## 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: A great product! - I have used this version of Roundup for the past 3 or 4 years. It quickly kills the weeds that are sprayed. It also really does keep new weeds from sprouting in the sprayed area for about 4 months. This concentrated product is the most economical way to buy Roundup, as 1 bottle will make a little over 5 gallons of spray. It is easy to apply with a garden sprayer and is rainproof shortly after application. Just be sure not to spray anything that you don't want to kill.
Review: It is Roundup it works for everything - Really food product, I used it and by the second day I could see the weeds and unwanted grass dying off, will have to see if this is as advertised on the 4 month period as this is the first time I am using this.
