Syngenta’s Barricade 4FL is a liquid pre-emergent herbicide that controls the development of over 30 species of turf weeds including crabgrass, chickweed, goosegrass, and Poa annua. It works best when applied before soil temperatures reach 55°F in spring or after they drop below 50°F in fall.

Mesotrione acts quickly upon application but may take several weeks for full effect. Activation requires watering if rainfall is insufficient within 10 days. It is safe for many turf types, including dormant Bermuda grass, but users should avoid applying to certain sensitive grasses.

Buying Guide for Pre-Emergent Products for Bermuda Grass
Choosing the right pre-emergent herbicide for Bermuda grass involves considering multiple factors to ensure effective weed control without harming your turf:
1. Target Weed Spectrum
Identify the prevalent weed species in your lawn. Some products focus on crabgrass and grassy weeds, while others cover broadleaf weeds like clover, chickweed, and dandelion. Broad-spectrum options provide versatile control but verify compatibility with Bermuda grass.
2. Application Timing and Frequency
Most pre-emergents perform best when applied before weed seeds germinate, typically in early spring or fall depending on the weed and climate. Some product formulas allow post-emergent applications for existing weeds, offering more flexibility.
3. Formulation Type
Granular formulations are easy to spread and suitable for many lawn types, while liquid concentrates offer precise control and rapid absorption but require mixing and spraying equipment. Choose based on convenience, coverage area, and personal preference.
4. Turfgrass Safety and Compatibility
Ensure the herbicide is safe for Bermuda grass. Some products may restrict use on specific turf types. Products like mesotrione are safe on dormant Bermuda grass but may harm other grass species.
5. Longevity and Residual Control
Look for products offering season-long control with a single application to reduce labor and minimize chemical use. Residual duration impacts how often reapplication may be necessary.
6. Environmental and Application Restrictions
Check product labels for restrictions related to weather conditions, runoff prevention, and turf use cases such as golf courses or ornamentals. Proper application ensures environmental safety and effective control.
By balancing these considerations, you can select a pre-emergent weed control product that optimizes your Bermuda grass lawn’s health and appearance throughout the growing season.
