Best Crabgrass Killer For Lawns: Compare 10 Options

#1 · Best Overall

1. BASF Drive XLR8

• Weight: 4.2 lb
• Form: Liquid

Best for: Fast-uptake post-emergent control.

Why it ranks #1: Its quinclorac concentrate targets emerged grassy weeds, offers up to 30 days of residual control, and is rainfast in less than an hour.

Its water-based formulation supports faster plant uptake, giving lawn owners a post-emergent option for grassy and broadleaf weeds. BASF Drive XLR8 uses quinclorac and offers up to 30 days of residual control, with rainfastness in less than an hour after application.

The water-based liquid formulation is identified as supporting faster uptake, which suits buyers treating weeds already present rather than relying only on prevention. Quinclorac provides grassy and broadleaf weed control, while the stated residual period of up to 30 days may reduce how often another application is needed. Rainfastness in less than an hour can also help when weather threatens to interrupt a treatment schedule. This is a concentrate, so application involves mixing rather than using a ready-to-spray product.

Skip it if you want a granular crabgrass preventer with lawn food; Scotts Turf Builder Halts combines prevention and fertilizer.

Choose this concentrate if you need post-emergent control for lawn and turf weeds and value a short rainfast window. Its liquid concentrate format means you should be prepared to mix it before use.

Why it ranks #2: The concentrate controls crabgrass and more than 200 listed broadleaf weeds, works down to the roots, and is rainproof in one hour.

Skip it if you need broadleaf weed control alongside crabgrass; Spectracide Weed Stop for Lawns Plus Crabgrass Killer lists both weed types.

Choose this liquid for actively growing crabgrass and grassy weeds when your lawn is among the listed grasses. Its 24-hour rain restriction and three-week reapplication interval require careful scheduling.

• Form: Liquid

Best for: Contact-action nutsedge control.

Why it ranks #7: This ready-to-spray lawn treatment targets crabgrass, nutsedge, and more than 100 other listed weeds, making it useful for mixed weed problems.

Contact action paired with root-level weed control gives Image Herbicide a dual approach for crabgrass, nutsedge, and other listed lawn weeds. The ready-to-spray liquid is identified for established lawns and is described as not harming grass when used as directed.

Image targets crabgrass and yellow and purple nutsedge, alongside dandelion, clover, and more than 100 other listed weeds. Its contact-starting action offers a visible-growth treatment approach, while the stated root kill addresses tough weeds beyond their surface growth. The ready-to-spray format avoids the concentrate-mixing step and is intended for established lawns.

Skip it if you want a granular pre-emergent application; Scotts Turf Builder Halts Crabgrass Preventer pairs prevention with lawn food.

This suits owners of established lawns facing crabgrass, nutsedge, and broadleaf weeds who prefer ready-to-spray treatment. Its stated lawn-use fit is established grass, so it is not aimed at newly seeded areas.

#8

8. Bug And Blade Drive XLR8 Kit

• Weight: 5 lb
• Form: Liquid

Best for: Drive XLR8 concentrate kit.

Why it ranks #8: The kit includes 64 fluid ounces of BASF Drive XLR8 concentrate and disposable boot covers, but its listed facts provide less application guidance than the original.

The two-piece kit pairs BASF Drive XLR8 concentrate with disposable boot covers, giving buyers the named herbicide and protective accessories together. The product title identifies it as a post-emergent quinclorac treatment with 30-day residual control for Bermuda, Zoysia, and Fescue turf.

This kit centers on BASF Drive XLR8 concentrate, identified in the title as a post-emergent crabgrass killer containing quinclorac. The same title states 30-day residual control and names Bermuda, Zoysia, and Fescue turf, which helps buyers assess its intended lawn fit. The included disposable boot covers add a handling accessory to the concentrate package. Because the supplied product information does not provide mixing or application directions, buyers should consult the herbicide label for those steps.

Skip it if you need a ready-to-spray weed killer; Image Herbicide Crabgrass, Nutsedge, & Weed Killer is listed as ready-to-spray.

This kit fits buyers seeking Drive XLR8 for post-emergent crabgrass treatment on the named turf types, with boot covers included. Check the label for application details, since directions are not supplied here.

#9

9. Scotts Turf Builder Halts

• Weight: 13.4 lb
• Form: Granule

Best for: Spring prevention with lawn food.

Why it ranks #9: This granular pre-emergent prevents crabgrass and includes lawn food for a 5,000-square-foot area, but it is for prevention rather than emerged weeds.

Crabgrass prevention paired with lawn food gives Scotts Turf Builder Halts a dual role: it aims to stop crabgrass before it invades while feeding grass for a fast green-up after winter. Its granules cover a stated 5,000 square feet.

As a pre-emergent granule, this product is aimed at preventing crabgrass before it appears, rather than treating established weeds. The lawn-food component adds a feeding step to the same application, with the stated aim of supporting fast green-up after winter and stronger, deeper roots. Rain, snow, or freezing conditions after application are not said to affect performance. The product calls for rainfall or watering of 1/4 to 1/2 inch within two to three days for best results.

Skip it if you need control after crabgrass emerges; Preen Lawn Crabgrass Control also offers limited post-emergence control of seedlings.

A practical fit for homeowners planning a spring application who want crabgrass prevention and lawn feeding together. It is not the choice for emerged crabgrass, and best results call for watering within the stated window.

#10

10. Scotts Halts Preventer

• Weight: 9.6 lb
• Form: Granule

Best for: Seasonal grassy-weed prevention.

Why it ranks #10: Its granular application prevents crabgrass germination when applied in spring, but it does not serve buyers seeking to kill existing crabgrass.

One spring application is intended to prevent crabgrass for the season, making Scotts Halts a straightforward choice for prevention-focused lawn care. Its granules also have a fall role against listed winter weeds such as poa annua, henbit, and chickweed.

The product is a germination preventer, so its practical role is stopping listed weeds before they establish rather than killing visible crabgrass. Spring application targets crabgrass and other listed problem weeds for the season, while fall use addresses winter weeds including poa annua, henbit, and chickweed. The granules can remain effective despite rain, snow, or freezing weather after application. However, the label restricts use on newly seeded lawns until after the fourth mowing, an important planning boundary.

Skip it if you need to treat crabgrass already growing; Roundup for Lawns Crabgrass Destroyer2 targets actively growing grassy weeds.

This suits owners planning seasonal prevention on established grass, with spring and fall uses for different listed weeds. Avoid applying to newly seeded lawns before the label's fourth-mowing threshold.
