Prodiamine 65 WDG (Generic Barricade) can be used in a smaller tank sprayer that does not have an agitator as long as you agitate the solution while filling the sprayer and occasionally while spraying. If spraying is interrupted, then be sure to agitate the mixture well before beginning to spray again.
Prodiamine 65 WDG is only a pre-emergent product and will only stop seeds from germinating, it does not have any post emergent abilities to kill actively growing weeds.
When Prodiamine 65WDG is applied as split application, it provides pre emergent control against listed weed for a longer period of time control as opposed to a single application. Fall pre emergent applications should be applied when soil temperatures get to 70 degrees and continue to drop. Spring pre emergent applications and especially for crabgrass control should be made when soil temps reach right around 50-55 degrees.
Prodiamine 65 WDG (Generic Barricade) is a pre-emergent herbicide that typically lasts for 2-5 months in the soil, depending on the rate applied and how much rainfall the area receives. Pre emergents work best when soil temps are close to 70 degrees in the fall and 55 degrees in the spring.
If you are using a pre-emergent like this in an area with gravel or rocks, then it is important to use a higher volume of water when you are applying the product and immediately after the application so that the active ingredient is carried into the soil and does not just get absorbed on the rocks as it's sprayed. This product is safe for pets when used as directed and after the application area is completely dry.
To kill actively growing weeds and prevent weeds from germinating Hi Yield Extended Control is labeled for areas such as gravel, driveways, sidewalks, walkways, patios, etc and will provide weed control for 3-6 months. Hi Yield 365 will kill and prevent weeds for up to 1 year (some weeds may require a second application).
Please keep in mind that thick ground covering will make any application of a pre-emergent difficult, so if you have heavy cover, then you may consider removing the rock and adding an additional barrier such as weed fabric before replacing the rock.
No, Prodiamine 65 WDG will inhibit the development of turfgrass species overseeded too soon after application. It will depend upon the rate of product used as to how many months you need to wait before reseeding. At the minimum use rate, you need to wait 4 months up to 8 months before reseeding. Please refer to the product label for complete instructions on reseeding.
Prior to planting Ruschia Nana, it is recommended that all weeds be removed by hand or killed with a non-selective herbicide such as Roundup QuickPro no sooner than 2 weeks before planting Ruschia Nana. If applying a pre emergent such as Prodiamine 65 WDG (Generic Barricade) to prevent weeds from germinating, this should be done months prior to planting as pre emergent residuals generally stay in the soil 3-4 months.
If Ruschia Nana has already begun to establish, weed control may be done by hand removal or with a hoe or cultivator. Herbicides are generally not recommended as this could also injure the groundcover however Roundup QuickPro can be used and then replug the bare spots after 2 weeks. Removal of weeds when they are small is key and not allowing the weeds to flower which is followed by seeds and will create more weeds weeks later on.
Contact your County Cooperative Extension Office for specific recommendations for your region on any selective herbicides and timing of application information.
For Bermudagrass, Prodiamine 65 WDG is applied 1.0 to 2.30 lbs per acre in no less than 20 gallons of water per acre (0.36 to 0.83 oz with 0.5 gallons of water per 1000 sq ft). If treating 80,000 sq feet (1.8 acres), you will use 1.8 lbs (28.8 oz) to 4.15 lbs (66.4 oz) in a minimum of 40 gallons of water (2 fills of the 25 gallon sprayer). Prodiamine 65 WDG can be applied in a single application or sequential applications for year round weed control as long as you do not exceed 2.3lbs per acre per year. For best results, the prodcut label recommends that the application be watered in with 0.5 inches of rainfall or irrigation within 14 days of the intiial application to help reach the weeds in the soil and pevent germination.
Timing is key when it comes to pre emergent applications. In early spring, pre emergents need to be applied when soil temps are just below 55 degrees as once soil temperatures reach 55 degrees, this is prime conditions for crabgrass to germinate. Refer to the Crabgrass Seed Germination Map on page 8 of the Prodiamine 65 WDG product label for general timing in your region or we recommend contacting the Master Gardener with your County Exension Office for exact timing recommendations in your area.

