    Q
    Is there a green, natural, or organic Crossbow Herbicide?
    A

    Unfortunately, we are not aware of a natural or organic herbicide that would be comparable to Crossbow Herbicide. We do sell Avenger Weed Killer Concentrate, an organic herbicide that is non-selective.

    Q
    How much crossbow per 100 gallons water for pasture land?
    A

    Depending on the types of plants being targeted in the pasture (broadleaf weeds vs more woody brush type plants) the Crossbow Herbicide Product Label states you can use between 1-4 gallons of Crossbow Herbicide per 100 gallons of water. For more mature plants, hedges, and woody brush we would suggest higher application rates for best control.

    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.

  • Asked by Janice
    06/03/2017
    Q
    Does Crossbow kill grass?
    A

    Crossbow Herbicide is not to be used on bentgrass or newly seeded grass.

    If you are wanting a bareground herbicide to kill whatever it is applied to, we would recommed using Pramitol 25E. If you are wanting to treat grassy weeds in ornamental beds and landscaped areas, Grass Out Max is a selective herbicide that can be sprayed without harming desired plants. 

    Please read all product labels for application rates and instructions.

    What kind of sprayer works best with Crossbow Herbicide? Is a hose end sprayer okay to use?
    A

    You can use either a hand pump sprayer or a hose-end sprayer with Crossbow Herbicide. If you are using a hose-end sprayer, be sure that you have calibrated the sprayer so that you are using the correct amount of herbicide over the area that you are treating.

  • Asked by Sandy from Vancouver, Wa

    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
    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 Steve from Or
    09/21/2016
    Q
    Why are there weeds that keep emerging through the middle of dead weeds after 3 applications of Crossbow?
    Why is this not working?
    A

    Crossbow Herbcide is a post-emergent herbcide and will only kill the weeds that are actively growing at the time of application. If there are weeds under the soil that have not germinated yet, those weeds will not be affected by Crossbow. To treat weeds that are in the soil that have not germinated, you would need to use a pre-emergent in the spring/late fall before the soil temps reach 55 degrees. Another option is to continue to treat with Crossbow as the weeds emerge.

  • Asked by Greg from Falls City
    01/03/2019
    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.
