Hi-Yield Turf & Ornamental Weed & Grass Stopper is a powerful pre-emergent herbicide designed to prevent the emergence of crabgrass, annual grasses, and listed broadleaf weeds before they sprout. Powered by Dimension® (dithiopyr), it also provides early post-emergent crabgrass control, making it ideal for homeowners who may apply slightly later in the season. Suitable for both warm- and cool-season grasses, this granular formula protects lawns, landscape beds, and ornamental turf for up to four months, helping maintain a clean, weed‑free landscape with minimal effort.
Key Features
• Pre-emergent and early post-emergent crabgrass control
• Controls and suppresses many annual grassy and broadleaf weeds
• Long-lasting residual protection (up to 3–4 months)
• Can be applied later in the season than most competitors
Where to Use
Designed for established lawns, ornamental turf, landscape beds, and other non-crop ornamental areas. Works on both warm-season and cool-season turf varieties.
Weeds Controlled
Prevents crabgrass, barley, goosegrass, bittercress, and many other listed grassy and broadleaf weeds before they germinate. Also provides early post-emergent control of young crabgrass seedlings.
How to Apply
Apply uniformly using a broadcast or drop spreader. Water lightly afterward to activate the herbicide barrier. Avoid mowing immediately before or after application for best performance.
Application Timing
Apply in early spring or fall before weed germination. May be applied up to 4 weeks later than traditional pre-emergent crabgrass products while still ensuring effective control.
Coverage
Coverage varies by bag size—typical rates treat between 3,500 and 15,000 sq. ft., depending on turf type and application rate.
Active Ingredient
Contains Dithiopyr (Dimension®) 0.125%, a selective pre-emergent herbicide with early post-emergent crabgrass capability.
Safety Information
Safe for pets and people once the product has been watered in and the treated area is dry. Follow all label directions for safe handling and proper application.
Note:
- Always follow label instructions carefully for safe and effective use.
- Store in a cool, dry, and out-of-reach location.
- Avoid applying to newly seeded areas or areas where you plan to plant.
