    Can I spray Crossbow at the base of 20+ ft. maples to kill vines or other plants?

  • Asked by Shelley from Portland

    Q
    Can Crossbow hurt an oak tree if exposed?
    I've got vines growing on my Oak Tree that I want to kill but I don't want to harm my tree. If I spray the vines at the base of the tree getting some Crossbow on the tree trunk but not the tree foliage, will my tree be ok?
    A

    Crossbow is a vegetation management product which means it is not very selective, it will kill almost anything.  Although it should not harm a tree when used at recommended levels if it gets on the base of the tree, it will harm a tree if you spray it on the foliage.

    Q
    If Crossbow has been used on horse pasture, will the manure contain this weed killer?
    The manure is intended for the garden and will be aged. I am concerned about the safety of using manure from horses grazing on Crossbow treated pasture.
    A

    Crossbow Herbicide can persist in the soil up to 1 year after application so it would not be recommended to use any manure that could have been sprayed for an edible garden area.

  • Asked by Donald from Spirit Lake , Idaho
    05/03/2021
    Q
    How does crossbow kill plants ? How soon can I plant shrubs and trees in treated area?
    Are there any precaution to avoid killing desired plants after treating with crossbow such as soil mused to plant shrubs and trees. Some of our evergreen trees have exposed roots , will crossbow harm tree if spray on roots?
    A
    Since Crossbow Herbicide is a non-selective herbicide, it will kill whatever it is sprayed on.  It's recommended to keep it at least a couple feet away from desired ornamentals, bushes, trees, shrubs, etc. Additionally, be sure you're applying the product on a non-windy day, as spray drift can harm desirables.

    Q
    Will Crossbow Herbicide kill Asiatic/Oriental Bittersweet?
    It's roots are literally under my entire lawn, and who knows how far reaching, crisscrossing, some nearly an inch in diameter, and lengths in the hundreds of feet. I got it "visually" under control in the front of the property, though it decided to invade the back. I've discovered it's roots have punctured through other plants' roots/tubers, like the daylillies or peonies. IT MUST BE STOPPED!!!
    A

    Asiatic/Oriental Bittersweet is an invasive species and difficult to eradicate and control. We recommend that you speak to the manufacturer Dow AgroSciences for information on treating with Crossbow as it is not listed on the label. They can be reached at 800.992.5594. We also suggest speaking to a Master Gardener in your area by clicking the link below for more treatment advice.

    Q
    Does it kill Japanese barberry?
    I have acres of woods being taken over by barberry. I last sprayed with Cleanout but some shoots are returning. I need a real killing spray.
    A
    Unfortunately we do not carry any products labeled to treat Japanese Barberry. However, after doing some research on a couple university websites, we have found 2 active ingredients that have been known to kill Japanese Barberry. Cutting the stump and applying products with the Active Ingredients,  Glyphosate or Triclopyr has been shown to have great results for killing Japanese Barberry. Crossbow does contain the active ingrdient Triclopyr.  We recommend contacting your local extension office to get a confirmation that this would give you the results you are looking for.

    Q
    My husband sprayed trumpet vines 3 -4 ft from grapes with Crossbow, how can I stop it from getting yellow and wilting?
    I noticed the yellow leaves are more under and not on top of the grape vines
    A

    As long as Crossbow is not applied directly to the grapes or the drift did not contact the grapes that would not be the cause of the yellow and wilting leaves.  It would be best to further examine the grape vines to confirm if a disease or other issue could be the cause.

    Q
    Will Crossbow harm fruit trees if sprayed around their trunks?
    A

    The product label for Crossbow Herbicide only lists that it can be used in non crop areas and specifically states: Do not apply directly to, or otherwise permit it to come into direct contact with cotton, grapes, tobacco, vegetable crops, citrus, flowers, fruit or ornamental trees, or other desirable broadleaf plants and do not permit spray mists containing it to drift onto them.

    Based on this information, we would not recommend applying it anywhere near the fruit trees.
