    5 of 5 Stars  Excellent Product for Preventing Crabgrass Emergence
    By Chad in Minot, ND on May 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.

    By C.r. in Stevinson, CA on February 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.

    5 of 5 Stars  Crabgrass control
    By Jack in Kansas City, MO on May 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.

    5 of 5 Stars  Dimension Good Product, Do My Own - Great retailer
    By Mel in Florence, AL on January 31, 2012

    Do my own Pest control is great. Good advisors and quick service. I have used Dimension for several years as a commercial applicator. Works great. One caution is in areas where there is not as much sun. the turf in these areas is generally lest hardy. Dimension can damage this turf, so go lightly in those areas if you can. It's ability to kill the crab grass even after it has emerged (very small plants only) allows you to get away with later application. It seems that we get most of our heavy rains before April, so the early applications often seem to be a waste.

    4 of 5 Stars  Works great but don't save any for next year
    By Randy in Browns Summit N.C. on March 8, 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.

    5 of 5 Stars  Prevents most weeds
    By Ron in Foxfield, CO on November 6, 2014

    Where I live we have "weed wars". This past year I did a test patch of 2EW over about 5,000 sq ft in my field grass area + about 6,000 sq ft of turf grass... in both cases, prevented nearly 100% of the weeds. Next Spring, will be doing a broadcast spray over about 2 acres. 2EW is not only competitive in price with similar products, appears to be somewhat more effective, more forgiving for mis-estimating coverage and concentration. Also, good for both warm and cool season grass areas. RECOMMENDED! Suggest giving it a try with the 1/2 gallon size. If it works for you, then save some money with the 2.5 gallon next order.

    5 of 5 Stars  Quality preemergents
    By Tim in Baxter Springs, KS on March 14, 2014
    Verified Purchase

    This is the second half gallon bottle I have purchased in about 4 years. I have about 1.75 acres of Bermuda grass. I used to fight crabgrass. I bought the fertilizer with its preemergent mixed in itself. This was way too costly. Now, I can fertilize cheaper AND control weeds. Because of wind and rain, last year I was late with my application. I remember watching the little crabgrass weeds die. This year, I will spray a second time in the summer. I noticed prostrate coming up in the dry time. Do the math, this is the cheapest way I know.

    By Dave in Broken Arrow, OK on November 15, 2013
    Verified Purchase

    I used Dimension 2EW for the first time last year and the results were great. We have 2.5 acres and the crabgrass, henbit and sand burrs were getting out of control. (10-15% crabgrass in burmuda) I made one application in late February and my timing must have been good. Virtually no Henbit, or grass burrs, and only a few patches of crabgrass emerged. I'm trusting that another application this year will have it licked.

QCan 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

AYou 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.

QDimension 2EW Herbicide used wrongly on pasture, when is it safe to graze this pasture again?
a commercial applicator used the product in a mix for initial weed control which I, ignorantly, allowed to be sprayed on pasture. How long does it take for the chemical to dissipate?

A  Dimension 2EW Herbicide  will stay in the soil up to two years. It will be unsafe for the animals to graze until after the Dimension has left the soil. Since this product was applied off label, you may also contact Dow AgroSciences 800-992-5994 for further assistance trouble shooting this.

April 19, 2015 Rita from Reed City Michigan asked:

QRatio product to water when using Dimension.


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."

QCan Dimension be mixed with Drive XLR8?
I live in Minnesota and have a crab grass issue. Can I mix Dimension and Drive and apply at the same time? Also, would a surfactant be beneficial to use or even possible with the combination?

A As long as you do a tank mix test first to ensure no clumping or adverse effects occur in tank, you can mix both products together to acheive both pre and post emergent control of crabgrass. Since the Drive XLR8 requires the use of a surfactant you can mix that into the tank as well.

A Yes, Dimension 2EW can be applied to bare ground. The sod can be put down immediately after an application of Dimension 2EW. When putting down sod, make sure to do a heavy application of the product to ensure that if the soil is disturbed when putting down the sod, that the weeds will still be prevented. You will use more water, not product.

A Dimension 2EW can be applied below 32 degree when the ground is not frozen and should be done before soil temps reach 55 degree for 4-5 days as that is when seeds begin to germinate.  Timing is always key when applying pre-emergent herbicides depending on the region you are in.
