Bamboo is extremely stubborn, so it can take several steps to remove it completely. Per the label, you will apply Arsenal AC Applicators Concentrate Herbicide
at a rate of 1.5 to 2.0 pints/A applied to the foliage when plant is actively growing; before setting seedhead. More foliage will result in greater herbicide uptake, resulting in greater root kill. Please see the label for full application instructions.
