Details

Benefits and Features:

  • Use in ornamental landscape areas, established lawns and ornamental turf.
  • Can be applied up to 4 weeks later than other pre-emergent Crabgrass preventers.
  • Provides superior control of Crabgrass and many other annual grass and broadleaf weeds.

This weed preventer contains Dimension herbicide, which may be applied up to 4 weeks later than other crabgrass preventers and provides up to 4 months of crabgrass control. This provides pre-emergent control of crabgrass and control or suppression of other listed weeds when applied prior to their germination. In addition, this provides post-emergent control of seedling crabgrass after germination and emergence. Post-emergent control is limited to crabgrass only, but is effective up to 4 weeks after crabgrass has germinated. This generally corresponds to the time when crabgrass seedlings first become visible in the established turfgrass. Do not apply this later than 4 weeks after crabgrass germination. When to apply pre-emergent herbicides and weed preventers will depend on where you live, but in the spring, apply before soil temperatures reach 55 degrees Fahrenheit for optimal crabgrass control.

Florida Applications: Do not exceed 4 applications per year on bermudagrass in central Florida. Do not apply more than 9.2 lb of this product per 1,000 sq. ft. per application and no more than 27.6 lb of this per 1,000 sq. ft. per year (equivalent to 0.5 and 1.5 lb of active ingredient per acre, respectively).

Apply this only to turfgrass species listed on this label. The following turfgrass species are tolerant to this when applied as directed:

Cool-Season Grasses:

Bentgrass, Creeping; Bluegrass, Kentucky; Fescue, Fine; Fescue, Tall; Ryegrass, Perennial

Warm-Season Grasses:

Bahiagrass, Bermudagrass, Buffalograss, Carpetgrass, Centipedegrass, St. Augustinegrass, Zoysiagrass

APPLICATION TIMING

Spring Application

Control of Crabgrass:

Hi-Yield Turf & Ornamental Weed & Grass Stopper Containing Dimension provides pre-emergent control of crabgrass and control or suppression of other listed weeds when applied prior to their germination. In addition, this provides post-emergent control of seedling crabgrass after germination and emergence. Post-emergent control is limited to crabgrass only and is effective up to 4 weeks after germination of crabgrass. This generally corresponds to the time when crabgrass seedlings are at the 3-leaf stage of growth and first become visible in the established turf. This will not control crabgrass at later growth stages when crabgrass plants begin to tiller (spread). Properly timed applications will control existing crabgrass and prevent further emergence of crabgrass seedlings. Do not apply this later than 4 weeks after crabgrass germination.

Control or Suppression of Other Grass and Broadleaf Weeds:

For control or suppression of other grass and broadleaf weeds, this must be applied as a preventative treatment prior to their germination and emergence. Only crabgrass will be controlled with applications made up to 4 weeks after weed germination.

Fall Application

This can also be applied from late summer through early fall (late August through November). When applied in the fall, a sequential or second application of this must be made the following spring to provide season-long control of crabgrass. If this is applied in the fall, do not reseed, overseed or sprig turfgrasses within 12 weeks after application.

    Excellant product

    By Keith on 09/30/2012

    This is the best pre-emergent I have ever used. I have 8000 sq ft of centipede and St. Augustine in central Georgia. My lawn has neighbors on both sides who do no lawn care at all and their dandilions, bahia grass and other weeds come right up to my boundary. As long as I keep this product applied every 3 to 4 months I never get any infestation from either side. I could not be happier and I highly recommend this product to anyone who wants a beautiful, weed free lawn.

    Great, dependable product

    By K on 03/13/2012

    We have used this product on our lawn for several years, and have been very pleased with the results. When it became difficult to find locally, I decided to shop online. Though the price is a good bit higher, the delivery was included, and items shipped right to my front door. Shipping was very fast, and I didn't have to go shopping all around town to find this trusted product.

    Hi-Yield Weed and Grrass Stopper

    By Dr. on 02/24/2012

    Good price and extremely fast shipping... I have used the product before so I expect good results but this is the first time I have purchased from DoMyOwnPestControl. The things I liked best was the fast and free shipping. Will do business with these folks again.

    The BEST pre-emergent herbicide I have used!

    By D. on 03/22/2016

    I purchased this product after using other pre-emergent herbicide granules and coming to the conclusion that none worked until I used this. Due to the "early spring" in the southeast in 2016 I missed the optimal time to apply this before germination. I applied this product anyway and it's doing EXACTLY as it said. It's killing the germinated/growing and even pretty well established fully grown weeds without harming my tall fescue. I WILL be using this product going forward for fall and spring applications.
