Roundup Concentrate Extended Control Weed & Grass Killer Plus Weed Preventer
Ideal for large jobs.
Kills the Root! Guaranteed.
Dual-action formula kills existing driveway and patio weeds and keeps new ones from growing for up to 4 months.
HOW TO USE
Use of a Roundup branded tank sprayer is recommended. A plastic, fiberglass, plastic-lined steel or stainless steel sprayer can be used. Do NOT apply with a galvanized or unlined steel (except stainless steel) sprayer or through any irrigation system. Add 6 fl. oz. (12 Tbs.) to 1 gallon of water. Spray the existing weeds AND the entire surrounding weed-prone area you want to keep free of weeds for up to 4 months. Spray the area until THOROUGHLY WET. When spraying around the base of well-established (at least 6 months old) ornamental plant, shrubs, or trees shield desirable plants from drift with a sheet of cardboard or plastic. If a desirable plant is accidentally sprayed, rinse off immediately with water. People and pets may enter treated areas after spray has dried.
WHEN TO APPLY
Spray when air is calm to prevent drift to desirable plants. For fast visible results apply during warm sunny weather (above 60 degrees F). Rain or watering 30 minutes after application will not wash away effectiveness.
KIDS AND PETS
People and pets many enter treated area after product has dried. Glyphosate targets an enzyme found in plants but not people or pets”
