Spike 20P Herbicide is not specifically labeled for bamboo. Bamboo is extremely stubborn, so it can take several steps to remove it completely. You can use Round Up QuickPro at the highest listed usage rate to help eliminate bamboo. You will be required to cut the bamboo down to a short stump and then apply the Round Up QuickPro. It can take several applications to achieve the desired results.
