Best Pre Emergent For Lawn: Compare 10 Lawn Weed Preventers

#1 · Best Overall

1. The Andersons Barricade Granular

• Form: Granule

Best for: DG granule lawn-care users.

Why it ranks #1: Its 0.48% prodiamine targets grassy and broadleaf weeds, while the 40-pound bag states coverage up to 12,880 square feet.

Patented Dispersible Granular technology turns each Barricade granule into thousands of micro-particles on contact with water, helping move prevention into the soil. The Andersons product contains 0.48% prodiamine and targets grassy and broadleaf weeds, making it a spring-or-fall option for established turf and landscape areas.

The 40-pound granular product covers up to 12,880 square feet, giving lawn owners a defined area for planning application. Its DG technology disperses rapidly when watered, so granules transition into smaller particles rather than remaining intact on the surface. Prodiamine targets weeds including crabgrass, poa annua, goosegrass, and henbit. Use it as prevention, not a rescue treatment: the product will not eliminate existing weeds, and application timing in spring or fall matters to performance.

Skip it if you need to remove established weeds; Scotts Halts Crabgrass & Grassy Weed Preventer also focuses on prevention, not existing weeds.

For established lawns and landscape areas needing spring or fall prevention, this granular formula offers broad listed weed coverage and water-dispersing DG technology. It is not the right choice when the goal is to kill weeds already growing.

#2 · Highest Coverage

2. LebanonTurf Prodiamine .58G

• Weight: 40 lb
• Form: Granule

Best for: Large-area granular coverage.

Why it ranks #2: This 40-pound granular product states coverage of 20,000 square feet and contains 0.58% prodiamine for crabgrass and other listed grassy weeds.

A listed coverage of 20,000 square feet sets LebanonTurf Prodiamine .58G apart for buyers treating a broad lawn or turf area. The granular product uses a BIODAC carrier and contains 0.58% prodiamine for crabgrass and other grassy-weed prevention, with first and follow-up application timing specified.

The 40-pound product covers 20,000 square feet for granular application, giving larger-area users a defined planning figure. Its 0.58% prodiamine targets crabgrass and other grassy weeds listed on the label, while the BIODAC carrier supplies the granular format for lawn turf and grass. Directions call for a first application in early spring followed by a second in late May or early June. Because seeding is restricted for three to four months afterward, coordinate treatment with renovation plans.

Skip it if you plan to seed within three to four months; Scotts Halts Crabgrass & Grassy Weed Preventer instead specifies a wait until after the fourth mowing for newly seeded lawns.

A practical fit for broad lawn or turf areas where a two-step spring schedule and 20,000-square-foot coverage suit the maintenance plan. Avoid it when near-term seeding matters, given the stated three-to-four-month restriction.

#3 · Seasonal Simplicity

3. Scotts Halts Crabgrass Preventer

• Weight: 9.6 lb
• Form: Granule

Best for: Seasonal crabgrass prevention.

Why it ranks #3: The product describes one spring application for season-long crabgrass prevention and a fall application for listed winter weeds.

One spring application of Scotts Halts is specified to prevent crabgrass all season, giving established-lawn owners a straightforward seasonal prevention routine. Its granular formula also has a fall role against winter weeds such as poa annua, henbit, and chickweed, with weather after application not affecting performance.

Apply the granules in spring when the lawn is dry to prevent listed weeds including crabgrass, foxtail, spurge, goosegrass, and oxalis. Fall application addresses winter weeds, and the product information says rain, snow, or freezing weather after application will not affect performance. The seasonal flexibility suits established grass lawns that need either warm-season or winter-weed prevention. Newly seeded lawns have restrictions: wait until after the fourth mowing before use.

Skip it if you need coverage for newly seeded grass before its fourth mowing; The Andersons Barricade Professional-Grade Granular is also for established turf.

Choose this for established grass lawns where a spring crabgrass treatment or fall winter-weed prevention fits the schedule. Its key boundary is establishment: newly seeded lawns must wait until after the fourth mowing before application.

#4

4. Scotts WeedEx Prevent with Halts

• Weight: 10.3 lb
• Form: Bag

Best for: Weather-flexible granular prevention.

