Green Light Amaze Grass and Weed Preventer is not labeled for bamboo. Since bamboo roots go so deep, you would need to apply either a product like Rodeo/Roundup QuikPro at the highest rates directly to the fresh cut stump of the bamboo after you cut it down level to the ground, or use a brush and stump killer undiluted directly on the fresh stump.
