The Andersons Barricade 5,800 Sq Ft — Prodiamine Granular
The Andersons Barricade is designed to prevent weed germination rather than remove existing weeds. It targets grassy and broadleaf species, including crabgrass and poa annua. The product contains 0.48% prodiamine for professional-grade control. Its patented dispersible granule (DG) technology helps granules dissolve quickly after watering, moving the active ingredient into the soil for maximum impact. Suitable for application in early spring and fall, it emphasizes prevention over eradication, making timely applications essential for best results.
The Andersons Barricade 12,880 Sq Ft — Prodiamine Granular
This larger Barricade formulation expands coverage to about 12,880 square feet, still using prodiamine at 0.48% for robust pre-emergent action. The product maintains the same DG Technology for rapid soil movement of the active ingredient when watered. It remains focused on preventing a broad spectrum of weeds in early spring and fall, offering a practical option for homeowners with larger lawns or multi-zone properties who want a single product to handle bigger areas.
Yard Mastery 0-0-7 Dimension 18 lb — Up To 6,000 Sq Ft
This Dimension pre-emergent uses Dithiopyr to suppress crabgrass and other weeds before they appear. It covers up to 6,000 square feet and includes a 0-0-7 fertilizer base to support potassium uptake without promoting excessive growth. This makes it suitable for small to medium lawns seeking a single product that both protects against weed germination and contributes some turf nutrition.
Prodiamine 65 Wdg 5 Lbs — Generic Barricade
Quali-Pro’s Prodiamine 65 WDG provides a broad-spectrum pre-emergent option for grass and broadleaf weed control. It targets a wide range of listed pests, including Poa annua, crabgrass, goosegrass, and henbit, among others. Suitable for established lawns, sod nurseries, and ornamentals, this product is a flexible choice for homeowners who want a strong pre-emergent that can be applied across multiple landscape settings. Always refer to the label for exact pests and use instructions.
Yard Mastery 45 Lb — Dimension Pre-Emergent, Large Coverage
Designed for larger lawns or properties with extended weed-prevention needs, this Dimension pre-emergent offers up to 15,000 square feet of coverage. The formula uses Dithiopyr with a 0-0-7 fertilizer blend that adds potassium for turf health without encouraging rapid growth. It is well-suited for homeowners planning multiple seasonal applications to sustain a weed-free lawn across expansive areas.
Buying Guide: Key Purchase Considerations
- Weed targets: Identify whether you need broadleaf and grassy weed prevention or primarily crabgrass prevention. Prodiamine-based formulations generally offer broad-spectrum pre-emergence, while Dithiopyr targets crabgrass specifically in early germination.
- Lawn size and coverage: Choose a product with sufficient coverage for your total lawn area. Larger bags or multiple-bag options reduce the frequency of purchases.
- Timing: Pre-emergents must be applied before weed seeds germinate, typically in early spring and/or fall. Read label timing recommendations to maximize effectiveness for your region.
- Soil and weather considerations: Some products dissolve quickly with watering, while others may require moisture to activate. Consider recent rainfall and irrigation schedules when planning applications.
- Nutrient balance: If choosing a fertilizer-based pre-emergent (0-0-7 or similar), ensure it aligns with your turf’s nutrient needs to avoid over-fertilizing or under-fertilizing.
- Safety and application method: Granular formulations are common, but read safety data and follow protective equipment guidance. Some products may be suited for larger landscapes or professional use.
- Longevity and reapplication: Some pre-emergents offer longer-lasting protection, reducing the need for frequent reapplication, while others may require more frequent intervals, particularly in regions with heavy rainfall.
- Compatibility: If you are overseeding or planting new sod, check label restrictions since some pre-emergents can interfere with seed germination or establishment.