Why it ranks #4: This granular preventer is described for spring or fall use, and its listed performance is not affected by rain, snow, or freezing weather.

Scotts WeedEx Prevent with Halts is described as unaffected by rain, snow, or freezing weather after application, helping simplify planning when conditions change. Its granules target germination of listed lawn weeds in early spring or fall, and the product is stated for use on all grass types with an exception noted in its listing.

Early-spring or fall application gives this granular preventer two seasonal windows for crabgrass and other listed weeds. The weather-tolerance statement means rain, snow, or freezing conditions after application will not affect performance, which can reduce concern about changing conditions after treatment. The listing names use on all grass types but also mentions an exception without identifying it in the supplied excerpt; check the label for that detail. Granules can stain cement, stone, metal, clothing, and shoes if not swept or brushed away.

Skip it if you want no surface-stain precautions; Scotts Halts Crabgrass & Grassy Weed Preventer offers listed seasonal prevention without that warning in its supplied details.

Choose it for a lawn-care routine that values spring-or-fall application and stated tolerance to weather after treatment. Take care to sweep granules from hard surfaces and brush them off shoes and clothing to avoid staining.

#5 · Weed-and-Feed Blend

5. The Andersons Barricade Fertilizer

• Weight: 18 lb
• Form: Granule

Best for: Weed prevention with fertilizer.

Why it ranks #5: Its 18-0-4 fertilizer is paired with 0.426% prodiamine, offering prevention and fertilizer in one 18-pound granular product.

An 18-0-4 fertilizer is combined with 0.426% prodiamine in this Andersons Barricade product, enabling a single granular application to pair lawn feeding with weed prevention. It covers 5,000 square feet and uses DG technology, which disperses granules into micro-particles upon watering.

The 18-pound product pairs fertilizer with pre-emergent control, making it a two-purpose option for early-spring or fall lawn care. Its 18-0-4 formulation supplies the fertilizer component, while 0.426% prodiamine prevents listed grass and broadleaf weeds, including crabgrass, poa annua, goosegrass, and henbit. DG technology disperses granules into thousands of micro-particles after watering. The product prevents weeds rather than eliminating existing ones, and the stated coverage is 5,000 square feet.

Skip it if you need coverage above 5,000 square feet; The Andersons Barricade Professional-Grade Granular lists coverage up to 12,880 square feet.

This suits owners of established lawns who want fertilizer and pre-emergent weed prevention in one granular product for spring or fall. Match its 5,000-square-foot coverage to your lawn, and do not expect it to remove existing weeds.

6. Lesco Stonewall 0-0-7

• Weight: 50 lb
• Form: Granule

Best for: Four-month turf-bed prevention.

Why it ranks #6: The 50-pound 0-0-7 granular blend states coverage up to 12,500 square feet and protection for up to four months.

Up to four months of weed protection is the key listed duration for this Lesco 0-0-7 granular product, helping buyers plan a defined prevention window. It covers up to 12,500 square feet and includes potassium, with use listed for turf grass and landscape beds.

The stated 12,500-square-foot coverage helps buyers match the 50-pound bag to a lawn or landscape-bed treatment area. Its 0-0-7 formulation includes potassium, while the listing describes prevention in turf grass and landscape beds for up to four months. Warm-season lawn timing is listed as January through March and September through October. The product is identified as non-returnable and non-refundable, so check the intended application area and schedule carefully before committing to this package.

Skip it if you need a returnable product if plans change; Yard Mastery 0-0-7 Granular Prodiamine lists a 6,000-square-foot application rate.

This fits buyers treating turf or landscape beds who can use the listed coverage and warm-season timing. Its four-month protection window is useful for planning, but the non-returnable listing makes confirming the intended area especially important.

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

#7

7. Yard Mastery Prodiamine 0-0-7

• Form: Granule

Best for: Multi-grass lawn prevention.

Why it ranks #7: This 0.37% prodiamine granular blend includes 0-0-7 fertilizer and lists several grass types, with stated coverage of 6,000 square feet.

