Per the Prodiamine 65 WDG (Generic Barricade) product label: To reduce the potential to injure overseeded turf, wait 60 days after seeding or until after the second mowing, whichever is longer, before applying Prodiamine 65WDG. So enough time has passed for you to use though we will say that Prodiamine is not labeled to prevent Japanese Stiltgrass and there is no pre-emergent that we are aware that will.
When using a pre-emergent such as Prodiamine 65 WDG, a surfactant is not needed. Only when you are using it as a post-emergent. The mixing ratio of the product with water will not change if you are adding a surfactant. Please review the product label for application instructions.
Herbicides such as Prodiamine will break down in the soil over time, and excess rainfall can increase how quickly that process happens. Ideally, Prodiamine 65 WDG should be watered in within 7 days of application, so unless the snow melts within that time it would be best to go ahead and water in 1/2 inch after application. Prodiamine 65 WDG (Generic Barricade) should not need to be reapplied after snow. More water in the area would just get it into the ground better.
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.
You can use Prodiamine 65 WDG anytime during the year as long as the ground is not frozen or covered with snow or ice and the air temperatures are above freezing. Keep in mind that most spring weeds will start to germinate when soil temperatures reach about 55 degrees, so you do not need to apply if soil temperatures are below that threshold. You will probably need to rotate pre-emergent herbicides throughout the year in Florida since you have an almost constant growing season. This will help you avoid annual maximum application rates of any one herbicide.
The amount of Prodiamine 65 WDG (Generic Barricade) needed for your yard will depend on what type of grass you have. Please review the product label for application instrutcions for your specific type of turfgrass. You may view the maximum application rates per calender year by turfgrass species on page 9 of the product label.
The application timing of Prodiamine 65 WDG will vary according to your specific region. We recommend contacting your county extension office to confirm the right application timing for your area. You may also look over our Lawn Care Schedule on our site with general time frames.
Prodiamine 65 is a WDG (water dispersible granule) formulation which means it must be mixed in a tank sprayer of some sort and applied that way rather than through a hose end sprayer. Hose end sprayers also are not as accurate as tank sprayers and have no way to regulate at what point you have put out a certain amount of product to keep from under or over applying.
You can water the area treated with Prodiamine 65 WDG 24 hours after application.
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.
Typically, apply fall pre-emergent between Sept. 1 and Sept. 15 to control winter weeds. Specifically, apply when soil temperature is 70 degrees and declining.
The first thing you need to know when using an herbicide such as Prodiamine 65 WDG is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 0.185-0.55 oz per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.185-.55 oz of product with for each 1,000 sq ft area that needs to be treated.
Prodiamine will not prevent nutsedge as this is a summer weed that is best treat treated with a post emergent. It also will not effect any weeds that are already growing.
The application timing of Prodiamine 65 WDG will vary according to the exact weeds you are targeting and your specific region. We recommend contacting your local extension office to confirm the right application timing for your area. We do have a Lawn Care Schedule on our site with general time frames that may also be helpful.
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.

One 5 lb. jug of Prodiamine 65 WDG will treat up to 5 acres depending on the rate used. The shelf life is 3-5 years from the date of purchase if stored at room temperature.
Since Prodiamine 65 WDG and Trimec are both different products, used at different times, there would be no need to mix the two. Prodiamine 65WDG is used in the spring and the fall before weeds have germinated and come up. That would not the the time for a post emergent like Trimec. Trimec is used when weeds have already sprouted and are actively growing in temperatures between 65 and 85 degrees, which is not the appropriate time to use Prodiamine 65WDG.
Prodiamine 65 WDG (Generic Barricade) is not labeled to prevent ryegrass and we apologize we are unable to find a pre-emergent that is labeled to do so.
Yes, Prodiamine 65 WDG can be mixed with Roundup as long as the mixing instructions on each product label are followed. Keep in mind that Roundup products are nonselective, so they will kill just about anything they are applied to.

Prodiamine 65 WDG (Generic Barricade) is not labeled for japanese stiltgrass and we are unable to find a pre-emergent that is. We would suggest a selective post-emergent such as Acclaim. Acclaim Extra is a selective post-emergence herbicide that controls annual and perennial grasses in turf including Japanese Stiltgrass. Please refer to product label for specific applications to your turfgrass.
