    Q
    Can Crossbow Herbicide be used on land within the 100' radius of our domestic well?
    We have grasses & weeds we want to kill that in the yard that is inside the 100' radius of our domestic water well. Will Crossbow penetrate down to the water table? Our well is about 100' deep, but, we don't know if there is other points of entry higher up.
    A

    According to the label, Crossbow Herbicide should not be used in areas where the water table is shallow and the soil is permeable because it will contaminate the water. We generally recommend that you use any herbicides at least 10-15 feet away from the well.

  • Asked by Mike from Puyallup
    09/11/2018
    Q
    How far should I spray Crossbow Herbicide away from an existing lawn that I do not want to kill?
    Gravel driveway with no existing border to the lawn.
    A

    It is recommended to keep Crossbow Herbicide applications at least a couple feet away from desired grasses and plants.  Additionally, be sure you’re applying the product on a non-windy day, as spray drift can harm desired grasses.  If needed, you can cover desired grasses and plants with plastic sheeting or a garbage bag during your application for added protection.

  • 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 kill my lawn grass? I'm trying to kill creeping charlie(ground ivy).
    A

    Crossbow Herbicide is not labeled to be used on residential lawns and can harm some types of turf.  A better option for creeping charlie would be 3 Way Max.

    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.

  • Asked by Jo

    Q
    What is the best way to kill black bamboo?
    A

    Crossbow Herbicide is not labeled  for bamboo, but 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, it can help kill it out. Bamboo is extremely stubborn, so it can take several steps to remove it completely. You can use Round Up QuickPro at the highest listed usage rate to help eliminate bamboo. You will 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.

    Q
    I have honeysuckle I want to get rid of but I have roses that are 5 feet away. Will Crossbow kill the roses?
    A
    If Crossbow gets on the roses or within the drip line of the rose bushes it could potentially casue damage. It is important to make sure there is no wind when you are applying the Crossbow to insure that it does not drift onto the roses, and also to make sure that you do not over-spray, because that could allow runoff to flow to the area where the roses are.

    Q
    I am thinning some acreage of some unwanted pine trees. Can I kill them with Crossbow first before cutting them?
    Can I use this product if so what would you say would be the best way? Drilling or hatchet
    A

    Crossbow Herbicide would be best applied to the cut stump after cutting the trees down and will not actually kill mature trees without doing so.

  • Asked by Christopher from Johnsonville
    09/16/2015
    Q
    Will Crossbow harm hops vines in any way? How effective is Crossbow Herbicide against bedstraw?
    A

    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.
