Best Pre Emergent Herbicide For Crabgrass: 10 Options Compared

#1 · Best Overall

1. Scotts Halts Crabgrass Preventer

• Weight: 9.6 lb
• Form: Granule

Best for: Established-lawns seasonal prevention.

Why it ranks #1: The listing says one spring application prevents crabgrass all season, with granular application and specific restrictions for newly seeded lawns.

One spring application is listed to prevent crabgrass all season, giving established-lawn owners a simple seasonal approach to listed weeds. Scotts Halts is a granular preventer, and its fall use also targets winter weeds such as poa annua, henbit, and chickweed.

The granules are intended for application to a dry lawn in early spring, where they prevent germination of crabgrass and other listed weeds rather than eliminate weeds already growing. Scotts also describes fall applications for winter weeds and moss, while noting that rain, snow, or freezing weather after application will not affect performance. That seasonal flexibility suits lawn-care routines planned around spring and fall. Use is limited to established grass; seeding and sprigging have specific waiting periods.

Skip it if you need to treat newly seeded or recently sprigged grass; this product has stated waiting periods before use and reseeding.

A practical fit for owners of established grass who want spring crabgrass prevention and a possible fall weed-prevention application. Its restrictions around seeding and sprigging make it a poor match for lawns undergoing establishment or repair.

#2 · Best Defined Coverage

2. Andersons Barricade Granules

• Weight: 18 lb
• Form: Granule

Best for: DG granules for timed applications.

Why it ranks #2: Its 18-pound granular bag covers up to 5,800 square feet and contains 0.48% prodiamine for crabgrass and other listed weeds.

Patented dispersible granules that break into micro-particles after contact with water give The Andersons Barricade a specific watering-related advantage: the particles move into soil. Its professional-grade pre-emergent targets crabgrass and other grassy and broadleaf weeds when applied in early spring or fall.

The 18-pound granular product lists coverage up to 5,800 square feet, which helps buyers estimate whether a bag suits their lawn. Its 0.48% prodiamine and DG Technology connect the active ingredient with granules that disperse rapidly upon watering and move weed control into soil. Application timing is limited to early spring and fall, and the product prevents weeds rather than eliminating existing ones. It therefore fits planned preventive care, not a rescue treatment for visible weeds.

Skip it if you need to kill weeds already growing; this product is preventive, while Scotts WeedEx Prevent with Halts is also described as preventing germination, not killing existing weeds.

A fit for lawn owners who can time a granular application for early spring or fall and water it in to activate the dispersible granules. Skip it as a solution for established, visible weeds.

#3 · Dithiopyr Formula

3. Yard Mastery Dimension 0-0-7

• Weight: 45 lb
• Form: Granule

Best for: Large lawns wanting potassium.

Why it ranks #3: This granular dithiopyr product lists crabgrass prevention, a 0-0-7 fertilizer blend, and coverage up to 15,000 square feet.

Coverage up to 15,000 square feet pairs with a 0-0-7 fertilizer blend in Yard Mastery Dimension, giving larger-property owners a granular pre-emergent that also supplies potassium. Its dithiopyr formula is listed for preventing crabgrass and broadleaf weeds in early spring or fall.

The 45-pound bag and stated coverage up to 15,000 square feet suit buyers planning a broad lawn application or repeated treatments within that area. Dithiopyr is the named active ingredient for preventing crabgrass and broadleaf weeds before they appear, while the 0-0-7 blend adds potassium to the application. Seasonal use is specified for early spring or fall. The product cannot ship to Alaska, California, Hawaii, or Maine, an important limitation for ordering and planning.

Skip it if you live in Alaska, California, Hawaii, or Maine; Yard Mastery 0-0-7 Prodiamine is another listed granular option without that stated shipping restriction.

A match for owners of larger properties seeking dithiopyr-based prevention and potassium in one granular application. Check the listed shipping exclusions first, and plan use for the specified early-spring or fall window.

#4 · Prodiamine Fertilizer

4. Yard Mastery Prodiamine 0-0-7

• Weight: 45 lb
• Form: Granule

Best for: Rate-conscious prodiamine application.

Why it ranks #4: Its 45-pound granular prodiamine formula is listed to cover 15,000 square feet, with application rates and an annual maximum provided.

A stated recommended rate of 3 pounds per 1,000 square feet makes this Yard Mastery prodiamine granule easier to plan by measured area. The 0-0-7 formula covers crabgrass and poa annua prevention, with a 45-pound bag listed to cover up to 15,000 square feet at that rate.

