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 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. Over 100 degree weather will be too hot/late to apply a pre-emergent.
According to the Dimension 2EW Herbicide product label, new seed should not be applied for at least 3-4 months after an application.
Yes, Dimension 2EW Herbicide does control sandburs. Be sure to check the label with regards to how much to use for your area.
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.
Unfortunately their is not a selective product that will remove crabgrass from St. Augustine. St. Augustine is a very fragile grass, and so most selective products that are labeled to remove crabgrass and not your real grass, will hurt the St. Augustine. It is recommended to kill the crabgrass with a round up type product, like Ranger Pro, which will also kill just the St. Augustine around the crabgrass that it is sprayed on, and then a couple weeks later re-seed those areas with new St. Augustine.
Image 70 DG is labeled for the sandbur and white clover as well as crabgrass suppression though.
For long term control though, you should apply a pre-emergent in the late fall and early spring which will prevent new crabgrass from coming up next year. If you apply pre-emergent every year, you should not have issues with crabgrass long term. Dimension 2EW is one of our most popular pre-emergents for crabgrass. Dimension would also be good for the clover and stickers.
Dimension herbicide is a pre emergent that targets crabgrass, dandelions and other listed weeds and grasses. 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
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.
Dimension is best applied just before temperatures are suitable for weed seed germination. For crabgrass, this is when soil temperatures are about 55 degrees F. You will need to check your local weather forecast for a time when you will have several warm days in a row so that you can apply before that time for best results. You can usually check local soil temperatures online, too. You should not apply Dimension or other pre-emergents if the ground is frozen, if there is snow or ice on the ground, or if the ground is already saturated from rainfall.
Dimension 2EW is not labeled to be used in edible gardens. We do carry the Vegetable & Ornamental Weeder that is safe for that use.
The length of time Dimension 2EW Herbicide lasts depends on the rate used, it can last 3-6 months.
For Dimension 2EW Herbicide you would really need to plant first and then apply, otherwise during planting you would be disturbing the barrier that Dimension creates and it will not be as effective.
Per the product label: For ornamentals within non-crop areas, apply only after transplanting when soil around roots has been thoroughly settled by rainfall or irrigation and no cracks are present, and only to plants listed in the Tolerant Ornamental section of this label, or injury may result
Whether oryzalin or dithiopyr is the best choice for you will depend on what weeds you are targeting, where you need to apply the product, and what price point you are wanting. Dithiopyr, which is the active ingredient in Dimension 2EW Herbicide, is the preferred pre-emergent for crabgrass and also covers a variety of other grassy and broadleaf weeds. Dimension also has the unique quality of offering early post-emergent control of crabgrass. Oryzalin (Surflan) is economical and can be used in some areas where Dimension may not be able to be used. Always be sure to check the product labels for whether the product you want to use is appropriate for your needs and safe to use around your target areas. Please let us know if we can further assist you.
Dimension 2EW is one of our most popular pre-emergents for crabgrass as well as many other broadleaf weeds, and it can safely be used on St. Augustine grass. Please check the product label to ensure that it will control the other weeds that you are targeting.
