Features & Benefits

Ideal for Large Areas

Roundup brand concentrate products offer additional value and are great for treating larger areas. Use of a Roundup branded tank sprayer is recommended and available in several sizes.

Economical Way to Treat Weeds

Simply add water to the amount of concentrate called for on the label — easy, effective and economical to treat large areas. Mix according to directions.

35.2 fl. oz. covers up to 6,900 sq. ft., 1/2 gallon covers up to 12,750 sq. ft. and 1 gallon covers up to 25,500 sq. ft.

it works much better than others
4 Stars
it works much better than others
I used other less expensive brands in the past and they were not as effective. You would see some browning and they would bounce back. But with this, it went brown from tip to toe in 3 days. And you only need to spray it on the leaves. I would stay far away from any garden vegetable though.This also will kill any grass near the weed, don't spray too wide or you'll end up with dead spots in your lawn. Minus one star, not as targeted as I thought it would be. One option is to use Scott’s fertilizer, it has a weed killer component, sprinkle the grass fertilizer in the leaves. Or just yank the weed out, use a long flathead screwdriver to dig into its root.
