Dimension 2EW Herbicide - Questions & Answers

Dimension 2EW Herbicide only needs to have a surfactant added to it when you are using as post emergent application for crabgrass.  Otherwise you do not need one for pre-emergent applications.

You can use a hose end sprayer or any backpack sprayer to apply Dimension 2EW.  Keep in mind herbicides do not give a water amount.  They only tell you how much of the product to apply over 1000 square feet and this will depend on your grass type and program you are using to apply.  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.  Please refer to the product label for complete intructions.

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."

The shelf life of Dimension 2EW is about 3 years. We would recommend keeping the product out of extreme temperatures.

Dimension 2EW is safe to use in container-grown nursery and landscape ornamentals, and in established lawns, golf course fairways, roughs and tee boxes, and commercial sod farms. Please follow the product label for application.

There are no restrictions on 2,4-D being mixed with Dimension 2EW Herbicide. We would recommend doing a small tank mixture first to ensure that there is no clumping in the tank.

A great pre-emergent for grassy and broadleaf weeds would be Dimension 2EW.  Be aware that it will not control anything that is already growing, you would need a post emergent for those depending on the type of grass you have.

Unfortunately there is a not a good selective product that you can use to get rid of the dallisgrass without killing the surrounding grass, too. Your best options once it has emerged is to either spot spray or wipe on something like Round Up, or hand dig up the clumps of dallisgrass down to the root system and re-seed with the fescue.  You could use a pre-emergent such as Dimension 2EW in the Spring and Fall to help prevent it from ever growing.

The first thing you need to know when using an herbicide such as Dimension 2EW is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of area. You will need to use .33 - .73 of an ounce of Dimension 2EW per 1,000 sq ft of area. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your hand pump sprayer (we do not recommend you use a hose end sprayer for this application) with water ONLY, and moving and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix .33 - .73 of an ounce of Dimension 2EW per 1,000 sq ft of product with for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application to ensure best results. is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of area.

Any time you apply an herbicide like Dimension 2EW,  you want to avoid mowing 2 days prior to and 2 days after application.  

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.

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.

How many times the Dimension 2EW will cover that area will depend on what region of the country you live in, what turf you are spraying on, and what weeds you are trying to control. For example: If you are in the South: AL, AR, GA, LA, MS, NC, NM, OK, SC, TN, TX-but not in the regions right on the coast, you would use 1.5 pints per acre, which breaks down to roughly .55 ounces per 1000 sq/ft. You will typically mix this .55 ounces in no less than 2 gallons of water per 1000 sq/ft. At this rate, the 1/2 gallon jug of Dimension would cover 3/4 of an acre almost 4 times as you would be using 16.5 ounces per 33 thousand square feet. You can refer to page 5 of the Dimension Product Label for specific usage instructions.

Dimension 2EW Herbicide can be applied whether the ground is wet or not.  As long as there is no standing water in the parts of the soil that are being treated, it doesn't matter if the soil wet because, unlike a lot of other products, this product bonds to wet or dry soil.
