/u/kubigjay has a point, laser only kills what is above ground and it is well known that weeds root also damages the crops.

That is not correct. If any root pieces are left underground they will eventually grow new plants. You should be pulling the whole sprouts out to basically starve the weeds. Or, obviously, use chemicals to stop them from growing.
