Choosing the right pre-emergent involves understanding the weed spectrum, coverage area, and compatibility with your fertilizer plan. The products below are analyzed for soil activity, dispersal technology, and ease of watering-in to maximize effectiveness without stressing established turf.
The Andersons Barricade 5,800 sq ft
The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control is designed to prevent a wide range of grasses and broadleaf weeds, including crabgrass and poa annua. It uses 0.48% prodiamine for professional-grade protection and employs patented DG Technology, a dispersible granule that dissolves rapidly upon watering. This ensures the active ingredient moves directly into the soil for maximum effect, making it suitable for early spring or fall applications in smaller lawns. It does not treat existing weeds, only preventive control.

The 0-0-7 fertilizer base assists potassium uptake, supporting turf health without promoting rapid growth. Its coverage reaches up to 6,000 square feet, making it a practical option for small to medium lawns. The formulation provides reliable pre-emergent action, helping to limit weed establishment while maintaining lawn integrity.
The Andersons Barricade 12,880 sq ft
This Barricade version covers a larger area (12,880 sq ft) and uses the same 0.48% prodiamine active ingredient with DG Technology for rapid soil dispersion. It provides professional-grade pre-emergent protection by creating a robust barrier against grassy and broadleaf weeds, including crabgrass, poa annua, and goosegrass. It is designed to prevent weed germination in larger landscapes while remaining compatible with standard lawn care routines.
Prodiamine 65 WDG (5 lbs)

Buying Guide: Key Purchase Considerations
When selecting a pre-emergent, consider the following:
- Weed spectrum: Different formulations target various grasses and broadleaf weeds. Check the product label for the specific weeds controlled.
- Coverage area: Match the product’s square footage to your lawn size. Larger yards may require bag sizes like 40 lb or multiple bags for complete coverage.
- Turf compatibility: Some formulas are suitable for established lawns, sod nurseries, or landscape plantings. Ensure compatibility with your turf type and nearby ornamentals.
- Watering and activation: Most pre-emergents require watering to activate and move into the soil. Patience and proper irrigation timing improve results.
- Combination products: Fertilizer-based pre-emergents offer both weed prevention and turf nutrition, but verify that the nutrient load aligns with your lawn care plan.
- Seasonality: Apply in early spring and/or fall for best results depending on local climate and target weeds. Follow label timing guidelines.
For optimal results, integrate pre-emergents with a broader lawn-care schedule that includes proper mowing height, irrigation management, and selective post-emergent treatments if weed pressure arises. Always read the label for application rates, timing, and safety precautions before use.
