What Herbicide can I use to kill Japanese Knotweed?


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.
