This can control bamboo, but we would recommend either a Imazapyr or Glyphosate product. Weed Blast would kill anything that it’s put on (Imazaoyr will also do this) so if their any desirable plants we do not recommend either. Spray solutions also seem to work better when applied to bamboo that was mowed or chopped and allowed to regrow to a height of approximately 3 feet, or until the leaves expand. If there are any desirable plants nearby, use Glyphosate. If not, then use an Imazapyr product.
