What it does for your lawn

• Pre- and post-emergent crabgrass control—limits germination and early growth up to the third leaf stage.
• Controls or suppresses additional grassy and broadleaf weeds when applied before they germinate, including barley, chickweed, oxalis, spurge, foxtail, dallisgrass, goosegrass, and more.
• Designed for use on both cool- and warm-season grasses; tolerant species include Kentucky bluegrass, tall and fine fescues, ryegrass, bermudagrass, and carpetgrass.
• Safe around ornamentals—protects 100+ ornamental plants listed on the label; avoid plants grown for food.
• Complete coverage for up to 5,000 sq ft per 10 lb bag; best applied in spring or fall before weed germination begins.

Where to use it

• Ideal for home lawns featuring common cool- and warm-season grasses, helping prevent weed encroachment during peak seasons.
• Useful around landscape beds and paths where ornamental plants grow in proximity to turf.
• Particularly effective as a preventive step in early spring and autumn when many weeds begin to emerge.

Note: Do not apply to plants grown for food. Always follow label directions for application rates and safety guidelines to achieve the best results for your specific lawn.
