As of 2015, the mixing directions for Roundup herbicide concentrate products, such as the Concentrate Plus and Super Concentrate concentrates, are to mix the appropriate number of ounces with a gallon of water. Each type requires a different dosage of concentrate, with the Concentrate Plus recommended dose being 6 ounces per gallon and the Super Concentrate recommended dose being 2.5 ounces per gallon. Roundup's Weed and Grass Killer concentrate products are used with a tank sprayer.
Roundup concentrate products are able to remove a large variety of weeds and grass, including both mature vines and smaller seedlings, when it is properly mixed. Roundup concentrates are also recommended to be mixed inside a gallon tank sprayer that is either lined with plastic or made of fiberglass.
Roundup also carries a range of other weed and grass removal products that do not require the addition of water for mixing. These products include the Ready-to-Use Weed and Grass Killer III, the Max Control 365, the Poison Ivy Plus Tough Brush Killer and the Extended Control Weed and Grass Killer Plus Weed Preventer II. Roundup's line of weed and grass removal products are designed to solve various scales of weed problems and can be applied in both soil-covered and paved areas.
