What makes it effective

• Kills weeds and grasses from the leaves down to the root.
• Prevents regrowth for up to five months after one application.
• Makes it easy to mix with water and apply as directed for scalable coverage.

Best uses and practical tips

Ideal for clearing vegetation along walkways, driveways, and patios, including cracks and edges. Avoid spraying desirable plants such as lawn grasses, shrubs, or trees. For best results, apply during warm, sunny weather when weeds are actively growing and temperatures exceed 60°F.

• Coverage: 32 ounces treats up to 500 square feet when diluted per label directions.
• Weather considerations: rain is not a major issue within one hour of application once the spray has dried.
• Re-entry: pets and people may re-enter treated areas after the spray dries.