Compatibility with seven named grass types makes Yard Mastery 0-0-7 a flexible granular prevention option for lawns with varied turf. Its 0.37% prodiamine targets crabgrass in spring and poa annua in fall, while the listing specifies coverage of 6,000 square feet at three pounds per 1,000 square feet.

A fit for owners of the listed warm- or cool-season grasses who want a granular 0-0-7 product with a stated rate and coverage. Match the 6,000-square-foot coverage to your treatment area before choosing it.

#8

8. Quali-Pro Prodiamine 65 WDG

• Weight: 5 lb
• Form: Granule

Best for: Prodiamine concentrate planners.

Why it ranks #8: The five-pound product is labeled for pre-emergent grass and broadleaf weed control, with spring and fall use noted in its directions.

Quali-Pro Prodiamine 65 WDG combines pre-emergent grass and broadleaf weed control in a five-pound product, giving label-following lawn-care planners a spring-and-fall prevention option. The listing identifies crabgrass control and describes use for season-long prevention, while directing users to the label for rates and safety equipment.

The spring-and-fall application timing makes this a candidate for buyers who plan weed prevention around both seasonal windows. Its stated use covers pre-emergent grass and broadleaf weeds, including crabgrass, rather than treating weeds after emergence. The five-pound quantity and granule form identify the product format, but the supplied details do not provide a coverage figure. Read the label for application rates and protective-equipment recommendations before incorporating it into a lawn-care routine.

Skip it if you need a stated coverage area; The Andersons Barricade Professional-Grade Granular lists coverage up to 12,880 square feet.

This suits buyers comfortable following label instructions for a spring-and-fall prodiamine routine against pre-emergent grass and broadleaf weeds. Consider the missing coverage figure in the supplied details when planning treatment for a known lawn area.

#9

9. Quali-Pro Prodiamine Granules

• Weight: 5 lb
• Form: Granule

Best for: Tank-mix lawn-care planners.

Why it ranks #9: This five-pound prodiamine product lists spring and fall use and names annual bluegrass, henbit, chickweed, and spurge among target weeds.

Quali-Pro Prodiamine 65 WDG is listed as an excellent tank-mix partner with fertilizers and iron solutions, giving combination-treatment planners a specific workflow option. The five-pound product provides pre-emergent grass and broadleaf weed control, with spring and fall use stated for season-long crabgrass control.

The tank-mix compatibility with fertilizers and iron solutions can help buyers coordinate products in a single application workflow, subject to label instructions. Spring and fall use gives this prodiamine herbicide two seasonal prevention windows, and listed targets include poa annua, henbit, knotweed, chickweed, and spurge. Its use sites include turf, landscapes, trees, and golf courses, extending beyond a residential lawn. The supplied details do not provide an area coverage figure, so consult the label for application rates.

A fit for users coordinating prodiamine with fertilizer or iron solutions across turf, landscape, or tree settings. Buyers who need an exact treated-area estimate should account for the missing coverage figure and follow the label for rates.

#10

10. Syngenta Barricade 4FL

• Weight: 4 oz
• Form: Spray

Best for: Liquid concentrate applicators.

Why it ranks #10: The four-ounce spray concentrate is labeled for lawns and established turf, but its format and lack of listed coverage make comparison harder.

Barricade 4FL is a prodiamine pre-emergent concentrate in spray form, giving buyers seeking liquid application an alternative to bagged granules. Its label lists established turfgrasses, lawns, sod nurseries, and ornamental settings among use areas, and the supplied description identifies prevention across flower beds, lawn, and turf.

The four-fluid-ounce concentrate is presented for use across multiple settings, including established turfgrasses, lawns, sod nurseries, and Christmas tree farms. Its spray form fits a liquid-application workflow rather than spreading granules, while prodiamine provides the pre-emergent weed-control role. The description says one application controls pre-germinated weeds in flower beds, lawn, and turf, but it does not give a coverage area or mixing rate in the supplied details. Use label directions to plan application.

Skip it if you need a stated coverage figure before planning; The Andersons Barricade Professional-Grade Granular lists coverage up to 12,880 square feet.

This suits users seeking a liquid prodiamine concentrate for established lawns, turf, or listed landscape settings. The supplied details do not state coverage or a mixing rate, so it is a weaker fit when those figures are essential for planning.
