Dimension 2EW Herbicide states that you must wait 3 months before overseeding after a single application or 4 months after sequential applications. Generally we recommend that you apply a pre & seed in opposite seasons. For example if you apply a pre in the Fall, you will want to seed in the Spring, and if you seed in the Fall you would seed in the Spring.

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.

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.
Yes, Dimension 2EW Herbicide can be used in either fall or spring. However, since every product has a maximum rate per year, we generally recommend using one pre-emergent in the fall & in another in the spring. For example, you could use Pendulum 2G Granular Herbicide in the fall & the Dimension in the spring. You can also consult with your local extension office for the best time to apply.

Dimension 2EW Herbicide does not say how much to use per gallon of water but rather per 1k square feet/acre. In order to determine how much water to use, you'd need to calibrate your sprayer which is about impossible with a hose end sprayer. Below is a video on how to determine how much water to use: https://www.domyown.com/how-much-product-per-gallon-calibrate-your-sprayer-to-find-the-answer-v-539.html
The shelf life of most liquid herbicides (including Dimension 2EW) depends on how they are stored. If the product has been tightly sealed and kept out of sunlight and extreme temperatures, the shelf life is 3-5 years.
