The Roundup brand of glyphosate herbicide can be a very effective tool for homeowners who want to renovate a tired weedy lawn. Roundup and other brands of glyphosate herbicide are mixed with water and sprayed on plant leaves. The herbicide migrates from the leaves to the roots for a complete kill. Glyphosate kills plants by preventing them from making certain amino acids essential for plant respiration and growth.
Kills Everything
-
Roundup is a nonselective herbicide that kills all vegetation including most species of lawn grasses. Homeowners use Roundup to kill existing grass and weeds on a lawn before reseeding or laying new sod. Roundup kills annual and perennial lawn grasses. Mix Roundup concentrate at a rate of 6 ounces per gallon of water, and spray on your lawn during a warm sunny day. Annual grass should wilt and die within two to four days after application. Perennial grasses will take seven to 10 days to die.
