  • Asked by Greg from Bellevue, Wa

    Q
    When can I cut down blackberry vines after applying Crossbow Herbicide?
    I just applied Crossbow to blackberries in the Spring. However, they are growing fast (in my lawn), and I wanted to cut them down so I can mow my lawn. I have seen that it takes 7-14 days for Crossbow to work on blackberries, but I am specifically wondering if it is still entering through the foliage over this entire time period. In other words, I don't want to cut off the foliage while it is feeding poison to the plant. But at the same time, I need to contain the spread, so that I may now the lawn. I saw a response to a similar question that suggested pruning prior to applying Crossbow. I've already applied Crossbow and would like to know when I can cut without rendering Crossbow ineffective. Thanks!
    A

    Yes, Crossbow Herbicide is still being absorbed in the plant throughout that time period. We do normally recommend that you prune the plant before you apply Crossbow. It is recommended that you wait at least 30 days before pruning the plants once Crossbow has been applied. You can still cut the plant down after application.

    Q
    Could I use a brush to put crossbow on leaf so as not to touch neighboring plants. does it go to root ?
    A
    Crossbow Herbicide is intended to be used with a pressurized sprayer and can be brushed on for stump treatments. If you are only going to be using this for a few plants, it may be better served for you to hand weed the area versus using a non-selective herbicide. It will get to the roots of your plants.

    Q
    How long does it take for Crossbow Herbicide to become rainfast?
    In one answer you stated crossbow to be waterproof in 2 hours, but in another you stated 4-6 hours... which?
    A

    The manufacturer of Crossbow Herbicide does state that this product is rainfast in as early as 2 hours after application.  It is common for most herbicides to be rainfast in 4-6 hours after application, which is likely why you saw that information given.  We apologize for any confusion.

  • Asked by Jackie from Elkins, Wv

    Q
    Will Crossbow kill black walnut tree saplings?
    I would like to cut the saplings down and paint the stump to prevent the black walnuts stump from re-sprouting. Will Crossbow prevent any new growth to eventually kill the tree? Trees are approximately 2-4 inches in diameter.
    A

    Becuase the roots can spread out 50-80ft from the tree, it is advised to cut the stump as low to the ground as possible. Black Walnuts are know for resprouting, using a product with the active ingredient Glyphosate is going to be your best option. Using Roundup QuickPRO which has Diquat as 1 of the 2 ingredients works for a faster knockdown and aborbs throughout the root system better. Below is a step by step guide on how to ensure the saplings won't regerminate.

    Step 1 - Space cuts around the trunk of a mature tree, using a hatchet. These cuts should go down at an angle, exposing some inner flesh of the trunk. Alternatively, cut a straight line around the trunk, removing the bark along the line. For saplings, there's no need to remove bark because the young bark is thin.

    Step 2 - Spray Roudup QuickPRO mixed according to manufacturer's directions, into the cuts in the trunk. Saturate the cuts completely. For saplings less than 6 inches in diameter, spray the herbicide directly on the trunk up to 18 inches high.
    Step 3-Allow the herbicide to move through the tree to the roots for 48 hours. Observe the black walnut's leaves for signs of curl or wilt. If none exists, make new cuts in the trunk and reapply the herbicide.
    Step 4 - (IF YOU HAVE NOT ALREADY REMOVED THE TREE) - Remove the tree by cutting through the trunk about 6 to 12 inches above ground with a chainsaw. You may be able to remove it with an axe if the tree is smaller than 6 inches in diameter. For larger trees, you may need a chainsaw. Choose a safe direction for the tree to fall, and then make the first cut on that side of the tree. Create an undercut or V-shaped cut several inches into the tree, going no farther than one-third of the diameter inward. Go to the opposite side to make a back cut, which is a straight cut that is about the same height as the point of the undercut. As you get close to the undercut with the back cut, the weight of the tree should topple it toward the undercut.
    Step 5 -Spray the top of the freshly cut stump with Roundup QuickPRO, coating it liberally. Repeat every two days for a week or until the stump flesh turns gray. Black walnut trees can send up new suckers from the base of the trunk if the roots aren't killed.

    Q
    How much crossbow per 100 gallons water for pasture land?
    A

    Depending on the types of plants being targeted in the pasture (broadleaf weeds vs more woody brush type plants) the Crossbow Herbicide Product Label states you can use between 1-4 gallons of Crossbow Herbicide per 100 gallons of water. For more mature plants, hedges, and woody brush we would suggest higher application rates for best control.
