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.
Where not to use
Do not spray plants or grasses that you like - they will die. Do not use in lawns or for lawn renovation as Roundup Extended Control prevents desirable grasses from growing too. Do not use for vegetable garden preparation or in and around fruits and vegetables. Do not spray around young plants or in an area that will be planted or seeded within 4 months.
For weed control in your lawn, try Roundup® For Lawns.
When to apply
Spray when air is calm to prevent drift to desirable plants. For best results apply during warm sunny weather above 60 degrees F. Rain or watering 30 minutes after application will not wash away effectiveness.
