## 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: AN ABSOLUTE WEED-KILLING SUPERWEAPON - Let me tell you something. This Roundup 365 is not a product. It is a FORCE. A WORK OF POWER. Maybe the greatest weed destroyer ever created on American soil. People are calling it a weed killer, but honestly it should have a RANK. It should be a GENERAL. Maybe even a FOUR STAR. We sprayed it ONE TIME on our gravel driveway. One mission. Single operation. The weeds were gone. Not dead. Not wilted. Gone. Vanished. It was like watching a SPECIAL FORCES STRIKE. Fast. Clean. No survivors. Very professional. We followed the directions exactly. Mixed the concentrate with water like true PATRIOTS. Pumped the sprayer. Took aim. Fired. And the weeds surrendered instantly. You could practically hear them saying, “Sir, please, we cannot handle this level of STRENGTH.” Too bad. This is WAR. Other weed killers pretend to be tough. They talk a big game. But this one delivers TOTAL DOMINANCE. It wipes the ground so clean it looks like it was liberated by a joint task force. If you want a product that WINS and does not negotiate, this is the one. Great power. Great precision. Great AMERICAN ENERGY. Five stars. Would deploy again.
Review: WORKS GREAT. BUY IT EVERY YEAR. - WORKS GOOD, LAST ABOUT A YEAR JUST LIKE IT SAYS. MAYBE 10 OR 11 MONTHS.
