Additional Information About Hi-Yield Killzall Weed and Grass Killer - 41% Glyphosate


Hi-Yield Killzall Weed & Grass Killer Super Concentrate containing 41% glyphosate is a broad spectrum herbicide spray that completely kills all types of broadleaf and grassy weeds and many other plants down to the roots.

How It Works

Hi-Yield Killzall Weed & Grass Killer enters plants through foliage moving down to the roots, killing weeds by stopping the production of a substance found only in plants that is vital for survival. Weeds start yellowing within days with a complete kill in 1 to 2 weeks.

Extra Tips

  • For best results, apply when weeds are actively growing and temperatures are above 60 degrees

  • Safe planting of ornamental plants can begin after spray has dried completely on weeds in planting area (minimum of 2 hours)

  • Do not spray this product on desirable plants or lawns unless you intend to kill them

  • Spray on a calm day to avoid spray drift to and on desirable plants

  • For spot spraying loosen sprayer nozzle to shoot stream rather than fog

  • To avoid spread of weeds by seed, spray weeds before they begin to produce seed

  • Do not spray near garden ponds, lakes or other bodies of water as this product is harmful to aquatic life