Its 0-0-7 fertilizer blend combines prodiamine prevention with potassium in granular form, while the stated rate connects the 45-pound quantity to the listed coverage of 15,000 square feet. The directions also give a minimum rate of 2 pounds per 1,000 square feet and a yearly maximum of 6 pounds per 1,000 square feet. Those figures help buyers plan applications within the stated limits; follow the label and avoid exceeding the annual maximum.

Skip it if you want dithiopyr rather than prodiamine; Yard Mastery Dimension uses dithiopyr and lists crabgrass and broadleaf weed prevention.

Suitable for buyers who measure lawn area and want a prodiamine granular product with a stated rate and annual maximum. Its limits matter when planning repeated applications, so calculate totals against the label.

Listed on Amazon as: 0-0-7 Granular Prodiamine Pre-Emergent Herbicide Fertilizer – 45lbs Covers 15,000 sq ft at 3 lbs/1,000 sq ft – Great for preventing crabgrass, POA annua (Annual Bluegrass), and More

#5 · Largest Listed Coverage

5. LebanonTurf Prodiamine 0.58G

• Weight: 40 lb
• Form: Granule

Best for: Broad-area turf maintenance.

Why it ranks #5: The 40-pound granular product contains 0.58% prodiamine and lists coverage of 20,000 square feet for lawn turf and grass.

Coverage of 20,000 square feet per granular application gives LebanonTurf Prodiamine .58G a broad-area role for lawn and turf maintenance. Its 0.58% prodiamine targets crabgrass and other listed grassy weeds, with directions specifying an early-spring application followed by another in late May or early June.

The BIODAC carrier and granular form support application across lawns, turf, and grass, while the stated coverage helps estimate the area served. The directions call for a first application in early spring and a second in late May or early June, so buyers should plan for two seasonal passes. The product is also described for general turf use and landscaping around trees, shrubs, and flowers. Grass seed should not be planted for three to four months after application.

Skip it if you need a single specified seasonal pass; Scotts Halts Crabgrass & Grassy Weed Preventer lists one spring application for all-season crabgrass prevention.

A fit for turf managers covering broad areas who can schedule the specified spring and late-spring applications. The post-application restriction on grass seeding is an important boundary for lawn renovation plans.

#6

6. Scotts WeedEx with Halts

• Weight: 10.3 lb
• Form: Bag

Best for: Weather-tolerant Scotts granules.

Why it ranks #6: This granular pre-emergent targets crabgrass and other listed weeds, with early-spring or fall application and weather-resistant performance stated.

Rain, snow, or freezing weather after application is listed as not affecting performance, a useful scheduling detail for Scotts WeedEx Prevent with Halts. The granular pre-emergent is applied in early spring or fall to prevent germination of crabgrass and other listed lawn weeds.

Scotts lists use on all grass types except dichondra, giving many lawn owners a clear starting point for checking suitability. Its early-spring or fall timing and weather-performance statement support seasonal planning when conditions change after application. The granules prevent listed weeds from germinating; the supplied description does not present them as a treatment for existing weeds. Particles can stain cement, stone, metal, clothing, or shoes, so sweeping hard surfaces and brushing off clothing are relevant cleanup steps.

Skip it if you have dichondra grass; Scotts Halts Crabgrass & Grassy Weed Preventer is listed for established grass, but check its label for your lawn type.

Choose it for seasonal crabgrass prevention on a suitable lawn where weather after application is a scheduling concern. Avoid use on dichondra, and take care to sweep granules from hard surfaces and clothing.

#7

7. Syngenta Barricade 4FL

• Weight: 4 oz
• Form: Spray

Best for: Concentrate users with varied sites.

Why it ranks #7: This 4-fluid-ounce prodiamine concentrate offers a spray format and is labeled for established turfgrass, lawns, and other listed sites.

A 4-fluid-ounce prodiamine concentrate offers a spray-form alternative to granular pre-emergents, for buyers handling labeled lawns, turf, ornamentals, or other listed sites. Syngenta Barricade 4FL is presented for pre-emergent weed control, with application amounts tied to the season.

The spray form and concentrate format suit users who prefer preparing an application rather than spreading granules. The listed use sites include established turfgrasses, lawns, sod nurseries, Christmas tree farms, and ornamentals, giving the product a broad stated setting range. Its prodiamine active ingredient is associated with prevention before weeds germinate. The product details do not provide coverage or mixing rates, so users must rely on the label for appropriate amounts and site-specific directions.

