Trying to kill Japanese knotweed that I have removed and prevent any regeneration.
We recommend contacting the manufacturer Dow AgroSciences at 800-992-5994 to see if you can use this product in soil. Battleship is our most popular herbicide for knotweed control. Battleship III gives you superior post-emergent control of tough broad-leaf weeds on lawns and other landscaped areas. Its 2,4-D free formulation is effective in cool and warm-season turf. The advanced "three-way" formulation contains Triclopyr, Fluroxypyr and MCPA in an easy-to-use liquid formulation.