Yes, Prodiamine 65 WDG may be used in a tank sprayer as long as you are following the instructions on the product label. Water is acting as the carrier therefore you will need to determine how many square feet the 14 gallon tank will cover of the 1 acre you are treating.
For example, if your 14 galllon tank sprayer covers 14,000 sq ft, you will use 7.7 oz of Prodiamine 65 WDG (Generic Barricade) per 14 gallons of water to cover 14k sq ft.
Yes, Prodiamine 65 WDG (Generic Barricade) is labeled to kill Carolina Geranium (crane’s bill)

Prodiamine 65 WDG should not be used on areas where animals graze. We do carry the Prowl H2O Herbicide and Pastora Herbicide WP as options depending on the pasture grass type and target weeds.
Prodiamine 65 WDG (Generic Barricade) can injure desirable seedlings if applied before the secondary roots of seedings are in the 2nd inch of soil (not that plus soil). To reduce the potential of injuring overseeding turf, wait 60 days after seeding or until after the second mowing, whichever is longer, before applying Quali-Pro Prodiamine 65 WDG.
Please view the product label for more information.

Use an initial rate of 0.75-1.5 lbs. / acre (0.28-0.55 oz./1000 sq. ft.) per application
Prodiamine 65 WDG (Generic Barricade) is best applied in late fall and early spring for pre emergent control of weeds.
For Johnsongrass seedlings, we would recommend contacting your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.
Prodiamine 65 WDG (Generic Barricade) is not labeled to control goat head/puncturevine seeds. Depending on the type of area you are treating Pendulum 2G Granular Herbicide can be used for prevention.
If Prodiamine 65 WDG (Generic Barricade) is applied as directed, it should not burn/stain the listed established turfgrass treated. This product is applied to prevent listed weeds from germinating.
We always recommend getting your soil tested to determine the nutrient needs for best results and a healthy green turf. We carry Soil Tests on our website or you can contact your local County Cooperative Extension Office for a soil analysis.
Prodiamine 65 WDG (Generic Barricade) is not labeled to suppress or control dichondra however the product label does advise that injury could occur if applied to dichondra. As mentioned on the product label, “Do not apply Prodiamine 65 WDG to areas where dichondra, colonial bentgrass, velvet bentgrass, or annual bluegrass (Poa annua) are desirable species."
We suggest contacting the manufacturer, Quali Pro, directly for confirmation.
We are happy to assist you with your question, however we there are a few steps you need to take to make sure you are using the correct amount of product for your application.
When using a pre-emergent such as Prodiamine 65 WDG (Generic Barricade), there are going to be a few factors to determine how much product you need to use in your sprayer, mostly what kind of turfgrass you have and how large the treatment area is. You also want to take into consideration how many applications you are making per year so that you do not exceed the annual maximum rate for your kind of turfgrass.
For example, if you have Bermuda grass, the product label indicates that you can use a maximum of 0.83 oz per 1,000 sq ft per year (Table 1 on page 9). If you are making 2 applications per year, that would be 0.415 oz per 1000 sq ft per application. If you are using your 16 gallon tank to treat 16,000 square feet, then you are using 6.64 oz of Prodiamine 65WDG per tank.
While weighing a granule is the best way to insure you are using the correct amount of product, there is a volume chart on page 14 of the label. The 0.4 oz rate would be equivalent to 1.25 tablespoons per 1000 sq ft. So 1.25 Tbsp x 16 = 20 Tbsp or 1.25 Cups per 16 gallon tank in this example.
I hope this helps to clarify. Let us know if you have other questions anytime.
We do not carry the Field King 190571 Lithium Ion Battery Powered Pump Zero Technology Sprayer so we couldn't say for certain what would be best. However based on a cursory Google search of that unit, and finding online it seems to come with the following parts: "4 nozzles included: Brass adjustable, 2 flat fans, and foaming nozzle. Also accepts Tee Jet nozzles." we would suggest using one of the flat fan spray patterns for an even straight swath of product when applying a herbicide such as Prodiamine 65 WDG to the lawn.
There is no time restriction with fertilizers and Prodiamine 65 WDG (Generic Barricade), they can be applied around the same time following each product label.
Prodiamine 65 WDG (Generic Barricade) is a pre-emergent that should be applied in early spring when the soil temps rise up to just under 55 degrees which is the temperature crabgrass germinates. Refer to page 8 of the product label for approximate crabgrass germination dates for Prodiamine 65 WDG. Without knowing what type of turfgrass you have, we cannot give the exact application rate specifically for your treatment but please refer to page 9 of the product label for turfgrass application rates.
Quinclorac would be used when crabgrass is actively growing and temperatures are between 65-85 degrees. Typically a Methylated Seed Oil Surfactant is recommended with Quinclorac for best results. Please refer to the Quinclorac product label for specific rates based on your turfgrass.
