While creeping bentgrass is listed as a tolerable turf grass, the product label for Dimension 2EW actually states that not all varieties of creeping bentgrass have been tested. It also says do not apply to golf course putting greens, so we are unable to advise that it could safely be used on your home putting green. We would recommend confirming with the manufacturer directly to be sure. Dow AgroSciences can be reached at 800-992-5994.
Dimension 2EW Herbicide is not labeled to be used in areas animals would graze so we cannot recommend it be used in the area. We actually do not have any pre-emergents for grassy weeds in pastures and would recommend contacting your local department of ag for assistance identifying the target weed and for a product recommendation. We can then see if we can get the product.
Dimension 2EW Herbicide is going to be the best pre emergent product when controlling crabgrass. It is labeled to be used in Fescue lawns and can even be applied at a ratio to work as a post emergent.You will use .28-.73 fl oz. per 1000 sq. feet or .75-2 pints per acre. For your 2.5 acre property, 1.875-5 pints will be used to cover the entire area. Please read label for further instruction.
Yes, Dimension 2EW Herbicide can safely be applied to both cool season and warm season turf, including St. Augustine.
Dimension 2EW is safe for pets when used correctly. You would want to keep pets out of the treated area while you perform your application and allow it to dry completely. Once fully dry, it is safe for pets to re-enter the treated area.
It is always best to perform any type of maintenance such as dethatching before you put down a pre-emergent like Dimension so that you do not interrupt the barrier and, therefore, get inconsistent weed control. You could potentially dethatch with a hand rake after watering in the Dimension application with at least 1/2 inch of water. Allow that watering to dry completely before dethatching.
Whether and when you reapply Dimension will depend some on what rate you used when you first applied it. It is possible to do a split application of Dimension, which is usually done with the applications 6-8 weeks apart in Spring. Just be sure that you are not exceeding the maximum application and/or annual label rates for your area and type of turf grass. The rate you used will also affect how long the product lasts in the soil. You can use Tenacity after using Dimension since it is a different active ingredient. Be sure you are always following the label rates for your turfgrass and following any other label precautions. Please let us know if you have other questions.
SnapShot 2.5 TG is not labeled to be used on lawns at all and would not be recommended. Dimension 2EW is our most popular pre-emergent herbicide for both grassy and broadleaf weeds and can be used on both St. Augustine and Centipede lawns. For Southern zones like FL, you would do a fall application by Oct 1st and for spring you would do a second application between February and March 15th at the latest. 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. Tenacity or Atrazine would be good post emergent herbicides for your lawn type.
Dimension 2EW which contains dithiopyr is labeled for use on carpetgrass.

Dimension 2EW Herbicide is a pre-emergent herbicide that is labeled for spotted spurge. It will prevent the weed from germinating. If the weed is actively growing, we suggest selective post-emergent control. If you need a recommendation, please provide your desired turf species and size area. Thank you!
Dimension 2EW Herbicide 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. Remember to follow the more restrictive label directions.
Crabgrass seeds begin to germinate when soil temperatures reach 55 to 60 F and continue to germinate over several weeks from spring into summer. Pre-emergent herbicides such as Dimension 2EW normally should be applied in early to mid-April in southern Iowa, mid-April to May 1 in central Iowa and late April to early May in the northern portion of the state. Pre-emergent herbicides should be applied when the forsythia blossoms start dropping or when redbud trees begin to bloom. I found a great article here by Iowa State that further explains.
