The Andersons Barricade – 5,800 Sq Ft Guards Against Weeds
The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control is designed to prevent weeds rather than eradicate existing ones. It targets both grassy and broadleaf species, including crabgrass, poa annua, goosegrass, and henbit. The product contains 0.48% prodiamine for professional-grade weed control and uses patented DG Technology (dispersible granule) to dissolve quickly with watering, delivering weed control directly into the soil for maximum impact. Coverage and application timing suit early spring and fall programs well.
The Andersons Barricade – Larger 12,880 Sq Ft Pack
This larger Barricade formulation provides the same preventive benefits as the smaller bag, designed for expansive lawns. It prevents a broad spectrum of weeds and relies on 0.48% prodiamine to deliver long-lasting protection. The DG Technology ensures rapid dissolution after watering, helping the active ingredient reach the soil promptly for effective early-season and fall weed control. Ideal for bigger properties or multiple-season applications, maintaining consistency across lawn zones.
Yard Mastery Dimension Pre-Emergent – 18 lb

The 18 lb bag covers up to 6,000 square feet, making it suitable for small to medium lawns. The fertilizer base supports potassium uptake without pushing lawn growth, aligning with maintenance programs that prioritize weed prevention while keeping turf density steady.
0-0-7 Prodiamine Pre-Emergent – 18 Lbs
This 0-0-7 granular pre-emergent uses prodiamine to prevent a broad range of weeds, including crabgrass and poa annua. The 18 lb package covers about 6,000 square feet at the typical application rate, making it a practical option for medium-sized lawns. It’s described as versatile for various grass types and supports long-term weed prevention alongside standard lawn care routines.
0-0-7 Prodiamine – 45 Lbs for Bigger Areas
The larger 45-pound bag provides a robust option for sizeable lawns or professional applications. Featuring prodiamine, this granular pre-emergent aims to prevent a broad range of weeds, including crabgrass and poa annua. The extended coverage makes it suitable for ongoing lawn maintenance plans or multi-zone properties, delivering long-term weed prevention with fewer reapplications.
DOW Snapshot 2.5 TG – Long-Lasting Control
DOW Snapshot 2.5 TG Granular Pre-emergent Herbicide is positioned as offering extended control, with up to 6-8 months of weed suppression for a large list of broadleaf and grassy weeds. Application rates range from 2.3 to 4.6 pounds per 1,000 square feet, providing flexibility for different turf types and local conditions. This option is suitable for those seeking a longer window between applications and broad-spectrum weed prevention.
Buying Guide: Key Purchase Considerations
- Coverage and lawn size: Match bag size to your total area and target zones. Larger bags reduce reapplication frequency for big properties.
- Active ingredients: Prodiamine provides broad preventative action; Dithiopyr adds early-season preventive strength. Consider a mix that aligns with your weed history.
- Turf compatibility: Verify compatibility with your grass type (Bermuda, St. Augustine, Zoysia, Fescue, etc.). Some formulas are designed to work across multiple species.
- Timing and seasonality: Early spring and fall applications are common; plan around your local climate and weed pressure timeline.
- Cancellation of existing weeds: Note that most granular pre-emergents prevent new germination but do not eliminate established weeds.
- Technology and dissolution: Dispersible granules and rapid soil delivery can improve efficacy after watering.
- Storage and handling: Store in a cool, dry place and follow label instructions for application rates and safety.
When choosing a granular pre-emergent, consider your lawn size, typical weed pressure, and whether you prefer a product with a longer control window or one that integrates easily into an existing fertilization schedule. The products listed above span a range of coverage, active ingredients, and lawn sizes to help homeowners and professionals tailor their weed prevention strategy to their unique turf conditions.
