Barricade 4FL Pre-Emergent Weed Preventer
Syngenta Barricade 4FL is a long-lasting pre-emergent herbicide designed to prevent weed development before they germinate. It helps reduce common lawn weeds such as crabgrass, chickweed, oxalis, goosegrass, Poa annua, and spurge when used as directed. For best results, apply before soil temperatures reach 55 F for a three-day average in winter or spring, and after temperatures drop below 50 F in fall but before the ground freezes. Proper timing maximizes season-long protection and minimizes weed pressure throughout the growing season.
One well-timed application can provide season-long prevention when used as directed. Barricade is suitable for residential turf, landscape ornamentals, and trees and shrubs. Its broad-spectrum approach targets numerous weed species, with effectiveness varying by turf type and application timing.

Buying Guide
When selecting a pre-emergent to combat grass burrs, consider weed targets, turf type, climate, and application logistics. The following factors help compare options and choose the best fit for your lawn:
- Weed targets and spectrum: Some products concentrate on crabgrass and annual grasses, while others offer broader control that includes several broadleaf species. Review the label to confirm which weeds are prevented.
- Turf compatibility: Check whether the product is labeled for your grass type (cool-season, warm-season, or ornamentals) to avoid turf injury and ensure effective results.
- Active ingredients and formulations: Prodiamine-based products (like Barricade and Prodiamine 65 WDG) are common, while others use granular or liquid formulations with different activation needs. Follow label directions for mixing, spreading, and irrigation.
- Timing and soil temperature: Timing is critical. Many pre-emergents are most effective when soil temperatures are in a specific range for several days. Spring and fall timing varies by product and climate.
- Application method and coverage: Granular vs liquid concentrates affect equipment needs (spreader compatibility) and coverage consistency. Ensure you have the right tool and follow rate guidelines.
- Seasonal strategy: Some products offer season-long protection with a single application, while others require reapplication to maintain control across different seasons.
- Fertilizer integration: Some products include fertilizer or promote quicker green-up. If you’re applying multiple products, ensure compatibility and avoid over-fertilization.
- Safety and re-entry: Read the label for drying times, pet safety, and re-entry intervals, especially for families with children and pets.
- Label compliance and updates: Formulations and labels may change. Always base purchases on the current label and local extension recommendations.
