Hi-Yield (31134) Grass Killer Postemergence
This selective post-emergent herbicide targets and kills unwanted grass growth. It is designed to be applied around vegetables, gardens, trees, shrubs and ornamentals with a focus on stopping weed grass growth within a short timeframe. Best for small to medium lawns that require rapid weed suppression while maintaining nearby ornamentals.
Best for: Homeowners needing a quick, targeted response to grassy weeds in bermudagrass lawns. Why selected: clear selectivity and fast growth suppression. Caution: verify nearby ornamentals tolerate the treatment as per label directions.
Pro Crabgrass & Grassy Weed Killer – Quinclorac
This product emphasizes high concentration and quick action. It offers residual control to reduce weed reemergence and is suitable for lawns, gardens, and landscapes seeking broad suppression of crabgrass and other grassy weeds. Best for larger areas where residual weed control matters and quick visible results are desired.
Best for: Larger bermuda lawns or commercial spaces with ongoing crabgrass challenges. Why selected: high concentration and residual control. Caution: effective labeling is essential to avoid unintended effects on desirable grasses and ornamentals.
Monterey Remuda Weed & Grass Killer
Remuda is a broad-spectrum post-emergence herbicide designed to kill a wide range of grasses and broadleaf weeds. It is described as non-selective and concentrated, containing 41% glyphosate with surfactant. It is best used where active growth is present and can be applied around flowerbeds, trees and shrubs to manage weeds without extensive turf disturbance.
Best for: Bermudagrass areas needing broad weed kill during active growth. Why selected: broad-spectrum capability and concentrated form. Caution: not selective; may injure desirable turf if misapplied or used in sensitive areas.
Atticus Azion XP MSM Turf Herbicide (8 oz)
Azion XP delivers powerful selective weed control thanks to 60% metsulfuron-methyl, the same active ingredient used in Manor Herbicide. It targets weeds in bermudagrass and St. Augustine grass, including difficult grassy and broadleaf weeds. Best for: Bermudagrass or St. Augustine lawns needing selective postemergence control. Why selected: strong selective activity and a label-focused weed list. Caution: do not apply to other turfgrass species to avoid plant injury.
Atticus Azion XP MSM Turf Herbicide (16 oz)
This 16-ounce size mirrors the 8-ounce formulation with the same 60% metsulfuron-methyl content. It is intended for selective postemergence weed control in bermudagrass and St. Augustine grass. Best for: Larger or multiple-area applications where efficient dilution is beneficial. Why selected: scalable application while maintaining selective weed control. Caution: follow label directions closely to avoid turf injury on sensitive areas.
Buying Guide
Key considerations to guide your purchase and application strategy:
- Weed spectrum: Choose a product that targets the specific weeds in your lawn, such as crabgrass or broadleaf species, and verify turf compatibility.
- Turf type and sensitivity: Bermudagrass and St. Augustine grass have different tolerances. Select products labeled for bermudagrass and follow dosage instructions to avoid injury.
- Postemergence timing: Apply when weeds are actively growing for better absorption and efficacy. Avoid application during extreme heat or drought stress.
- Concentration and coverage: Higher concentration often means broader residual effects but requires careful handling. Check label-recommended application rates for your lawn size.
- Safety and ornamentals: If you have nearby ornamentals, trees, or garden beds, prioritize products noted as safe for surrounding plants or use protective buffer practices.
Practical buying considerations
- Non-selective vs selective: Non-selective products kill most plants and are best for non-turf areas or patch cleanup, while selective products target specific weeds in bermudagrass.
- Weather and timing: Plan for calm days with mild temperatures to minimize drift and improve uptake. Postemergence products work best during active weed growth.
- Storage and shelf life: Store away from extreme temperatures and direct sunlight to preserve efficacy; note any shelf-life guidance from the manufacturer.
