    Excellent Product for Preventing Crabgrass Emergence

    By Chad on 05/20/2013

    Verified Purchase

    I purchased this product a few weeks ago in half gallon jug. My yard is about 18,000 square feet of grass. Had a big problem with crabgrass infestation every year. Through research, I discovered that crabgrass seeds germinate in the spring when soil temps reach about 50 degrees. I monitored soil temps via a local university agriculture website. When soil temps at 2 inches deep got near 50 degrees I applied Dimension. I measured out 3000 square foot areas and applied the product using a pump sprayer. I put about 5 teaspoons in a gallon of water. One gallon of water seemed to be the right amount to cover the 3000 square foot area. Turned on my sprinklers and made sure each area got a 1/2 inch of watering. I placed a 9x13 pan in each area and watered until the pan had 1/2 inch in it. Days later my crab grass areas are bare with beautiful green desirable grass surrounding. I plan to fertilize over Memorial Day weekend in order to promote desirable grass to spread to the bare areas. Remember this product prevents seed germination, so you must apply before crabgrass emerges and not after.

    Don't Buy it

    It hasn't yet prevented anything and didn't kill anything that was there...........don't buy this product.

    Expert ResponseExpert response:
    This product does not kill anything that is currently there, because it is a pre-emergent.  It will only prevent weed seeds from germinating.  If something appears after using this product, then it was not applied soon enough and the weeds already germinated.

    Dimension 2EW Herbicide

    By C.r. on 02/20/2011

    Verified Purchase

    Dimension is an excellent pre-emergent herbicide. We have had no weeds since putting it down. I would recommend it for farmers that need ultimate weed control for roads, driveways, or other ultimate control areas. DoMyOwnPestControl.com has the best price on the net. I have found them to be excellent and the products you see are actually the products that arrive.

    Works great but don't save any for next year

    By Randy on 03/08/2015

    Verified Purchase

    Pretty aggravated today. Used this last year and it worked great. I had 3/4 gallon left over and tried to use it this year. Something falls out of suspension, likely the active ingredient but I don't know. And, there is no amount of shaking that will mix it back up. I used it anyway having to stop every fifty feet to clean the filter in the tank. So, if you buy it use it.

    Crabgrass control

    By Jack on 05/28/2012

    Verified Purchase

    I have wrestled with a vigorous crabgrass invasion and 'Dimension' has exceeded all expectations in controlling this. I estimate a 98% eradication of any new crabgrass seedlings and am left with the best looking bare areas I could wish for. I believe two key steps made this so successful. The first is I made split applications with 8 oz/25 gal tank of water applied in early April (Mid-west), which was followed with a 0.3 inch rainfall. A second application four weeks later was followed with 1.1 inches of rain. When I use Dimension again next year I will dilute even further so more water is used in each application. In total I have treated approx two acres and gained excellent control of crabgrass. Roundup has taken care of those mechanical escapes.

Questions & Answers

Have a question about this product?
  
Q
Ratio product to water when using Dimension.
A

Herbicides are a lot different than other concentrated products and can be hard to understand at first. The application rate depends on the the type of turf you have and how quickly you apply the product.  You will need to read the product label to determine the correct usage rate for your needs (you did not give us any information about the type of lawn, region or application program you will be using so we cannot give you exact rates). The amount of water used to apply Dimension herbicide is not critical, but should be sufficient for uniform coverage of the target area. Calibrate by determining the volume of water required to treat 1,000 square feet. Use this calibration volume to determine the amount of water and Dimension herbicide needed to treat the target area (see the following calibration example). Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator.

Steps in Calibration:
1. Mark an area of 1,000 square feet (i.e. 20 by 50 feet or 25 by 40 feet).
2. Place the sprayer on a level surface and add water noting the final level of water in the spray tank.
3. Spray the marked area with a sufficient volume of water to provide uniform coverage. Refill the sprayer to the same level as before measuring the amount of water added. The measured water added to the sprayer is the volume needed to cover 1,000 square feet.
4. Determine the application rate (0.073- .55 fl. oz./1,000 sq. ft.) for Dimension from the Recommendations section of this label.
5. To each volume of water used as measured in step 3, add the amount of Dimension as determined in step 4.

Example: If the sprayer uses 1 gallons of water to cover 1,000 square feet and the desired application rate of Dimension is .55 fluid oz./1,000 square feet, then you would add .55 fluid ounces of Dimension to every 1 gallon of water to be used."

Q
Can this product be used with Ortho Dial n Spray and at what dial setting per gallon of water?

How many oz., tsp, or tbls per gallon of water? This is to treat annual bluegrass and crabgrass. Thanks
A
You can use a hose end sprayer to apply this product, but we are not familiar with the Ortho model so we do not know what specifics to give you.  As far as application rates, we wish it was that easy.  Bluegrass and Crabgrass require slightly different treatments and also depend on where you live and what grass you have currently that you are trying keep them out of, which you did not state.  Also, herbicides do not give a water amount.  They only tell you how much of the product to apply over 1000 square feet.  The amount of water is dependent on how ever much water it takes for you to walk 1000 square feet.  Whether you place the amount of product per 1000 square feet in a gallon of water or 10 gallons of water, it does not matter, just as long as that amount of product is distributed over the 1000 square feet.  Since you are treating two different types of grasses, we recommend calling the manufacturer since they are the experts on their own product and could probably give you a more definitive answer than we can.  They should also be able to better help you with the settings on your hose end sprayer.  The manufacturer is Dow Agro and you can reach them at 1-317-337-3000.

Q
Once applied, how long after applying Dimension can we leave the pets outside on the lawn?
A
As soon as Dimension 2EW has dried on the lawn it is safe to allow pets back on the lawn.  This depends on how hot it is, but most of the time 1 hour is plenty long enough for the solution to dry.

Q
What is the ground coverage for the 1/2 gallon for use on crabgrass?
A
You will use .33 - .73 of an ounce of Dimension 2EW per 1,000 sq ft. The exact usage rate will depend on your location and the application program you choose. Please refer to pages 4-6 of the product label to find the exact usage rate for your needs.
