Dimension 2EW Herbicide can be applied around ornamentals. Correct pre emergent application timing varies from region to region. We recommend to contact your Cooperative Extension office and speak with the Master Gardner for the appropriate dates of application this year.
Dimension 2EW should be safe to use around chickens as long as you are following the instructions on the product label. You would need to keep them out of the area until it dries, typically 3-4 hours.
Yes, buffalograss is listed on the Dimension 2EW Herbicide product label as tolerable with a note: Do not use this product on seedling buffalograss in the spring of the first year of establishment until the turfgrass is fully green and has established new roots
Typically you want to mix your Dimension 2EW or any chemical with room temp water or something close to that. Cold water can often cause products to have trouble emulsifying into solution.
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 Herbicide can safely be applied to both cool season and warm season turf, including St. Augustine.
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.
According to the Dimension 2EW Herbicide product label, new sod/seed should not be applied for at least 3 months. Once the sod/seed has been put down, it needs to be established for at least 6 months before applying Dimension 2EW Herbicide again.
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.
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.
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.
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!
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.
No, Dimension 2EW Herbicide will stay in the soil up to two years. It will be unsafe for the animals to graze until after the Dimension has left the soil on pastures.
Dimension 2EW which contains dithiopyr is labeled for use on carpetgrass.
