Ortho GroundClear Weed & Grass Killer is a ready-to-use herbicide designed to protect your landscape from unwanted weeds and grasses. This Costco 2-pack includes two 1-gallon bottles, each equipped with a battery-powered Comfort Wand applicator that delivers a continuous, hands-free spray for precise and comfortable application.

The formula acts on contact with visible results in as little as 15 minutes and becomes rainproof within 2 hours upon drying. It controls a wide range of common weeds and grasses including dandelions, chickweed, spotted spurge, moss, crabgrass, oxalis, algae, annual bluegrass, and perennial ryegrass. The active ingredient is ammonium nonanoate, and the product is OMRI listed for organic use.

Ideal for use on weeds in and around walkways, driveways, under trees, and in landscape beds. Apply when weeds are small, actively growing, and dry. Do not allow spray to contact desired plants. Not intended for use on food plants. Keep children and pets out of the application area until sprays have dried. Multiple applications may be required for control of certain weeds and grasses.
