    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.

    5 of 5 Stars  Best lawn I've ever had.
    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.

I'm in north Florida and have several established citrus and fig trees. Is this product okay to use on my lawn around them without making the fruit from these trees unsafe to eat?

March 8, 2015 Robert from Ozark Arkansas asked:

QJust ordered Dimension 2/8/2014 . I live in Arkansas west central. Want to use when received.
I want to control crab grass in Bermuda grass. Do you have any suggestions?

A With Dimension 2EW, there are various plans you can chose from. Plan 1 provides about 3-5 months of pre-emergent crabgrass control. This is the plan most individuals go with because it is for residential lawns. You will use 0.28 fl. oz. per 1000 square feet. Water is a carrier of the product so we recommend using at least 2 gallons of water to ensure you are getting the right amount of product into the ground to control the pre-emerging weeds. Once the product is down, it is recommended that you water the product in again to activate it.

QHow soon can I replant a tree after a pre-emergent application with Dimension 2EW?
I plan to plant nursery trees this spring, but after an application of Dimension 2EW has taken place. How long should I wait before planting?

A Dimension 2EW is labeled to be used over the top of ornamental plantings so while it would not harm the trees if applied before planting you would be disturbing the soil barrier that Dimesion creates if planting after application and it may be as effective as it should be.  It would be best to apply after you have planted the nursery trees.

February 10, 2015 Jeff from Phx Az asked:

QDimension in Phx AZ
Each summer I have a crab grass battle. My lawn is over seeded with perennial rye in the winter, and is bermuda in the summer. Based on the Q&A, it seems as though applying Dimension now (Feb,) will kill my existing rye prior to the bermuda coming in (late April/May). If I were to wait until April/May, would it still be effective as a pre-emergent? It seems like crab grass would already be getting a foothold by then.

A Dimension 2EW needs to be applied before the seeds germinate in order for it to work properly. It is also labeled for early post emergence of crabgrass. It will likely not work as effectively if it is put down in April/May if the crabgrass is already out. We would recommend following the rule of thumb and putting the product down in early to mid February.

QDimension 2EW and Gallery 75 DF mixing instructions
I am going to mix both Dimension 2EW and Gallery 75 DF in a Chapin 61900 backpack sprayer and use on my Houston, Tx St Augustine grass. I am following 2EW program 1 - 0.55oz and I think if I am reading correctly 0.50oz of Gallery 75 per 1000 sqft. (that sure does not like much at all). Do I use the recommended amounts from both labels since I am mixing the 2 together? Also after the I apply this on Feb 1 how soon can I reapply again? I have crabgrass, clover and spurge in my yard.


Yes, you will mix the amounts as specified on the label. It does not sound like a lot, but it is enough product to treat the area in at least two gallons of water.

Re-applications and timing will depend specifically on what program you choose to use. Please review page 4 of the product label to determine the program that will best suit your needs for Dimension 2EW. The same will go with Gallery 75.

January 17, 2015 David from Grosse Tete La asked:

QLooking for a weed killer
I'm looking for a weed killer for crab grass (stickers) and clover without hurting my ST Augustine grass. I have these stickers everywhere in my good grass.


Unfortunately their is not a selective product that will remove crabgrass from St. Augustine.  St. Augustine is a very fragile grass, and so most selective products that are labeled to remove crabgrass and not your real grass, will hurt the St. Augustine.  It is recommended to kill the crabgrass with a round up type product, like Ranger Pro, which will also kill just the St. Augustine around the crabgrass that it is sprayed on, and then a couple weeks later re-seed those areas with new St. Augustine. 

Image 70 DG is labeled for the sandbur and white clover as well as crabgrass suppression though.

For long term control though, you should apply a pre-emergent in the late fall and early spring which will prevent new crabgrass from coming up next year.  If you apply pre-emergent every year, you should not have issues with crabgrass long term.  Dimension 2EW is one of our most popular pre-emergents for crabgrass.  Dimension would also be good for the clover and stickers.
