It seems a bit late to treat with Dimension 2EW Herbicide in your area as the weeds are growing and temperatures are above 55 degrees. It can be tank-mixed with post-emergent herbicides. We do recommend applying pre-emergents prior to weed germination and post-emergent herbicides when the weeds are actively growing. If tank mixing, please perform a jar test first and test a small area prior to treating larger areas. Always refer to the most restricted of the two tank mix instructions on labels. We recommend you consult with your county cooperative extension office Master Gardener for specific timing in your area in the spring and fall to apply preemergents such as Dimension 2EW for more effective weed prevention.
In Arizona, you would generally make two applications of Dimension 2EW Herbicide 5 to 10 weeks apart. We would recommend the Program 2 or 3 rates of 1 oz per 1,000 sq ft and then 1.5 oz per 1,000 sq ft, or 2 applications of 1 oz per 1,000 sq ft each, according to the product label. Be sure that you immediately water-in the application with a high volume of water any time there is a barrier like gravel over the ground. This will help get more of the active ingredient down to the soil so that it is not just absorbed into the rocks before it can reach the dirt. (Since this product is still intended to be used around turfgrass and ornamentals, you may not get the same results on a stone area.) At the 1 oz,1000 sq ft rate, you would use 0.22 oz of Dimension 2EW in 1 gallon in your sprayer to cover 220 sq ft. Please confirm with your county Master Gardener at the cooperative extension office for specific timing of application.
Dimension 2EW Herbicide does not kill actively growing spurge but it will prevent it from growing if applied at correct timing.
Please provide the date (including around the time of application) Dimension 2EW Herbicide was applied, the size area treated (sq ft), the amount of product used, and volume of water used. Have you had a soil test done this year? Do you water the lawn regularly? If so, how often? Have you experienced a lot of rain recently on the treated turf? We look forward to assisting you!
We recommend mixing and applying each separately according to the label instructions for each product. Dimension 2EW Herbicide should be applied prior to weed germination at appropriate ground temperatures as directed and the imidacloprid at the correct timing in your area as directed for grubs.
Dimension 2EW Herbicide is safe for warm and cool season grasses when used as directed on the label.
You will use 0.33 - 0.73 of an ounce of Dimension 2EW per 1,000 sq ft. The exact usage rate will depend on your location and the application program you choose. Please refer to pages 4-6 of the Dimension 2EW Herbicide Label to find the exact usage rate for your needs. So if you are treating 30,000 sq. ft. on the low end you would add 9.9 ounces to your 40 gallons of water, or on the high end you would add 21.9 ounces to your 40 gallons of water.
The application of Dimension 2EW Herbicide could last up to a year but it will depend on the specific weeds that you are targeting and your application. Please be sure to review the product label for more information and complete application instructions.
According to the manufacturer's product label, a 3 month wait time for seeding a treated area with Dimension 2EW Herbicide is advised. Although you could till the treated area in attempts to break the preemergent barrier, it is still likely that the germination of the tall fescue seedlings will still be somewhat disrupted, causing less than ideal results.
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 for 3-4 hours.
The manufacturer of Monterey Turflon Ester Herbicide states that you should not use it around or near chickens.
Yes, you can generally mix a post-emergent with Dimension 2EW Herbicide (or any pre-emergent) and apply both at the same time. Just be sure to follow the labeled rates for each product and do a small tank mix test to be sure everything combines well.
Dimension 2EW Herbicide can be shipped & used in the entire state of California, with no restriction to any city.
Dimension 2EW Herbicide should be safe when used as directed. That being said, we are not aware that it has been tested around pollinators and cannot guarantee it would not harm them. We would recommend checking with DOW directly for advice. They can be reached at 800-992-5994
We do not recommend using the grass clippings from a treatment of Dimension 2EW Herbicide in your garden area. Per the product label: "DO NOT use clippings from treated turf for mulching around vegetables or fruit trees." You may view the full product label here. If you need anything else, please let us know. Thank you.
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.
