    Q
    What can I use to kill bamboo?
    A

    Bamboo is very difficult to kill since its roots grow so deep. We have heard if you cut down the bamboo level with the ground and apply Crossbow or a similar Triclopyr based product undiluted to the fresh-cut stump it can help kill it out. Bamboo is extremely stubborn, so it can take several steps to remove it completely. You can use also look at using Round Up QuickPro at the highest listed usage rate to help eliminate bamboo. You will still be required to cut the bamboo down to a short stump and then apply the Round-Up QuickPro. It can take several applications to achieve the desired results.

  • Asked by Tim from Milltown
    03/19/2021
    Q
    Will Crossbow leak into the groundwater after heavily applied to the fresh cut stumps of the "Tree to heaven"
    Like well drinking water
    A

    Crossbow Herbicide does contain an active ingredient that has soil residual. Per the product label:  "This chemical has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination."

    If you are applying the product as directed to apply to fresh cut stumps, then there should not be a risk of contamination in most circumstances. However, this product is not labeled for use around aquatic areas or where there is risk of flooding.

    Q
    Can I apply Crossbow with wick applicator
    A

    Crossbow  can be applied by all types of sprayers, from hand-held models to tractor-mounted spray rigs. While we don't talk to a lot of customers using that method of application equipment, there is nothing prohibiting the product from being used that way for their direct spot treatment needs.

  • Asked by Donald from Spirit Lake , Idaho

    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.

  • Asked by Minerva from Northern Vermont

    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.

    Will Crossbow harm hops vines in any way? How effective is Crossbow Herbicide against bedstraw?

    Crossbow Herbicide targets vines and brush and could harm hop vines if the spray contacts them. Crossbow can be used to treat annual bedstraw as a foliar spray. Please refer to pages 2-3 of the product label for this application.

  • Asked by Bill
    04/17/2016
    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.

    Q
    Can I use Crossbow for willow bushes coming up in my lawn?
    We have wild willow shrubs invading our bluegrass lawn, up to 80 ft away from shrubs. Will Crossbow kill the emerging willows without harming the bluegrass? What about trumpet vine sprouts? Thanks
    A

    Crossbow Herbicide is not actually labeled to be used in lawns so we cannot recommend it for this use. Fertilome Brush Killer and Stump Killer has the same active ingredient at a lower percentage but is labeled for both willow and trumpet creeper aka trumpet vine and is for residential use.

    Q
    Are asparagus plants affected by residual Crossbow?
    I have an acre of dormant asparagus plants I need to control perennial clover, sow thistle and blackberry. Can I spray now and not have residual effect when new stalks emerge in mid February?
    A

    Crossbow Herbicide is only labeled to be applied in non crop lands per the product label and it can last up to 12 months in the soil and inhibit seed germination or plant growth.  We would recommend checking directly with Dow to confirm if you can plant in treated soil in February.  Dow can be reached at 800-992-5994.

    Q
    Is it okay for the temperature to drop below 55 degrees after Crossbow has dried and become rainfast?
    A

      If temperatures drop below 55 degrees after Crossbow Herbicide has been applied, this may lengthen the amount of time it takes to kill the weeds.
