Arsenal AC Applicators Concentrate Herbicide is labeled for japansed bamboo however been discontinued by the manufacturer.  Using a non selective glyphosate product like Roundup Quick Pro or a Stump/Root killer containing Triclopyr is effective as stump treatment method.   One application won't eradicate the infestation; bamboo is tough and has a tendency to spread like wildfire. As the bamboo continues to send up shoots, you'll need to continually apply the herbicide treatment to the leaves, stalks, and shoots of the plant in order to properly exterminate it. You should also use this herbicide method in conjunction with rooting out the rhizomes of the bamboo, so that it doesn't keep sending up shoots. Step 1. Cut the bamboo down to soil level in late winter and wait for new shoots to grow back in late spring/ early summer. Bamboo herbicide won't be effective if the canes of the bamboo are well-developed. Step 2. Using a shovel, cut off any underground rhizomes when new shoots start to grow bac. Break up as many clumps of rhizomes as possible. Step 3. Apply glyphosate or triclopyr active ingredient herbicide directly to freshly cut stumps or any regrowth. Step 4. Repeat treatment to new shoots or new growth as needed
