When wanting to combine two herbicides, we always recommend to follow the herbicide label instruction on tank mixing. You may find the tank mixing instructions on page 3 of the Celsius WG product label and page 7 of Prodiamine 65 WDG product label.
Prodiamine 65 WDG (Generic Barricade) max rate use on Zoysia is 1.0 to 2.3 lbs per acre or 0.36 - 0.83 oz per 1,000 sq ft (per page 11 of the product label).
You could use Resolute 4FL Herbicide, which is a liquid concentrate with the same active ingredient. You could also use a weed and feed called Fertilome for All Seasons Lawn Food Plus Crabgrass and Weed Preventer. The latter is a granule but it does also contain a 16-0-8 fertilizer.
Pendulum 2G is another option for granule pre-emergent which has a very similar list of target weeds.
When used at the lowest rates, you can overseed beginning 4 months after application of Prodiamine 65 WDG. Please see the product label beginning on pg. 13 for complete instructions on overseeding.
Prodiamine 65 WDG (Generic Barricade) is not specifically labeled to prevent carolina geranium. We would recommend using Dimension 2EW instead.
Prodiamine 65 WDG (Generic Barricade) is not labeled to prevent stiltgrass and we are unaware of a pre-emergent labeled for it though there is an article here by University of Ohio that lists some. Depending on your lawn type Acclaim is a post emergent that can be used for it.
Prodiamine 65 WDG is a great selection for your Bermuda turf, it controls many different broadleaf and grassy weeds. For killing the broadleaf weeds I would use 3-way max and for the crabgrass use Drive xlr8.
The amount per acre per year is for the Prodiamine 65 WDG (Generic Barricade) not the calculation of other pre-emergents used on the turf at other times of the year. If each product is applied at the appropriate times and as directed on the product label for your turf species type, it should not cause injury to the established turf.
Prodiamine 65 WDG will inhibit the development of turfgrass species overseeded too soon after application. It will depend upon the rate of product used per acre as to how many months you need to wait before reseeding. At the minimum use rate, you need to wait 4 months before reseeding. Please refer to the product label for complete instructions on reseeding.
There should be no issue using Prodiamine 65 WDG after applying a weed and feed.
Per the Prodiamine 65 WDG product label, "To avoid turfgrass injury, do not apply to newly set sod until the sod has rooted and exposed edges have filled in. This time frame could be anywhere between 8-16 weeks depending on root and turf establishment speed".
You need to wait at least four months after applying Prodiamine 65 WDG before you can put down new sod. There is a chart on page 11 of the product label indicating minimum wait times depending on your location and the rate used. Depending on what kind of grass you are putting down, Tenacity Herbicide can be used just before or at the same time you put down new seed or sod.
Prodiamine 65 WDG would not be affected by a frost after application. It just needs to be applied before soil temperatures reach 55 degrees.
Depending upon where you are located in the country and what type of turf you have, you are generally going to want to do a split application of Prodiamine 65 WDG twice a year to get a longer residual that will last year round. You can use anywhere from 0.5 lbs-0.75 lbs per application, once in the spring and once in the fall. If your 300 gallon tank covers 4 acres then you could use anywhere from 2-3 lbs per 300 gallons per application doing two applications per year.
It is always best to perform any type of maintenance such as dethatching before you put down a pre-emergent like Prodiamine 65 WDG (Generic Barricade) 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 Prodiamine application with at least 1/2 inch of water. Allow that watering to dry completely before dethatching.
Prodiamine 65 WDG is odorless.
Prodiamine 65 WDG will inhibit the development of turfgrass species overseeded too soon after application. It will depend upon the rate of product used per acre as to how many months you need to wait before reseeding. At the minimum use rate, you need to wait 4 months before reseeding. Please refer to the product label for complete instructions on reseeding.
Prodiamine 65 WDG (Generic Barricade) is only a pre-emergent, used to prevent weeds from emerging. It will not kill anything that is actively growing. Hi-Yield Weed and Grass Stopper with Dimension is a very popular pre-emergent herbicide for sandbur. Be sure to check the product label to be sure it is safe to use on your turfgrass. If you are trying to kill existing sandbur, you can browse our post-emergent herbicides for this weed here.
Yes, Prodiamine 65 WDG (Generic Barricade) can be mixed with a post emergent herbicide such as EndRun for control actively growing broadleaf weeds. Be sure to review each product label for tank mix instructions and restrictions.
No, there would not be any benefit to mixing Prodiamine 65 WDG (Generic Barricade) and Surflan Pro Herbicide to apply at the same time. We would suggest making two applications 6 weeks apart at the full rate listed on the product labels for both pre-emergents.
