    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
    Will Crossbow Herbicide kill trees if it is applied close to them?
    A

    Crossbow Herbicide should not harm established trees if it is not applied directly to them.   Take care to apply when the wind is calm to minimize drift.

    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.

    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
    06/14/2017
    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 cattails in my pond?
    A

    Crossbow Herbicide is toxic to fish and may be toxic to aquatic invertebrates and is not labeled to be used in ponds.  Diquat Water Weed and Landscape Herbicide would be a better option as it is an aquatic herbicide labeled for cattails.

    Q
    Is Crossbow Herbicide safe to touch or cut the dead poison oak plant?
    Once poison oak has died after spraying with Crossbow (say 2-3 weeks after), is it safe to touch the dead poison oak or is there residual urushiol in the plant? Looking for the safest way to actually remove and dispose of the dead plants. Thanks!
    A

    Even after killing the poison oak with Crossbow and is "dead", it still contains rash-producing oils and is recommended to avoid direct contact. Wear rubber gloves and handle dead plants carefully. Dispose of plants and rubber gloves in tightly sealed garbage bags. Thoroughly wash clothes in hot, soapy water. Clean garden tools, too, either by wiping them down with rubbing alcohol or by washing in hot, soapy water.

    Q
    Will Crossbow Herbicide kill sandspurs in bermuda and centipede lawn?
    A

    Crossbow Herbicide is not labeled to control sandspur aka sandburs nor for use in home lawns.  This is a summer weed that is actually easier to prevent then to kill once emerged.  We would recommend applying a pre-emergent like Dimension 2-4 weeks ahead of when it germinates.  You can check with your County Extension Offices for the correct timing.

    Q
    Is Crossbow safe to use around azelia bushes, daffodils and burning bush shrubs?
    I'm using 3"- 5" rock in my beds (I installed weed block underneath) but I'm getting all sorts of clover and grass growing on top.
    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.  Gordons Ornamec would be a better choice. This will eradicate grassy weeds but not clover. You may need to spot treat with a glyphosate product carefully like Killzall for the other weeds or manually remove them.

    A

    The Crossbow Herbicide is labeled for the supression of Trumpet Vine, but it will not kill it off completely.
