Crossbow Herbicide is not labeled for bamboo. However, we have heard that if you cut down the bamboo level with the ground and apply Crossbow or a similar Triclopyr based product undiluted to the fresh cut it can help kill it out. Bamboo is extremely stubborn, so it can take several steps to remove it completely. You can also 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. Roundup can also be used for the asparagus fern as there is not currently anything actually labeled for it. We did find an article here that might help.
