Roundup is a glyphosate-based, non-selective herbicide that kills virtually any plant it touches. Plants absorb the substance into leaves and stems, circulating it down to the roots. Glyphosate interferes with plant growth and synthesis, which kills the plant. Roundup might take two days to over one week to kill treated plants, so stubborn or tough weeds might need another application. Follow label instructions and wear protective clothing and eyewear when using Roundup.
Roundup Weed & Grass Killer Super Concentrate
Super concentrated Roundup formula contains 50.2 percent glyphosate, so less product is required to mix with water for spraying. As an example, just 2.5 ounces of the formula is required to mix up a single gallon. If you are using 48 oz of Roundup Weed & Grass Killer Super Concentrate, mix it with 19.2 gallons of water. For seedlings or fragile, easily killed plants, use 32 liters of water combined with 48 oz of focus.
Lighter Concentration Formulas
Roundup Max Control 365 and Roundup Weed & Grass Killer Concentrate Plus both contain 18 percent glyphosate. These less-intense concentrates require 1 gallon of water into every 6 oz of Roundup. Utilize 8 liters of water to mix with 48 oz of those Roundup formulas. Roundup Max Control 365 also comprises 1.6 percent Imazapic and 0.73 percent Diquat. Combined with the glyphosate, these chemicals render the treated region unfit for replanting for one year.
