## Description

Roundup® Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer Concentrate provides one-step weed protection for up to 12 months. This weed control kills and prevents many types of tough weeds and grasses for up to 12 months, including clover, dandelion, large and smooth crabgrass, poison ivy, and other broadleaf weeds, grassy weeds and brush. It is rainproof in as fast as 30 minutes and produces visible results in hours. Use Roundup® Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer where you want to kill existing weeds AND prevent new weeds for up to 1 year, such as cracks and crevices in driveways, sidewalks, and walkways, patios, paths, and under decks, gravel areas, and other non-lawn areas. Mix the concentrate according to label directions and spot treat or spray evenly each gallon of spray solution over 300 sq. ft. with a tank sprayer. Please note, to prevent new weeds and grasses from growing, YOU MUST SPRAY THE ENTIRE AREA you want to control, NOT JUST the emerged weeds. One 32 fl. oz. bottle makes up to 5.3 gallons (see booklet for mixing instructions) and covers up to 1,600 sq. ft.

Review: This gray jug works, the white ones are weaker and the sprayers don't work. - This one is the real deal! I got tired of wasting my money and time on the white jug of round up only to have to go back and spray weeds again, not to mention the really poor excuse of the sprayers ! I've had to transfer the liquid to my garden sprayer to use the product. This has happened the last 3 or 4 times I have purchased it. This time I finally got a positive experience. It was more expensive but actually saved time and money because it actually works as advertised !
Review: Reliable fast acting weed killer - I’ve used a lot of weed killers over the years, and this one definitely delivers. The Roundup Dual Action 365 is incredibly easy to use, especially with the attached sprayer—no mixing, no hassle, just grab and go. It works quickly on weeds and, what I really appreciate, it helps prevent new growth for months. I’ve used it around my walkway and front porch area, and it keeps everything looking clean and maintained without constant reapplication. The delivery was smooth and on time, and the packaging was secure. Overall, this is a dependable product that saves time and effort—especially if you want longer-lasting results without frequent upkeep. Highly recommend for anyone trying to stay ahead of weeds without making it a weekly chore!
