    Q
    When should I apply to prevent spurge?
    Spurge takes over my lawn as soon as the weather gets hot, usually around June.

    Q
    I have a tall fescue lawn. Need to stop poa annua and crabgrass
    I read the poa annua is best stopped if sprayed twice in the fall. The table says to use no more than .36 of an ounce per 1,000sq.ft. per year. So if I do 2 apps in the Fall, and one app in the spring for crabgrass, is each application 1/3 of that .36 ounce? (.12 per 1,000sq.ft.)??
    A

    Prodiamine 65 WDG (Generic Barricade) is not the best recommendation in the fall. It would be best to do 2 applications of it in the spring for crabgrass & other spring weeds at the rate of 1oz per 1k square feet. And in the fall you may do application of Ike's Sandbur and Crabgrass Preventer for the poa

    Q
    Prodiamine wdg 65 water amount
    I get the amount of water prodiamine wdg65 is mixed with doesn't matter as it is just the carrier and that the actual amount is what is important. After applying it needs to be watered in with 0.5" of rain or irrigation within 10 days. Does it matter if it rains more than the 0.5"? What if it rains say 2" Does it move to much product to deep into the soil to be as effective as it should had only 0.5" only let the product get just below the surface?
    A

    Extremely heavy rain could potentially just wash the product away. If you are not sure about the amount of rainfall you will receive, we suggest watering in the Prodiamine 65 WDG (Generic Barricade) with a sprayer.

    Q
    0.36-0.83oz per 1000sq/ft… is it fluid oz or by weight?
    I'm guessing this is supposed to be measured by weight rather than fluid ounces. (Stupid confusing imperial units?)
    A

    Yes, Prodiamine 65 WDG (Generic Barricade) is by weight since it is a granule concentrate. You can see the equivalent measurements on product label on page 14.

    Q
    If I can't seed for 2 months once preemergent is applied. How do I prevent weed growth?
    Field was tilled in fall, crabgrass took over. Is there something I can do to prevent weed growth
    A

    Unfortunately, when the seeding customer will need to decide between seeding or applying a pre-emergent such as Prodiamine 65 WDG (Generic Barricade), we would recommend waiting for soil temperatures to get warm enough & for the weeds to germinate to apply a post-emergent. Next year if you are not seeding, you can apply for a pre-emergent

    Q
    Can Prodiamine 65 WDG be sprayed directly over ornamental plants in landscape beds such as Juniper? I know it's tolerant
    I want to spray right over top of Juniper
    A

    Prodiamine 65 WDG is safe when used as directed around ornamental plantings.  It is only a pre-emergent, used to prevent weeds emerging.  It will not kill anything that is actively growing. It should not be applied over the top of newly planted ornamental plants but should be fine for established plants. Per the product label, should be safe around your junipers. Please refer to the product label for use rates and complete application instructions.

    Q
    Is Prodiamine 65 WDG safe for Timothy grass, but will kill crab grass and clover?
    We loved the Timothy that was growing in our side lot, so we decided to plant more. We want to kill the crab grass and clover that's also growing there, but is safe for Timothy. We have already purchased and applied the Prodiamine. :( Hopefully, this won't harm the Timothy.
    A

    Prodiamine 65 WDG is not labeled to be used on Timothygrass nor is it labeled for pasture grazing areas where this is commonly planted. It will not kill anything already growing as it is a pre emergent that prevents weeds from emerging when applied before they germinate.

    Q
    Applying Prodiamine 65 WDG & Image after putting down The Anderson .48 Barricade
    Putting down The Anderson's 0.48 Barricade Herbicide at low bag rate in Feb. Can I come back in 4-5 weeks and apply Prodiamine 65 WDG (Generic Barricade) and Image with pump sprayer?
    A

    Prodiamine 65 WDG (Generic Barricade) can be applied as long as soil temperatures are below 55 degrees. The Anderson's 0.48 Barricade Herbicide is also a prodiamine based product so you must make sure you do not go over the max rate of either product as that it the max for the active as a whole, whether you switch to a different brand or not. If you need assistance on when to stop applying a pre-emergent in your area, your local extension office can assist you with timing 
     
    Image is a post emergent that would be applied to actively growing weeds, best done with they have just emerged and are young and can be used around the same time as pre-emergents if needed.

    Q
    Applying Prodiamine 65 WDG (Generic Barricade) at 47 degrees
    I live in Oklahoma City where the wind is almost always above 10MPH. Today is one of those rare days that the wind speed is very light. The soil temperature is around 45-50 degrees, according to the forecasts. I see everyone recommends applying Prodiamine when temps are at least 55 degrees, but I never see if it is okay to apply when under that temp. Please clarify.
    A

    Prodiamine 65 WDG (Generic Barricade) should be applied before soil temperatures are below 55 degrees which is different from air temperatures. Here is a video on how to determine your soil temperatures. You may also reach out to your local extension office for timing in your area

    Q
    Can I use Prodiamine WDG and Pendulum both at the same time?
    A

    Prodiamine 65 WDG (Generic Barricade) needs to be applied via a sprayer while Pendulum 2G Granular Herbicide needs to be applied via a spreader so they cannot be mixed. You could put both down the same day but it would best to use one in the fall & the other in the spring instead to rotate to prevent resistance. Pendulum would be a great fall pre-emergent while Prodiamine would be a great spring pre

    Q
    Will Prodiamine 65 WDG control Creeping Charlie seeds? Stolens?
    The label states it is effective against Creeping Charlie, but also states it will not harm stolens of desirable grasses and ornamentals in their dormant state. Creeping Charlie spreads BOTH by seeds and resprouts from tap roots of plants gone dormant. Correct me if I am wrong - This product WILL ONLY prevent the seeds from germinating, and only for the season (time frame) indicated on the label. The seeds of most weeds are viable MUCH longer than one season.
    A

    Prodiamine 65 WDG (Generic Barricade) is not labeled for pre emergent control of creeping charlie (ground ivy). 
     
    Unfortunately, currently there are not any pre-emergents on the market for Creeping Charlie. Control can be achieved by spot treating with a selective herbicide labeled for use in your turfgrass type.
     
    Please view our Creeping Charlie Treatment Guide for more information.

    Q
    I see the length of time of control for crabgrass on the label - Does this interval apply to pigweed?
    Does the time interval for the length of control of crabgrass on the label not apply to other weeds?
    A

    The residual of Prodiamine 65 WDG (Generic Barricade) pre-emergent control can range from 3 to 5 months in lawns and 10 to 16 weeks in landscape beds. Split applications are recommended for longer control or to apply at a higher application rate in a single application.
