choice. This will eradicate grassy weeds but not clover. You may need to spot treat with a glyphosate product carefully like Killzall for the other weeds or manually remove them.
