Roundup Dual Action Weed & Grass Killer — 1.33 gal with Sure Shot Wand, 4-Month Preventer, Concentrated Ready-to-Use

Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer with Sure Shot Wand quickly kills weeds and grasses down to the root and creates a soil barrier that helps prevent new growth for up to four months.

This concentrated 1.33-gallon ready-to-use solution combines an immediate contact action with a longer-lasting soil protectant, designed for hardscape edges, gravel, and mulched beds where you want existing weeds eliminated and new ones suppressed. The included Sure Shot Wand helps focus the spray so you can treat specific areas—driveways, sidewalks, patios, fence lines, and around established ornamentals—while minimizing overspray. One container treats up to about 400 square feet when applied as directed.

How fast will I see weeds die after applying Roundup Dual Action?

Visible decline often begins within hours and most treated weeds and grasses will be brown and wilted within one to two weeks. Speed depends on temperature and plant type; warmer, sunny conditions above 60°F promote quicker uptake and visible symptoms.

• Initial yellowing and wilting can start as fast as 6 hours.
• Complete browning and die-back usually occur within 1–2 weeks.
• Apply when daytime temperatures are consistently above 60°F for best response.

Where should I use this product and how should I apply it?

Use on non-crop surfaces and landscaped areas where vegetation control is desired: hardscapes, gravel, mulched beds, around established ornamentals, and along fence lines. To prevent new weeds, spray the entire target area—not just the visible weeds—so the product can form its barrier in the soil.

• Apply uniformly across the area you want to keep weed-free for prevention.
• Use the Sure Shot Wand to concentrate spray and reduce drift onto desirable plants.
• Do not spray where new seeds or sod are planned until the recommended waiting period ends.

How long does the prevention last and when can I replant?

The product helps prevent new weed and grass emergence for up to four months under normal conditions. After four months you can safely plant ornamental bedding plants, trees, shrubs, sod, or seed as directed on the product label.

• Up to 4 months of residual prevention in treated soil.
• Ornamentals, trees, shrubs, sod and seed may be planted four months after application.
• Effectiveness can vary with soil type, rainfall, and how thoroughly the area was treated.

Will rain or watering affect performance?

This formula is designed to become rainfast quickly; light rain or irrigation 30 minutes after spraying will not eliminate activity. For reliable results, avoid applying during heavy wind or imminent heavy storms and follow label directions for weather conditions.

• Rainproof in as fast as 30 minutes after application.
• For best results, apply in warm, calm, sunny conditions.
• If heavy rain occurs immediately after spraying, consider re-treating according to label guidance.

Who is this for? Homeowners, property managers, and maintenance crews who need quick knockdown of existing weeds plus a multi-month barrier to reduce recurring growth will benefit from Roundup Dual Action. It suits areas where you want long-lasting suppression but not continuous vegetation — driveways, walkways, patios, gravel driveways, and mulched or landscaped beds around established plants. Always read and follow label directions and safety instructions before use to ensure proper application and protection of desirable plants.
