## Description

Roundup® Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer with Comfort Wand® 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. The Comfort Wand® is true to its name. With one-touch continuous spray there is no more tired, aching hands. 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 1 gal. container treats up to 300 sq. ft.

Review: Rain came early, but RoundUp still came through - I applied Roundup 365 to a gravel walkway that had been overrun with weeds. About an hour later, the skies opened up with unexpected rain, and I thought for sure I’d have to start all over again. But nope — this stuff still worked. Within a few days, the weeds were shriveled up and dying off exactly as promised. It’s been several weeks now, and nothing has come back. Not even a hint of green. I’m seriously impressed by how long-lasting and effective it is, even with less-than-perfect conditions. Pros: ✔️ Kills weeds fast ✔️ Lasts a long time ✔️ Rain an hour later didn’t ruin it ✔️ Great for driveways, walkways, and fence lines Cons: ❌ None so far — just make sure you apply carefully and avoid any plants you don’t want dead Definitely a repeat purchase. If you're serious about keeping weeds away for good, this is your product.
Review: Works exactly as we hoped. - We often purchase this product. It can cover large areas covered with weeds - it can effectively remove the weeds and the effect is rapid, without affecting other plants.
