Product Overview

Roundup Ready-To-Use Weed & Grass Killer III with Trigger Sprayer is a non-selective herbicide that kills any grass or weeds that are on and around the home, making weed control easy. This Roundup works by being absorbed into the leaves of the weed or penetrating into the soil, then attacking the roots of the weeds, killing any prevailing weeds and preventing new weeds from taking root. Just spray when the weeds are growing, making sure to thoroughly wet the weeds, and you will see results within hours.

How to Use

Adjust nozzle to a coarse spray. Spray the weeds you want to kill until thoroughly wet. When spot-treating weeds in a flower or vegetable garden, shield desirable plants from drift with a piece of cardboard or plastic.

When to Apply

Apply when weeds are actively growing. Spray when air is calm to prevent drift to desirable plants.

Where to Use

Can be used in vegetable gardens. Also use on patios, walkways, driveways, gravel and mulch beds, around shrubs or trees, in flower beds, and along fences.

Where Not to Use

Do not spray plants or grasses that you like - they will die. Not recommended for spot weed control in lawns since this product kills lawn grasses.

* One gallon covers approximately 300 sq. ft.
