    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
    Can I "paint" Crossbow onto blackberry canes? What dilution?
    My daughter and her husband just bought a house. The previous owner pulled or cut down then mulched over blackberries which are now sprouting up everywhere. This is in the city and the neighbors (and their gardens) are close by. I don't want to risk drifting onto their garden. Can I paint Crossbow directly onto the emerging canes? What dilution would I use?
    A

    Crossbow is labeled to be used on Blackberry at 1.5 gallon mixed solution per acre. For specific treatment procedures: Use a boom type or other broadcast spray equipment that provides uniform spray coverage over the top of the foliage and make applications when plants are growing well. The favorable period for treatment is most likely to occur after full leaf in the spring and continue into early summer, depending on soil moisture and other conditions. 

    Follow up treatment with foliar high-volume or basal type treatments may be needed, especially if treating under less favorable conditions.

  • Asked by Linda from Oregon City, Or

    Q
    Will Crossbow work to kill moss and weeds in my yard without killing my grass?
    A

    Crossbow Herbicide is specifically designed to kill brush, vines, woody plants like trees, and broadleaf weeds without harming grasses when used at the labeled rates. It will not, however, kill or control moss as moss only grows in areas where you have too much moisture and poor soil conditions where the PH levels are off and the soil is too compacted. Renting a core aerator and running it through the area you have heavy moss concentrations will greatly help. If there are any tree branches keeping that area shaded that you can trim back or cut off then you will want to do this as well so you help keep the area dried out to prevent new moss regrowth. You can spray a moss control product like Lilly Miller Moss Out, however changing the conditions causing the moss is always the best way to go so that repeated sprays aren't necessary in the long run.

    Q
    Will Crossbow kill bamboo?
    A

    Crossbow Herbicide is not labeled  for bamboo, however 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.

  • Asked by Sharon

    Q
    Will Crossbow Herbicide kill field mint?
    Ok for horses on field?
    A

    While Crossbow Herbicide is not specifically labeled for field mint, it is a non-selective post-emergent herbicide that targets woody plants and brush such as blackberries and poison oak, as well as annual and perennial broadleaves, so it's quitely likely that it will kill the mint.  Through our research, glyphosate based products treat the problem best, however those products cannot be used in grazing pastures with animals. According to the Crossbow product label: Except for lactating dairy animals, there are no grazing restrictions after using this product. They should not be present during the application and while the surfaces are wet but can return when dry.

  • Asked by John from Vancouver, Wa
    07/19/2018
    Q
    There is a blackberry bush not accessible to spraying can pouring Crossbow on the roots work?
    A

    Crossbow Herbicide is labeled for what is called a cut stump treatment.  A cut stump treatment is where you hack or saw or cut the tree or bush off down at the stump level and immediately drench the roots and/or cut stumps with a concentrated dose of Crossbow Herbicide.  The important thing here is to immediately drench the cut stump after cutting, so you want to mix the product and have it ready to go immediately after cutting it. It may require 2 treatments.
