The Andersons Barricade Professional-Grade (18 lb) Pre-Emergent
Designed to prevent weeds rather than eliminate existing ones, this granular pre-emergent uses prodiamine to stop both grassy and broadleaf weeds such as crabgrass, poa annua, goosegrass, and henbit. The patented DG Technology (dispersible granule) ensures rapid dissolution with watering, allowing soil-penetrating action that maximizes weed suppression. Suitable for early spring and fall applications, it provides professional-grade control for centipedegrass lawns when applied as directed.
The Andersons Barricade (40 lb) Pre-Emergent
This larger bag option covers up to 12,880 sq ft, delivering the same active ingredient and DG Technology as the smaller bag. It is well-suited for mid-to-large centipede lawns that require longer intervals between applications. The product remains focused on preventive action, helping to avoid germination of crabgrass, poa annua, goosegrass, and other common lawn invaders.
Yard Mastery 0-0-7 Dimension Pre-Emergent (18 lb)
Featuring a 0-0-7 fertilizer base, this pre-emergent uses Dithiopyr to prevent crabgrass and broadleaf weeds before they germinate. It covers up to 6,000 square feet and is aimed at small to medium lawns. The fertilizer blend supports potassium uptake without encouraging excessive shoot growth, making it a practical option for centipedegrass health while keeping weeds at bay.
Yard Mastery 0-0-7 Dimension Pre-Emergent (45 lb)
This larger 45-pound bag expands coverage up to 15,000 square feet, making it suitable for bigger properties or repeated applications. The product uses Dithiopyr to prevent crabgrass and broadleaf weeds before germination and includes a 0-0-7 fertilizer blend that supports turf health and potassium delivery for centipedegrass lawns.
Quali-Pro Prodiamine 65 WDG (5 lbs)
Quali-Pro’s Prodiamine 65 WDG provides broad pre-emergent control for turfgrass and landscape plantings. The product targets a wide range of annual bluegrass, crabgrass, goosegrass, and other weeds listed on the label. It is suitable for established lawns and ornamentals, offering reliable, season-long suppression when applied per label directions. It is an adaptable option for centipedegrass environments seeking preventive weed management.
Quali-Pro Prodiamine, 5 lbs, Yellow Granules

It is suitable for nurse, landscape, turf, trees, and golf course settings, making it a versatile choice for centipede lawns that require consistent preventive protection across different zones. The yellow granules are designed for easy handling and application accuracy.
Buying Guide
Key considerations help determine the best pre-emergent for centipedegrass, balancing weed prevention with turf health and local conditions.
Active Ingredient and Spectrum
Prodiamine and Dithiopyr are common choices for centipede lawns. Prodiamine provides broad protection against many grassy and broadleaf species, while Dithiopyr offers early-season crabgrass suppression and some fertilization benefits. Consider weed pressure in your area and choose a product with an active ingredient matched to target weeds.
Coverage and Application Size
Lawn size dictates bag quantity and coverage efficiency. If you have a smaller yard, 18-pound bags may suffice; larger properties benefit from 40–45 pound bags for fewer refills and better cost-per-square-foot efficiency. Ensure the product label specifies centipede compatibility and timing windows for spring and fall applications.
Soil and Water Interaction
Dispersible granules and soluble formulations differ in how quickly they move into the soil after watering. DG (dispersible granule) technology accelerates soil penetration, enhancing early weed suppression. For centipede lawns that receive irregular rainfall, selecting a formulation with reliable soil uptake improves performance.
Fertility and Turf Health
Some pre-emergents include a fertilizer component (for example, a 0-0-7 blend) that supports turf health without encouraging excessive growth. If your lawn needs a nutrient boost, fertilizers paired with a pre-emergent can simplify maintenance, but avoid products that overly push growth in warm seasons.
Label Instructions and Local Regulations
Always follow product labels concerning application timing, rates, and safety precautions. Local climate and soil conditions influence performance, so consult regional extension services or lawn care professionals if you are unsure about timing or rates for centipedegrass.
Accessibility and Availability
Product availability and retailer access can vary. When evaluating options, consider whether you need a readily available option with clear usage directions, and confirm that it is appropriate for centipede lawns to prevent unintended turf damage.
