Hi-Yield Killzall Weed & Grass Killer

Non-selective means this product will kill or damage almost any green plant it touches, including your lawn grass, flowers, and shrubs. You should use it carefully only in areas where you want to eliminate all vegetation, such as gravel driveways or cracks in sidewalks.

While results can vary based on weather conditions and the type of weed, you will typically start to see wilting and yellowing within a few days. The systemic action works by traveling to the root, so complete death of the plant usually occurs within one to two weeks.

You should exercise extreme caution. Because it is non-selective, any spray drift or accidental contact with your desirable plants will likely kill them. It is best used for edging or clearing areas where you do not want any plant life to grow.

No, this is a post-emergent herbicide, meaning it only kills the weeds that are currently actively growing. It does not have residual soil activity, so it will not prevent new seeds from germinating in the future.

Because this is a super concentrate, you must mix it with water according to the specific ratios listed on the product label. Always follow the dilution instructions carefully to ensure you are applying the correct strength for your specific weed control needs.
