It targets grassy and broadleaf species, including crabgrass and Poa annua. The product contains 0.48% prodiamine for professional-grade protection and uses patented DG Technology to ensure rapid dissolution upon watering, moving active control into the soil for maximal effect. This granule format suits early spring and fall applications aimed at long-lasting weed prevention.
Syngenta Barricade 4FL Herbicide
Syngenta Barricade 4FL is a long-lasting pre-emergent herbicide that prevents weed development before germination. It works across lawns, turf, ornamentals, and more, with guidance to apply before soil temperatures reach 55°F for winter/spring and after 50°F in the fall but before freezing. A single application can provide season-long protection against 30+ weed species, including crabgrass, Poa annua, goosegrass, and spurge. The formulation targets germinating seeds and is appropriate for broader landscape use with proper labeling.

Yard Mastery Dimension 0-0-7 is a granular pre-emergent using Dithiopyr to stop weeds before they germinate. It covers up to 6,000 square feet and is suitable for small to medium lawns. The 0-0-7 formula supports potassium uptake without pushing excessive growth, aiming to maintain turf health while reducing weed establishment. This product is often used as a dependable foundation for seasonal weed prevention in residential yards.

This 0-0-7 Granular Prodiamine Pre-Emergent Herbicide prevents a range of weeds, notably crabgrass and Poa annua, with an emphasis on broad-spectrum lawn weed control.

It aims to create a barrier in the soil, stopping weed emergence through targeted timing in spring and fall applications.

With a Dithiopyr-based formula, it targets crabgrass and a broad range of broadleaf weeds, making it suitable for larger properties or repeated application cycles. The larger bag size is designed for extended seasonal programs, helping to simplify weed prevention across extensive lawns and garden beds.
Buying Guide
- Active ingredient and weed target: Prodiamine-based products excel at broad-probe prevention, while Dithiopyr provides early-season control alongside pre-emergent protection. Match the product to your most problematic weeds (crabgrass, Poa annua, goosegrass, etc.).
- Application window: Many pre-emergents require timing with soil temperatures. Plan applications in early spring and fall, following label guidance for temperatures and timing to maximize efficacy.
- Coverage and bag size: For small lawns, 18–36 lb bags may suffice, while larger properties benefit from 45–120 lb bags or multi-bag plans to minimize reapplication efforts.
- Granular vs. liquid: Granular formulations are easier to apply with spreaders and tend to deliver longer residual protection in soil. Liquid options may offer quicker dissolution but require precise calibration and frequent reapplication.
- Tomorrows needs vs. existing weeds: Pre-emergents do not eliminate established weeds. If you already have a weed problem, combine with a post-emergent or mechanical weed control strategy, following label recommendations.
- Turf compatibility: Ensure the product is labeled for your grass type and garden bed plants. Some formulas are designed for lawns, others for ornamentals, citrus, or fruit trees—check the label for site-specific use.
- Safety and storage: Store in a dry, shaded area and follow safety guidelines on the product label. Wear appropriate PPE during application and keep pets and children away until the product has settled.
