The Andersons Barricade Professional-Grade Granular Pre-Emergent
The Andersons Barricade uses prodiamine to prevent a broad range of grassy and broadleaf weeds, including crabgrass. This professional-grade formula is designed for early spring and fall applications, aligning with typical crabgrass germination windows. Its patented DG Technology (dispersible granules) ensures rapid dissolution after watering, moving weed protection into the soil for strong, long-lasting results. It does not eliminate existing weeds, so timing is key for prevention. This product is suitable for larger lawns, offering coverage up to 5,800 square feet per bag.
Key considerations:
– Effective prevention of crabgrass and other common annual weeds
– Requires watering to activate and move into the soil
– Best used as a preventative measure in early spring and fall

Buying Guide: Key Purchase Considerations And Comparisons
When selecting a crabgrass pre-emergent, consider your lawn type, climate, and weed pressure. Here are essential factors to evaluate:
- Active ingredient: Prodiamine and dithiopyr are common options, each with different weed spectrums and activation requirements. Prodiamine typically requires soil incorporation, while dithiopyr provides preventive action with seasonal flexibility.
- Coverage and bag size: Larger lawns benefit from multi-bag products like the 18 lb offerings, which cover up to 5,800–6,000 square feet per bag. Calculate your lawn area to avoid runout.
- Timing and activation: Most pre-emergents should be applied before crabgrass germination, usually in early spring and/or fall, depending on your region. Proper watering after application enhances soil movement of the product.
- Damage risk and compatibility: Some products may interact with reseeding schedules or fertilizer programs. Read label instructions to ensure compatibility with your lawn care plan and seasonal seeding.
- Broad weed control: If you want protection beyond crabgrass, choose formulations that list Poa annua, goosegrass, chickweed, and other frequent weeds on the label.
- Ease of use: Granular products with dispersible granules simplify application for many homeowners, reducing the need for specialized equipment.
For different lawn goals, here are quick contrasts:
- Best overall breadth: Prodiamine-based products often provide broad-reaching prevention across multiple weed species and turf types.
- Best for spring and fall: Products marketed for dual-season prevention help suppress both summer and winter weeds when applied at appropriate times.
- Best for large lawns: Higher coverage per bag reduces the number of bags and application time, beneficial for larger properties.
- Best for ease of use: Ready-to-apply granular formulas with clear activation steps are friendly for DIY homeowners.
Always follow the product label for exact application rates, timing windows, and safety precautions. If you’re unsure about compatibility with your specific grass type or seeding plans, consult a local extension service or lawn care professional for tailored guidance.
