    Q
    How long does it take for Crossbow Herbicide to become rainfast?
    In one answer you stated crossbow to be waterproof in 2 hours, but in another you stated 4-6 hours... which?
    A

    The manufacturer of Crossbow Herbicide does state that this product is rainfast in as early as 2 hours after application.  It is common for most herbicides to be rainfast in 4-6 hours after application, which is likely why you saw that information given.  We apologize for any confusion.

    Q
    Will Crossbow Herbicide kill trumpet vine?
    And how long after can you plant certain hardier flowers or bushes Thanks
    A

    Crossbow Herbicide is the most popular choice for trumpet vine or trumpet creeper suppression. It is very difficult to completely control this plant with a single herbicide application. Per the product label, use a 1.5% mixture as a conventional basal or dormant stem application.

  • Asked by Stewart from Check, Va

    Q
    How do I apply Crossbow Herbicide to kill Tree of Heaven?
    This product has an attractive price point however it has a relatively low concentration of Triclopyr. What concentration of this product would be effective to kill Tree of Heaven (Ailanthus altissima) when brushed onto a stump or by using the "hack and squirt" method? Thank you
    A

    Tree of Heaven is an invasive species that can require chemical and cultural methods to control completely. You will probably need to cut a treat the stumps directly with a product like Crossbow Specialty Herbicide for best results. This article from the PennState Extension service has more information about this difficult tree.

    Q
    Will application of Crossbow Herbicide kill native plants?
    We live on a steep bluff and want to get rid of blackberries but do not want to kill native plants. We have been cultivating natural salal and huckleberry, small madrone, and broad leaf Maple.
    A

    Crossbow Herbicide could affect desirable woody and viney plants that are sprayed with it. You should avoid spraying desirable vines and trees. We suggest spot treating the target plants and spraying when conditions are calm.

  • Asked by Sandy from Vancouver, Wa
    08/09/2017
    Q
    When is the best time to spray Queen Annes Lace (wild carrot) using Crossbow Herbicide on our 4 acre non-grazing pasture?
    A

    If you are planning to use a product like Crossbow Herbicide you would typically want a late summer/early fall application for some of the best results with a post-emergent heribicide. Wild carrot can be difficult to completely get rid of due to their seed cycle, so dilligence and product rotation will be needed, if possible. I have linked for you below a really helpful guide on Wild Carrot and it goes over its life cycle, timing and ingredient recommendations from Michigan State University through their tests and what they found successfull.

    Q
    What time of year is most effective to use Crossbow Herbicide?
    Is December an acceptable time of year?

    Q
    Will Crossbow Herbicide work to get rid of Glory Bower (Clerodendrum trichotomum)?
    We have glory bower that is sending out shoots everywhere and trying to get rid of it entirely. Will crossbow work or is there a better product?
    A

    Crossbow Herbicide should kill Glory Bower as it is a woody plant. We cannot gurantee it however because it has not been tested for it. It may be best to spot treat the Shoots with Round up.

    Q
    After being opened, how long will Crossbow Herbicide still be effective?
    A

    Like with most liquid concentrates, we recommend that you only mix when you are ready to spray. Crossbow should be used within 24 hours of mixing. You should then rinse your equipment throuoghly. This will also prevent any damage in the long run to your sprayer. The storage shelf life of Crossbow Herbicide is 3-5 years if stored in a area that does not allow the product to freeze or reach over 80 degrees

  • Asked by Greg from Falls City

    Q
    Can I use Crossbow Herbicide for killing dormant blackberry plants in the winter?
    A

    Yes, Crossbow Herbicide can be used to kill dormant blackberry bushes and vines. You would apply to thoroughly wet upper and lower stems including the root collar and any ground sprouts. Treat at any time when the brush is dormant and the bark is dry. Best results have been obtained with late winter to early spring applications. Do not treat when snow or water prevent spraying to the ground line. You will use 1.5 gals./acre broadcast application or 1 to 1.5% mixture. Please refer to the product label for complete mixing and application instructions.
