Dimension 2EW should not be applied within the drip line of any fruit trees. Also, the label does state that if your lawn is treated with Dimension 2EW, the grass clippings should not be left around the fruit trees.
Dimension 2EW is a pre-emergent herbicide, so it is best applied before soil temperatures reach those that are optimal for the weeds you are targeting. This is generally before soil temperatures reach 55 degrees in the Spring. You should not apply when there is snow on the ground or temperatures are below freezing. In the Fall, you would want to apply before soil temperatures cool to those favorable for these weeds, usually below 70 degrees. We recommend contacting your local Cooperative Extension for the best recommendation on timing in your area.
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.
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.
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.
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.
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 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.
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.
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.
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
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. For example, if Program 1 is done (which is the most recommended for residential lawns), it will provide 3-5 months of pre-emergent control. Most pre-emergent products will have to be applied at least twice a year to prevent Spring and Summer weeds. Be sure that you do not exceed the maximum annual rates for your specific type of turfgrass.
Dimension 2EW is not labeled to be used in edible gardens. We do carry the Vegetable & Ornamental Weeder that is safe for that use.
Dimension 2EW provides pre-emergence and early post-emergence control of crabgrass, and season-long control of crabgrass, goosegrass, foxtail, spurge and many other grassy and broadleaf weeds.
SpeedZone is an excellent selective post-emergent herbicide for common and troublesome weeds in turfgrass such as spurge, pennywort, dandelion, white clover, and many others. Evidence of injury can be seen within hours of application, and weeds will die in as little as 7 to 14 days.
