Use as directed to target actively growing weeds while minimizing impact on desired turf or ornamentals.
The Andersons Barricade Professional-Grade
This professional-grade granular pre-emergent helps prevent a broad spectrum of grasses and broadleaf weeds. It does not eradicate existing weeds but adds a strong barrier against germination. The product uses patented DG Technology to dissolve quickly in water, moving active control into the soil for effective long-term results. It’s suitable for landscapes, lawns, and turf systems that want reliable season-long prevention.
Quali-Pro Prodiamine, Pre-Emergent
Quali-Pro Prodiamine provides pre-emergent weed control for grasses and broadleaf species, offering season-long crabgrass management.

The product is commonly used as a tank-mix partner with fertilizers or iron products, broadening its practical application in integrated weed management programs.
Tenacity Turf Herbicide
Tenacity Turf Herbicide offers both pre-emergence and post-emergence control, with systemic activity in turfgrasses. It targets a wide range of common turf weeds, including barnyardgrass, dandelion, crabgrass, and yellow nutsedge, among others. The product acts through absorption as weeds emerge and spread, providing flexible timing for turf management. This makes it a versatile choice for multi-stage weed control in lawns and sports fields.
Buying Guide: Key Purchase Considerations
- Weed stage and timing: Pre-emergents prevent germination, while post-emergents control existing weeds. Evaluate current weed pressures and plan applications around the growing season.
- Target weeds: Consider whether your main issues are crabgrass, broadleaf weeds, or sedges, and select products formulated to address those species.
- Site specificity: Lawn-focused products may differ from landscape, nursery, or golf course formulations. Check labeled use sites to ensure compatibility with your area.
- Mode of action and rotation: Rotate chemistries to minimize weed resistance. Use products with different active ingredients where appropriate.
- Application method and ease: Easy-mix packets or granular formulations can simplify mixing and timing. Professional-grade options may be preferred for larger areas.
- Environmental and safety considerations: Follow label directions for irrigation, rainfall, and protective equipment. Consider impact on non-target plants and waterways.
- Longevity and coverage: Some products offer season-long protection with a single application, while others require reapplication to maintain effectiveness.
