How Dimension 2EW Pre-Emergent Herbicide Works

Dimension 2EW Pre-Emergent Herbicide contains dithiopyr, a chemical in numerous pre-emergent herbicides that prevents crabgrass and other invasive grasses and weeds from sprouting. Though it works as a pre- and post-emergent herbicide on crabgrass, it provides season-long control of chickweed, London rocket and other grasses and broadleaf weeds. It contains a nonstaining, low-odor formula and works in single and split applications.

  • Container-grown ornamentals
