Dichlobenil, the active ingredient in Casoron 4G Herbicide, is not labeled for bamboo and may not be an effective solution for your needs. We recommend a product like Rodeo or 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.