Skip it if you want ready-to-spread granules and a stated coverage area; The Andersons Barricade lists granular form and coverage up to 5,800 square feet.

Consider it if you manage one of its listed sites and prefer a prodiamine spray concentrate over granules. Its missing coverage and mixing figures in the supplied details mean label consultation is central to planning.

#8

8. Lawn Synergy Lesco 0-0-7

• Weight: 50 lb
• Form: Granule

Best for: Potassium blend for turf areas.

Why it ranks #8: The 50-pound granular product contains 0.43% Stonewall, lists coverage of 12,500 square feet, and includes potassium.

A listed four-month protection period pairs with coverage up to 12,500 square feet in Lesco 0-0-7 with .43% Stonewall. This granular pre-emergent includes potassium and is described for preventing weeds in turf grass and landscape beds, giving buyers a defined coverage and duration to plan around.

The 50-pound granular product combines .43% Stonewall with a 0-0-7 formula that includes potassium, so a single application addresses prevention and adds that nutrient. Its stated coverage of up to 12,500 square feet helps match the bag to a lawn or landscape area, while protection is listed for up to four months. Warm-season lawn timing is given as January through March and September through October. The label also prohibits grazing or feeding livestock forage from treated areas.

Skip it if you need crabgrass named specifically among the target weeds; Scotts WeedEx Prevent with Halts explicitly lists crabgrass prevention.

A reasonable fit for turf or landscape-bed owners who value a stated coverage area, four-month protection, and potassium in a granular product. Keep the livestock-forage restriction and warm-season timing in mind.

Listed on Amazon as: Lesco 0-0-7 with .43% Stonewall Pre-Emergent 50 lbs. Covers 12,500 sq. ft.

#9

9. Quali-Pro Prodiamine 65 WDG

• Weight: 5 lb
• Form: Granule

Best for: Tank-mix planning for turf.

Why it ranks #9: This 5-pound prodiamine product lists spring and fall use for crabgrass control and several turf and landscape use sites.

Quali-Pro Prodiamine is listed as an excellent tank-mix partner with fertilizers and iron solutions, making it relevant to buyers coordinating pre-emergent treatment with those applications. Its spring-and-fall use is specified for season-long crabgrass control, alongside pre-emergent grass and broadleaf weed control.

The product lists nurse, landscape, turf, tree, and golf-course use sites, which gives professional and grounds-maintenance buyers several stated settings to consider. Its prodiamine formulation targets pre-emergent grass and broadleaf weeds, including listed species such as poa annua, henbit, knotweed, chickweed, and spurge. Spring and fall application provides the stated crabgrass-control schedule. As with other label-directed herbicides, application rates should come from the label; the supplied details do not state a coverage area.

Skip it if you need a stated coverage area before planning; The Andersons Barricade lists coverage up to 5,800 square feet.

A fit for grounds users coordinating prodiamine with fertilizer or iron applications across listed sites such as turf and golf courses. Its missing coverage figure makes area-based planning depend on label directions.

#10

10. Quali-Pro Generic Barricade

• Weight: 5 lb
• Form: Granule

Best for: Spring-and-fall prodiamine users.

Why it ranks #10: This 5-pound pre-emergent is listed for grass and broadleaf weed control, but the supplied details provide less specific coverage information.

Spring and fall application is specified for season-long crabgrass control, making Quali-Pro Prodiamine 65 WDG a fit for buyers planning prevention around both seasonal windows. The product is identified for pre-emergent grass and broadleaf weed control, rather than treatment of weeds after they appear.

The listed directions call for spring and fall use, while the product features identify crabgrass and broadleaf weed control. That combination gives a buyer a seasonal schedule and a stated range of weed categories to consider when planning lawn or turf prevention. Its granule form is specified, but application rates are not supplied here; the label must guide rates and safety equipment. This option suits label-following users comfortable working from product directions rather than a listed coverage figure.

Skip it if you need a stated coverage area or rate for planning; Scotts Halts Crabgrass & Grassy Weed Preventer lists a one-application spring approach.

Choose it if your prevention routine includes spring and fall applications and you want a granular prodiamine product for grass and broadleaf weeds. It is less convenient when a stated coverage figure is essential to planning.
