While Prodiamine 65 WDG (Generic Barricade) is safe for most trees, quercus virginiana is not listed as a tolerable species. It does mention many other oak species. Please be sure to check the label for a full list. We would suggest applying outside the drip line of the tree to ensure proper root growth.
Prodiamine 65 WDG (Generic Barricade) is labeled to help control Yellow Woodsorrel (from seed), and it is not labeled to be used around dymondia. You may use a pre emergent product such as Pendulum 2G instead. This product is labeled to control Yellow Woodsorrel and can safely be applied around dymondia as long as you are following the instructions on the product label.
Yes, Prodiamine 65 WDG (Generic Barricade) can be tank mixed with other pesticides as long as you follow the most restrictive instructions out of the two products you wil be tank mixing.
According to the product label of Prodiamine 65 WDG, as long as you are following the most restrictive instructions of the products you choose. "When using Prodiamine 65WDG in a tank mixture with other pesticides, observe the most restrictive label limitations and precautions on the labels of the products used. Before tank mixing with other pesticides not named on this label, compatibility must be tested." See the COMPATIBILITY TEST section on page 6 of the product label. We normally suggest making two separate applications instead of one tank mix with herbicides and insecticides. If your lawn is under stress, we would recommend doing separate applications.
Prodiamine 65 WDG (Generic Barricade) is only a pre-emergent that prevents weeds from germinating, it would not kill established weeds. Please view our How to Get Rid of Poa Annua Treatment Guide for more information.
Yes, the product label recommends to use Prodiamine 65 WDG (Generic Barricade) with a handpump or backpack sprayer. We would recommend using a mist stream. You would calibrate by determining the volume of water required to treat 1,000 square feet. Use this calibration volume to determine the amount of water and Prodiamine 65 WDG herbicide needed to treat the target area (see the following calibration example).
Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator.
Steps in Calibration:
1. Mark an area of 1,000 square feet (i.e. 20 by 50 feet or 25 by 40 feet).
2. Place the sprayer on a level surface and add water noting the final level of water in the spray tank.
3. Spray the marked area with a sufficient volume of water to provide uniform coverage. Refill the sprayer to the same level as before measuring the amount of water added. The measured water added to the sprayer is the volume needed to cover 1,000 square feet.
4. Determine the application rate (fl. oz./1,000 sq. ft.) for Prodiamine 65 WDG from the Recommendations section of this label.
5. To each volume of water used as measured in step 3, add the amount of Prodiamine 65 WDG as determined in step 4.
Example: If the sprayer uses 2 gallons of water to cover 1,000 square feet and the desired application rate of Prodiamine 65 WDG is 0.185 - 0.055 oz/1,000 square feet, then you would add 0.185 - 0.055 oz of Prodiamine 65 WDG to every 2 gallons of water to be used."
Prodiamine 65 WDG is an effective pre-emergent herbicide for pre-emergent grass and broadleaf weed control. This product will not act as a post-emergent. Timing is very important when applying pre emergent products are you want to be sure to apply before the weeds germinate. For the best timing on when to apply a pre-emergent in your specific region, we would recommend contacting your Master Gardener at your local cooperative extension office.
You may spot treat actively growing weeds with a post-emergent product. In order to make a proper recommendation, we would need some more information.
1. Which specific weeds are you targeting?
2. What type of grass do you have?
3. How much area will you be treating?
For the best timing on when to apply Prodiamine 65 WDG, we would recommend contacting your Master Gardener at your local cooperative extension office as they will have information for your specific region. Please be sure to review the product label for more information and complete application instructions before use.
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 (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.
