  • Asked by Greg from Falls City
    01/03/2019
    Q
    Can I use Crossbow Herbicide for killing dormant blackberry plants in the winter?
    A

    Yes, Crossbow Herbicide can be used to kill dormant blackberry bushes and vines. You would apply to thoroughly wet upper and lower stems including the root collar and any ground sprouts. Treat at any time when the brush is dormant and the bark is dry. Best results have been obtained with late winter to early spring applications. Do not treat when snow or water prevent spraying to the ground line. You will use 1.5 gals./acre broadcast application or 1 to 1.5% mixture. Please refer to the product label for complete mixing and application instructions.

    Crossbow should NOT be applied to water areas to treat cattails as it is extremely toxic to fish and not labeled for that usage. We do carry Rodeo Herbicide is a very popular glyphosphate herbicide for the control of aquatic weeds and plants including mature cattails.
