Roundup Dual Action Weed & Grass Killer Plus Concentrate (32 fl. oz.) provides powerful, long‑lasting vegetation control by combining fast‑acting systemic weed kill with extended soil barrier protection. Designed to eliminate tough annual and perennial weeds down to the root, this dual‑purpose formula also prevents new weeds and grasses from emerging for up to four months, making it ideal for hardscapes and landscaped areas. Rainproof within 30 minutes and delivering visible results in as little as six hours, this concentrate is easy to mix and apply using a tank sprayer. Perfect for homeowners seeking reliable, extended weed control with professional-level performance.


Key Benefits

Dual‑action formula kills and prevents; fast rainproof protection; extended 4‑month weed prevention; systemic root kill; suitable for a variety of non-lawn areas.

Where to Use

Cracks and crevices in driveways and sidewalks; patios; gravel areas; along fences; mulched beds; around well‑established shrubs and trees; landscaping borders. Not for use on lawns.

How It Works

Kills existing vegetation by systemic absorption through leaves and stems, moving throughout the plant to destroy roots. A soil barrier forms to prevent new weeds and grasses from germinating.

Application Instructions

Mix 6 fl. oz. of concentrate per 1 gallon of water.
Apply with a tank sprayer to thoroughly cover the treatment area.
To prevent new weeds, spray the entire area—not just the visible weeds.
Apply during warm, sunny weather above 60°F for best results.
Rain or watering 30 minutes after application will not reduce effectiveness.

Visible Results

Initial yellowing and wilting may appear within 6 hours; full kill typically occurs within 1–2 weeks depending on weed type and conditions.

Replanting Guidelines

All ornamental bedding plants, trees, shrubs, sod, and seed may be planted 4 months after application.

Coverage

32 fl. oz. concentrate treats up to 1,600 sq. ft. when mixed according to label rates.

Safety Information

Keep people and pets away from treated areas until spray has dried. Avoid drift onto desirable plants. Always follow label precautions and mixing instructions.
