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.

    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.

    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.

    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.

Q
Is Hi-Yield Weed and Grass Stopper with Dimension Herbicide effective on Virginia buttonweed?
A
Hi-Yield Weed and Grass Stopper with Dimension Herbicide is not labeled for Virginia Buttonweed and we are not sure how well it work for this weed. We recommend you choose a product that lists buttonweed on the product label for best results such as Fertilome Weed Out Lawn Weed Killer with Trimec or Image 70DG. Virginia Buttonweed can be one of the most stubborn weeds to control and multiple applications of an herbicide may be needed.

Q
I'm looking for a crabgrass pre-emergent for my new lawn.

I have a new lawn that I had seeded last year and the grass is growing well. I live on Long Island New York. Previously I had very bad crabgrass problem. I am hoping to stop the crabgrass this year. Can you please recommend a pre-emergent for my lawn and when I should apply it?

A
Almost every pre-emergent can only be used on well established lawns only. Using pre-emergents on lawns that are not well established could lead to unfavorable results. If you feel your lawn is well established you can use Hi Yield Turf and Ornamental with Dimension to control crabgrass both pre-emergently and post-emergently (for up to 4 weeks).

Q
Will product prevent germination of bermuda grass seed

Established st augustine/ Tiff 419 lawn

A
Hi-Yield Weed and Grass Stopper with Dimension Herbicide is labeled for use on both St augustine and bermuda grass so it will not work to stop the germination of Bemuda.
Unfortunately Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the Bermuda as well.  In your situation it is recommended to spot treat the Bermuda with Round Up and kill it directly, and then replant St. Augustine in those areas. We do carry some professional round up products:  http://www.domyownpestcontrol.com/nonselective-herbicides-c-188_408.html

Q
When should I apply Hi-Yield Weed and Grass Stopper to control annual blue grass in a St. Augustine & Centipede lawn? I live in in the northern part of SC.
A

Most pre-emergent applications can be applied in early fall and spring. Please click on the link below for the contact information for your local county extension office for specific times for application. I have also included the number to the manufacturer of Hi-Yield Weed and Grass Stopper for more information on applying this product to your turfgrass. Some types of St. Augustine can be very sensitive to products.
