Clarence from New Roads, La. writes
If you are wanting to completely kill the tree, you must kill and remove the stump. To kill a sycamore stump use a stump grinder to grind the stump down to ground level. You will then dig it out with the connecting roots. You could use a stump killer such as Fertilome Brush Killer and Stumper Killer to the newly cut stump within a few minutes after cutting. You would still need to do your part to remove the stump but the Fertilome Brush Killer and Stump Killer will prevent resprouting.
