The Andersons Barricade Professional-Grade Pre-Emergent (12,880 sq ft)
The Andersons Barricade is a granular pre-emergent designed to prevent both grassy and broadleaf weeds. It contains 0.48% prodiamine for professional-grade control and uses patented DG Technology for rapid dispersion. It is intended to act before weed seeds germinate and does not eliminate existing weeds. Ideal for early spring and fall applications on large lawns that require robust, long-lasting protection.
The Andersons Barricade 18 lb (5,800 sq ft)
This smaller, granulated Barricade option provides the same professional-grade weed prevention benefits as the larger bag, suitable for mid-size lawns. The formula concentrates on preventing crabgrass and other listed grasses and broadleaf weeds. Its DG Technology ensures quick soil delivery after watering, helping establish soil protection where weeds would germinate.
Scotts Halts Crabgrass & Grassy Weed Preventer
Scotts Halts is a widely used pre-emergent that prevents the germination of crabgrass, foxtail, spurge, moss (in most states), and other listed weeds, depending on seasonal labeling. Best applied in early spring or fall to protect cool-season grasses and more. Its effectiveness relies on proper timing and dry-then-water activation to move active ingredients into the soil before germination occurs.
Yard Mastery Dimension 0-0-7 (45 lb)
This larger Dimension bag covers up to 15,000 sq ft and uses Dithiopyr to prevent crabgrass and broadleaf weeds. The 0-0-7 fertilizer base provides potassium support for turf health without triggering excessive growth. Suitable for bigger lawns or properties with multiple treatment cycles per season, helping maintain weed-free conditions across extended periods.
0-0-7 Granular Prodiamine Pre-Emergent (18 lb)
This Prodiamine-based pre-emergent is designed for broad weed suppression, including crabgrass and Poa annua. The 18-pound bag covers about 6,000 sq ft at the recommended rate. It is compatible with a variety of grass types, making it a flexible option for diverse lawns and those seeking compatibility with other turf management practices.
Quali-Pro Prodiamine Pre-Emergent 5 lb
Quali-Pro Prodiamine 65 WDG offers flexible pre-emergent application for spring and fall, providing season-long crabgrass control. The 5-pound bottle is suitable for smaller areas, nurse plots, or as a preventive addition to existing lawn care programs. It pairs well with fertilizers or iron solutions as part of broader lawn maintenance strategies.
Buying Guide: Key Purchase Considerations
- Coverage versus lawn size: Choose bags that align with your yard’s total square footage and treatability. Larger bags can reduce the frequency of purchases but must be stored properly to maintain effectiveness.
- Active ingredient and weed spectrum: Prodiamine and Dithiopyr target crabgrass and other germinating weeds; confirm local weed pressure and labeling for your region.
- Soil activation and rainfall: Some products rely on irrigation or rainfall to move the active ingredient into the soil. Check application timing relative to forecasted rain.
- Seasonal timing: Pre-emergents are most effective when weeds are about to germinate (spring and/or fall). Align application with your local climate and lawn type.
- Grass compatibility: Ensure the product is labeled for your grass species and irrigation plan. Some formulas work across many grass types, while others are more specific.
- Storage and handling: Store in a cool, dry place and follow label directions for safe handling to maintain product integrity and user safety.
- Tank mixing and legibility: If combining with other lawn care products, use compatible formulations and follow recommended mixing guidelines to avoid phytotoxicity.
- Cost per square foot: Compare price per 1,000 sq ft to gauge long-term cost-effectiveness, especially for larger properties.
- Application timing for weather: Avoid applying before heavy rainfall or when soil is saturated to prevent runoff and uneven distribution.
- Regulatory and safety considerations: Adhere to local guidelines on pesticide use and protect pets and children during and after application as advised.
Overall, select a product whose coverage fits your lawn size, whose active ingredient aligns with your weed pressure, and whose application timing works with your regional climate. For larger properties, higher coverage bags paired with robust formulations like Barricade or Dimension can offer durable protection. For smaller spaces, lighter bags with precise application may be more practical, particularly when integrating with ongoing lawn maintenance programs.
