Roundup Dual Action Weed and Grass Killer Concentrate 32 oz

Roundup Dual Action Weed & Grass Killer Concentrate tackles two jobs most weed killers split into separate bottles: it kills what's already growing and keeps new weeds from showing up for up to four months. The active ingredient, triclopyr, works on both weeds and grass, and the formula is rain proof once it's dried, so a surprise shower won't wash away your work. This 32-ounce concentrate covers up to 1,600 square feet, making it practical for driveways, sidewalks, patios, and other hardscape areas where weeds tend to creep in through cracks. It's built for multi-season, multi-region use and handles both pre- and post-emergent weeds, so you're not guessing which product to grab depending on the time of year. Use it around established plants you want to keep, but keep it off anything desirable since it doesn't discriminate between weeds and wanted greenery. Made in the USA.
