BASF Drive XLR8 Crabgrass Killer
This post-emergent product is designed for turf and broadleaf weed control with a water-based formulation that promotes faster plant uptake. It provides up to 30 days of residual control and becomes rainfast in less than an hour. Best for lawns dealing with crabgrass and a mix of broadleaf weeds such as dandelion and clover. Choose this if you want longer-lasting weed suppression without frequent reapplications. Caution: Not ideal for non-turf areas like garden beds or under heavy shade where crabgrass is not the primary issue.
Ortho GroundClear Weed & Grass Killer
Designed for fast, broad coverage, this ready-to-use spray kills both weeds and grasses on contact and provides rainproof protection after drying. It’s well-suited for pathways, driveways, and landscape beds where crabgrass and other creeping weeds invade. Best for homeowners who want quick, spray-and-go results with minimal mixing. Limitation: It’s a broad-spectrum product, so apply carefully to avoid desirable plants and turf nearby.
Ortho WeedClear Lawn Weed Killer Ready-To-Spray
This hose-end formulation targets weeds in lawn areas, including crabgrass, dandelion, clover, and chickweed. It’s fast-acting, with visible results typically after a single application. Best for homeowners who want simple, dial-and-spray control over large lawn areas. Caution: Use only on labeled turf species; avoid applying on ornamentals or susceptible plants within the spray radius.
Roundup for Lawns Crabgrass Destroyer2
This ready-to-use formula is designed to kill crabgrass and other grassy weeds to the root. It’s formulated for use on common Kentucky bluegrass, fescue, and ryegrass varieties. Best for homeowners seeking a readily accessible solution that targets stubborn lawn weeds without complex mixing. Limitation: May be less effective on dense weed patches or very mature crabgrass without multiple applications.
Spectracide Weed Stop For Lawns Plus Crabgrass Killer
Spectracide’s ready-to-use formula targets a wide range of weeds, including crabgrass, dandelion, chickweed, clover, and yellow nutsedge. It promises visible results in as fast as 5 hours, making it a strong option for quick lawn improvement. Best for homeowners who want rapid, noticeable weed reduction with a simple spray. Caution: Check for listed weed types to ensure your target species is included, and avoid unintended plant contact.
Buying Guide
Key purchase considerations help tailor choices to lawn type, weed pressure, and application style.
- Lawn type and area: Choose ready-to-use sprays for small areas or hose-end products for wide lawns. Concentrates work well for large or repeat applications when you want to control cost and timing.
- Target weeds: Confirm crabgrass is on the label and look for broadleaf weed control if dandelions, clover, or chickweed are present.
- Residual and rainfastness: Longer residuals reduce reapplication frequency but may increase non-target impact. Rainfast time matters for weather windows after application.
- Turf safety: Check compatibility with your grass type (bluegrass, fescue, ryegrass). Some products are gentler on cool-season grasses than others.
- Application method: Hose-end sprays are quick for broad areas; backpack concentrates require mixing and equipment but can be economical for large yards.
