    Q
    Is Propiconazole 14.3 the most effective fungicide to treat gray leaf spot on St. Augustine?
    From what I'm reading, it sounds like it preventative and I don't want to waste it if I should be saving it for when I get I cleaned up and then try to prevent it from coming back.
    A

    Propiconazole 14.3 is labeled to be used as either a curative or a preventative fungicide to treat gray leaf spot. You would apply at a rate of 1 - 2 oz per 1,000 sq ft. Use the higher rate for active fungus and use the lower rate for prevention.

    Q
    Can Azoxy 2SC and Propiconazole 14.3 be tank mixed?
    You answered that Azoxy 2sc was a good fungicide to tank mix with Propiconazole 14.3, but you say water in Propiconazole, but on Azoxy, you say it's best if you go 24-48 hours without rain/water after applying. What am I missing?
    A

    Azoxy 2SC Select fungicide and Propiconazole 14.3 both are labeled to be tank mixed with other class fungicides depending on the disease being treated. The waiting time of 24-48 hours is referring to the amount of time before rainfall or irrigation to reduce the risk of runoff into ponds, streams or springs; not the amount of water used during the application. Azoxy 2SC label specifically states to use 2-4 gallons of water per 1,000 sq ft to thoroughly cover the area to be treated. The Propiconazole 14.3  label does not give a specific water amount to be used when applying to turf, just states “sufficient amount water” therefore using the 2-4 gallons of water per 1,000 as indicated on the Azoxy 2 SC would be fine to ensure an adequate amount of water is being applied to ensure both fungicides get into the soil.

    Q
    Can I mix Propiconazole 14.3 with Bifenthrin (insecticide) in my mister/blower and apply at the same time?
    A

    Propiconazole 14.3 would not be recommended to apply in a mist blower as the application would not be sufficient enough due to the particle size of this type of applicator.  It would be best to apply with a pump sprayer so you get sufficient coverage.

    Q
    Should I water in Propiconazole 14.3 when applying at curative rates for brown patch? The label is confusing.
    A

    Propiconazole 14.3 does not require watering in after application for all applications but if treating soil borne you would.

    Per the label: For control of foliar diseases, allow sprayed area to completely dry before irrigation. For control of soil-borne diseases, Quali-Pro Propiconazole 14.3 can be watered in after application.

    We do have some guides here that might help determine which you have to know the most effective treatment method.

    Q
    Will Propiconazole 14.3 work to control oak wilt?
    A

    Propiconazole 14.3 will work for oak wilt. Per the product label, using the product by trained arborists (in injection techniques) as a flare root injection for prevention and treatment works best. We recommend that you contact your local cooperative extension office and/or find an arborist who can help you with prevention methods in case you have trees that haven't been infected yet.

  • Asked by Tim from Collierville, Tn
    06/09/2018
    Q
    How much Propiconazole 14.3 do I mix in the container of my Chameleon Adaptable Hose End Sprayer?
    What setting should I use?
    A

    Since we do not sell the sprayer that you have, we are not sure which settings it may have. Keep in mind that when using a fungicide such as Propiconazole 14.3, it is most important that you are using the correct amount of product for the disease you are treating and the size area, and you should think of the water as a carrier for the active ingredient. Please refer to the product label for the correct rate for the disease you are treating (0.5 – 2 oz per, 1000 sq ft). We recommend using at least 1 gallon of water per 1,000 sq ft. 

    For example, if you are treating for brown patch and using the higher rate, you are applying 2 oz per 1,000 sq ft. If you are treating a 10,000 sq ft lawn, then you should use 20 oz of Propiconazole 14.3 to treat the entire lawn, and we suggest using a setting no higher than 2 oz per gallon of water. You would then treat the entire area evenly using that amount of fungicide in your sprayer.

    Q
    How often can you treat curatively with Propiconazole 14.3 for Dutch Elm Disease?
    I have Cedar Elm trees and noticed the leaves at the crown of the tree turned brown, within a week the entire tree was dead. Surrounding cedar elm trees became infected. I microinjected propioconazole 14.3 given the ratio recommened. I would like to know how often can I use medication to cure the tree from this fungus.
    A

    The Propiconazole 14.3 label states the following:  Preventive applications can be made at 6 to 10 ml/inch DBH. The 6 ml rate provides 24 months control and the 10 ml rate provides 36 months control. Make therapeutic treatment in trees showing disease symptoms at 10-20 ml/inch DBH. Re-treatment may be needed every 12 to 36 months.

    Additionally, Propiconazole 14.3 will be most effective when used in conjunction with other cultural practices for management of Dutch elm disease (removal of dead elm trees, pruning of diseased tree limbs and branches, control of bark beetles, etc

    Q
    Could Propiconazole 14.3 be used on wood in a crawlspace to kill black mold?
    A

    No, Propiconazole 14.3 cannot be used in a crawlspace to kill black mold. It is a fungicide that is labeled to be used in nursery landscape, turf-grass, trees, golf courses, and tree injections. Boracare with Moldcare is the only product that we carry for treating mold on bare wood. Boracare with Moldcare will kill the mold spore but you will need to use a product such as Mold-Clean prior to applying Boracare with Moldcare to remove the mold stain.
