Dimension 2EW Herbicide
By C.r. on February 20, 2011
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.

Excellent Product for Preventing Crabgrass Emergence
By Chad on May 20, 2013
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.

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.

Dimension Good Product, Do My Own - Great retailer
By Mel 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.

By Tim on March 14, 2014
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.

Use as directed and it works wonders. In 2 years my lawn is now weed free. Not sure how the 1 star rating was allowed to stay since the user didn't have a clue how to use the product. It isn't a post emergence herbicide.

Best lawn I've ever had.
By Dave on November 15, 2013
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.

I had poa annua growing wild in my over one acre of Bermuda. The estimates from the local pest companies were outrageous. I bought Dimension as my first purchase early 2013 and have bought numerous other products since all with great results. Product is terrific when used as pre emergent.

Dimension 2EW Herbicide
By Dennis on September 18, 2011
I was pleased at the quick delivery of the product. It saves me money to use the liquid instead of the granular form of this product.

I applied Dimension mixed with Trimec Classic a little later in the spring than I had wanted. Prolonged windy conditions delayed the application. Crabgrass control over very young plants was as good as the directions specified and the Trimec knocked down all clover and broad leaf weeds. Now, a month after the application the lawn is practically weed free.

May 1, 2011 Pom asked:
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.
March 23, 2011 Mike asked:
QHow much Dimension 2EW would I need to cover two acres?
AYou will need .75 - 3.0 pints of Dimension 2EW per acre. The exact amount you will need will be based on what region you are located in and what program you choose. Please refer to page 5 of the product label for more specific information.
May 1, 2011 Donny asked:
QOnce applied, how long after applying Dimension can we leave the pets outside on the lawn?
AAs 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.
March 5, 2011 Jim asked:
QWhat is the ground coverage for the 1/2 gallon for use on crabgrass?
AYou 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.
January 17, 2011 Pam asked:
QIs Dimension 2EW Herbicide safe to use on St. Augustine lawns? What is the coverage area?
Also, when is the appropriate time to apply in the central Texas area? We've ordered from you before, do you have any special discounts at this time? Thanks.
AYes, Dimension 2EW is safe to use on well established St. Augustine lawns. What season you need to begin applications and usage rate will depend on what you are treating. Pages 4 and 5 of the product label gives you the 3 different options for treatments programs. As for discounts, we do run periodic specials and coupons which we email to our customers that have signed up to receive coupons from us and we always offer a low price guarantee and free shipping.

Ralph from Cerritos, Ca asked:
QCan dimension be used on a dichondra lawn?

Leslee from Massachusetts asked:
QHow Safe is Dimension crabgrass control for young children? What precautions do you recommend
A Dimension 2EW is safe for children as well as pets when used correctly. You would want to keep children out of the treated area while you perform your application and allow it to dry completely. Once fully dry, it is perfectly safe for children to re-enter the treated area.
March 28, 2014
Dave from Minnesota asked:
QI live in Minnesota. When is the best time to apply Dimension 2EW this spring?

March 17, 2014
Derek from Oklahoma asked:
QCan I mix Dimesion with another weed killer such as 2-4-D or RoundUp?
I have always used a pre-emergent on my Bermuda grass yard in the past years and it has worked on a lot of other weeds, but not slowed my crab grass down any. I want to try Dimension on my yard because I have read some really good reviews on it. In years past I have always used my pre-emergent and mixed it with RoundUp in the early spring to knock down the early weeds that have already sprouted. Can I do the same with Dimension?
A Yes, Dimension can be tank mixed with a variety of other herbicides and fertilizers. It is always recommended to do a test mix first to make sure whatever product you are wanting to use with the Dimension blends easily and does not cause clumping or any reaction that would cause your equipment to clog.
March 10, 2014
John from Chapel Hill, Nc asked:
QI have two large inclined retaining walls in my backyard. I presume I can use this product to prevent weeds
Dimension 2EW would be a great pre emergent to use around the retaining wall. Please be sure to check the label to make sure any desirable turf would not be harmed.
March 7, 2014
Jeff from Az asked:
QCan pets be exposed to treated areas with Dimension 2EW after it rains?
You mention it is safe to allow pets in the yard after Dimension dries. Was this referring to the initial application of the herbicide/water mixture and not the equivalent of 1/2" of rain required to activate/spread the herbicide? In other words, should animals be kept away from the yard until after the "soaking process" has dried out. This would seem to take a few days possibly. BTW, thanks for all these Q and As; very helpful.
A The pets need to be off the lawn after the initial application of Dimension 2EW until the product completely dries. After the first initial rainfall dries, the pets can re-enter the treated areas also. After that the product will not reactivate. Please let us know if you need anything else.
February 28, 2014
Dale from Newcastle, Ok asked:
QIs there certain time frame I have after applying this product to get it watered in?
A Dimension 2EW is not effective until activated with 1/2 inch of rainfall or irrigation. Ideally, the Dimension should be watered in within 7 days of application.
