## Description

Root out the toughest weeds and grasses with Roundup® Dual Action Weed & Grass Killer Plus 4 Month Preventer Concentrate. This formula kills existing weeds and grass down to the root, and prevents new weeds from growing for up to 4 months by creating an invisible barrier in the soil. Apply only where you want to kill existing weeds AND prevent future weed growth for up to 4 months, such as cracks and crevices in driveways, sidewalks, and patios, along fences, in mulched beds or around the base of well-established desirable plants, shrubs, or trees, and on gravel areas. In order to prevent new weeds and grasses from growing, you must spray the entire area you want to control, not just the emerged weeds. For best results, apply during warm, sunny weather above 60°F. Rain or watering 30 minutes after application will NOT wash away effectiveness. After application, weeds will begin to yellow and wilt within hours with complete kill in 1 to 2 weeks. All ornamental bedding plants (annuals and perennials), trees, shrubs, sod and seed can be planted 4 months after application. Roundup® Dual Action Concentrate covers up to 1,600 sq. ft.

Review: Quality concentrate - Nothing compares to Round up. I have used cheaper stuff in larger bottles, only to find out with the mix ratio, it makes the same amount this bottle does in the end. This is a small bottle, and it’s pricey, but it works, it’s noticeable quickly, and used properly it keeps the weeds away for a good while. Must spray bare areas to prevent new growth too. I use this on areas where there is nothing I can accidentally kill because it’s too potent, I’ll save the cheaper stuff for the grass around edges or plants. Package didn’t leak and was sealed upon delivery. Easy to mix and use the entire jug quickly when you are making up 5 gallon batches at a time. Everything I sprayed with this, it killed. Even some small tree’s. Didn’t have issues like I did with other sprays.
Review: Worked Well on Stubborn Greenbriar - This Roundup Dual Action Weed & Grass Killer worked rather well for greenbriar, which is exactly what I needed it for. Greenbriar is one of those stubborn, annoying weeds/vines that seems to keep coming back, so I was glad to see this actually make a noticeable difference. I like that this is a concentrate, because it gives you more product to work with and is useful if you have a larger area or multiple spots to treat. It is not something I would use casually around plants I want to keep, since it is a weed and grass killer, but for problem areas where I want the growth gone, it has been helpful. The added 4-month preventer is also a nice feature, especially in areas where weeds keep popping up again. For tough overgrowth, fence lines, driveway edges, wooded edges, and places where greenbriar likes to take over, this seems like a practical option. Overall, I was pleased with how it worked. Greenbriar can be a pain to deal with, and this made the job easier.
