Crossbow Herbicide is labeled for the control of most kinds of unwanted trees. On page 5 of the label you can fine directions on how to use for conventional basal bark and stump applications. For larger or established trees, cutting the tree and making a stump application will be the best way to treat.
Crossbow should not harm established trees but may damage younger trees if applied directly to them. To avoid injury, do not apply directly on or within the drip line of smaller trees and avoid the foliage and any exposed roots of mature trees. It is best to carefully spot treat the target plants to avoid injury to your desirable trees.
Becuase the roots can spread out 50-80ft from the tree, it is advised to cut the stump as low to the ground as possible. Black Walnuts are know for resprouting, using a product with the active ingredient Glyphosate is going to be your best option. Using Roundup QuickPRO which has Diquat as 1 of the 2 ingredients works for a faster knockdown and aborbs throughout the root system better. Below is a step by step guide on how to ensure the saplings won't regerminate.
Step 1 - Space cuts around the trunk of a mature tree, using a hatchet. These cuts should go down at an angle, exposing some inner flesh of the trunk. Alternatively, cut a straight line around the trunk, removing the bark along the line. For saplings, there's no need to remove bark because the young bark is thin.

Crossbow Herbicide is a vegetation management product which means it is not very selective, it will kill almost anything. Although it will not harm a tree when used at recommended levels if it gets on the base of the tree, it will harm a tree if you spray Crossbow on the foliage. The required spray volume will increase substantially if the brush exceeds 5 feet in height. Brush over 8 feet tall is difficult to treat efficiently. Large brush or trees may be controlled better by basal or mechanical methods.
