It is slow to act and now the watershield is rotting away. I think next year I may just use a bag or two Navigate as soon as the watershield first starts to grow in the spring. May work well if I just hit every bank I want to clear for a supressive effect.
Good deal. Systemic herbicides can take a few weeks to work.
