Q

Will this product or another Crossbow product kill my Mulberry tree?

A

Crossbow is a vegetation management product which means it is not very selective, it will kill almost anything. Although it should 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.

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.
