Knockdown - Broad Spectrum Weedkiller

Knockdown® Weedkiller controls a wide range of grass and broadleaf weeds including couch, kikuyu, paspalum, thistles and most oxalis species. It works by moving through the plant and into the root system killing the entire plant. Brown-off may take 7–14 days after application, depending on growing conditions. 

Knockdown® Weedkiller leaves no soil residue so treated areas may be sown immediately after weeds have died. Knockdown® Weedkiller has no soil activity and can be used for spot treatment of weeds in rockeries, paths, garden beds, lawns and around buildings.
