Crossbow Herbicide could possibly harm holly but it is not labeled for this plant so we cannot recommend it for controlling/killing it. Holly shrubs would need to be treated like trees, in which case you would cut the shrubs down to stumps and then treat the fresh cuts. Crossbow Herbicide is labeled for the control of most kinds of unwanted trees. On page 5 of the label you can find directions on how to use for conventional basal bark and stump applications.
