The Andersons Barricade Professional-Grade Granular Pre-Emergent (18 lb)
Designed to prevent weeds rather than eradicate existing ones, Barricade uses a professional-grade prodiamine formulation. It targets both grassy and broadleaf species, including crabgrass, poa annua, goosegrass, and henbit. The product employs patented DG Technology (dispersible granules) to dissolve quickly after watering, moving weed control deep into the soil for lasting impact. This is a solid option for early spring and fall applications on smaller lawns or garden plots.
Yard Mastery Dimension Pre-Emergent (18 lb)
This pre-emergent uses Dithiopyr to prevent weeds before germination, offering coverage up to 6,000 square feet. It is suited for small to medium lawns and can be paired with a base fertilizer that supports potassium uptake without stimulating excessive growth. Ideal for curb appeal projects where weed prevention matters without heavy mowing complications.
The Andersons Barricade Professional-Grade (40 lb)
This larger Barricade bag extends coverage to about 12,880 square feet, making it suitable for bigger yards or multi-season planning. It shares the same core benefits as the 18 lb variant: it prevents grassy and broadleaf weeds with prodiamine and uses Dispersible Granule technology for rapid soil entry. Its extended bag size reduces the need for frequent re-purchasing on sizable properties.
Yard Mastery Dimension Pre-Emergent (45 lb)
This 45-pound pack covers up to 15,000 square feet, making it ideal for larger properties or frequent applications to maintain long-term weed prevention. It uses Dithiopyr to stop crabgrass and other broadleaf weeds from germinating, helping maintain a pristine lawn with less maintenance over time. The larger bag also reduces per-use cost for big yards.
Prodiamine 65 Wdg (5 lbs) — Generic Barricade
Quali-Pro’s Prodiamine 65 WDG provides broad pre-emergent weed control for established turf, lawns, sod nurseries, and landscape plantings. It targets a wide list of pests including annual bluegrass, crabgrass, goosegrass, henbit, and many other common lawn weeds. It’s suitable for use across multiple setting types, though users should refer to the product label for exact application rates and compatible turf species.

The included protective gloves support safe handling, making it suitable for both residential gardens and more intensive landscapes. The formulation targets crabgrass, creeping charlie, and other common garden invaders, providing flexible use cases and economic coverage with low usage rates.
Buying Guide
- Weed target and timing: Pre-emergents prevent weed seeds from germinating. Match the product’s active ingredient (e.g., prodiamine, dithiopyr) to the weed profile in your region and the lawn’s season.
- Size and coverage: Bags range from 5 lb to 45+ lb. Choose a size that minimizes reorders for your yard’s total square footage and planned treatment intervals.
- Application method: Some products dissolve via watering, while others may require specific watering schedules. Follow label directions to ensure maximum soil penetration and duration of control.
- Safety and compatibility: Consider pet safety, tolerance for garden beds, and whether the product is suitable for established turf, new sod, or ornamental plantings.
- Seasonality: For intense weed pressure in spring or fall, higher-coverage options (larger bags) can offer better long-term protection and cost efficiency per square foot.
- Regulatory and label compliance: Always review the product label for use restrictions, especially in shared properties or near edible gardens.
- Integrated approach: Pre-emergents work best when combined with proper mowing height, irrigation, and soil health practices to minimize stress on the lawn and reduce weed susceptibility.
