Hi-Yield Killzall Extended Control is a pre- and post-emergent weed killer, so it kills established weeds and prevents weed germination for up to 6 months! Killzall Extended is non-selective, so it's formulated to kill all vegetation. Use near fences, on paths, patios, curbs, sidewalks, driveways, around trees, shrubs, flower beds, and buildings. Weeds will wilt in a matter of days, with a complete kill of most weeds in 1 to 2 weeks. Because Killzall is a non-selective weed control, it's important to keep it off desirable plants, grasses, and vegetation or areas where you plan to plant. 32 oz. concentrated formula.
