This product is a ready-to-use solvent-based non-selective weed killer. It contains two active ingredients (hence the name - Knock Out): Bromacil, which controls weeds through root contact and gives season-long residual control, and 2-4-D which controls weeds through foliage and gives immediate weed burn-down. This weed killer is particularly effective in areas where undesirable vegetation is tall and well-established.
