Dimension 2EW Herbicide - Questions & Answers

Yes, 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 Dimension 2EW Herbicide 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.

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 Dimension 2EW Herbicide Label to find the exact usage rate for your needs.

Since Dimension 2EW is a pre-emergent, you have to wait at least 3 to 4 months before re-seeding your lawn.  Pre-emergents of course will not allow anything trying to germinate to progress, so the grass seeds will not germinate until the Dimension 2EW is gone from the lawn.

You 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 Dimension 2EW Herbicide Label for more specific information.

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.

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.

Both Dimension and Gallery are great pre-emergents and are OK for use around non-bearing vineyards only.  We do not currently carry any pre-emergents that can be used around bearing vineyards.

Centipede is listed as a tolerant grass on the product label. Be sure to read and follow the directions on the Dimension 2EW product label for best results.

To prevent sandburs you should apply Dimension 2EW Herbicide as a pre-emergent in the late fall. Be sure to read over the product label for complete instructions. Sandburs are easier to prevent than to try to get rid of once they have invaded your yard.

Yes Dimension 2EW does need to be watered in with about a 1/2 inch of water to be activated. Many folks choose to apply just before a rainfall and let nature water in the product for them.

Our two most popular pre-emergents for use on established Bermuda grass are Dimension 2EW and Barricade 65WG. Both products do a great job but we recommend checking out the product label on each product to so see which one is labeled to target the weeds you usually have issues with. The product labels are available at each of the links provided in this answer.

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."

Dimension 2EW is our most popular pre-emergent product for use on St Augustine grass. We do recommend that you check out the product label and make sure the weeds you are trying to prevent are listed as herbicides can be pretty specific as to what they will or will not work on.

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.

Dimension 2EW is our most popular pre-emergent for crabgrass and broadleaf weeds. Be sure to review the product label to make sure your lawn species is listed.

You should try to use the bottle up within 3 years of opening the product to insure efficacy. Be sure to store the bottle out of direct sunlight and extreme temperatures.

Barricade and Dimension are actually in the same class of herbicides which means they work with the same mode of action and there would be no benefit to switching between them. We would recommend Barricade because it lasts longer and you will get great control with just Barricade. If you have current weeds (though you should be ahead of the game at this date) try Monument, it will do a great job.

We are unfamiliar with the Spectracide product so we are not sure if this application would be okay. We recommend contacting the Dimension manufacturer directly for more information. You can reach Dow by calling 800-992-5994.

As far as we know, there are no products that exist that control nutsedge as a pre-emergent. The Dimension is one of our best pre-emergents for crabgrass and other broadleaf weeds but will not work for your needs. You would need to use a post emergent product like Sedgehammer to control the nutsedge once it has come up.

As long as the type of turf you have is not Tifgreen(328) Bermuda Hybrid, Dimension 2EW Herbicide is safe to use on all other Bermuda Grasses.
