    Q
    Can Crossbow Herbicide get rid of tiger day lilies?
    I dug out a large bed of tiger lilies and planted nicer ones where I thought I had cleaned the tiger ones last fall. Now I see the tiger ones reemerging in a few spots. Can I apply this product to get ride of the tiger ones and would it affect the nicer lilies I planted next to them?
    A

    Crossbow Herbicide can injure the desirable tiger lilies if contact is make with them through spraying/drift.  It is not labeled to control them so would not be recommended for that purpose.  The best option for spot treating in beds is a non selective herbicide such as Avenger or RoundUp QuikPro, taking care to avoid spraying the ones you don’t want controlled, or you can hand-pull.

    Q
    Will Crossbow Herbicide 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.

    Q
    Will spraying Crossbow Herbicide onto the leaves of holly plants (and small holly bushes) adequately kill them?
    A

    Crossbow Herbicide could possibly harm holly but it is not labeled for this plant so we cannot recommend it for controlling/killing it.  Holly shrubs would need to be treated like trees, in which case you would cut the shrubs down to stumps and then treat the fresh cuts. Crossbow Herbicide is labeled for the control of most kinds of unwanted trees. On page 5 of the label you can find directions on how to use for conventional basal bark and stump applications.

  • Asked by Pure from Hawaii
    03/14/2019
    Q
    How much Crossbow Herbicide do I inject into a 30-40 foot tree to kill it?
    A

    In order to kill a tree that size, you would get the best results cutting the tree down to a stump and treating the fresh cut stump directly. If the trunk diameter is less than 6-8 inches, then you could potentially do a basal bark treatment with Crossbow Specialty Herbicide.You would mix 1.25 to 5 ounces per gallon of solution, mixing in diesel No. 1 or 2 or kerosene, then spraying the basal part of the tree up to a height of 15-20 inches off the ground. If you do not need this much product, then could also use Fertilome Brush Killer and Stump Killer.

    Q
    If Crossbow has been used on horse pasture, will the manure contain this weed killer?
    The manure is intended for the garden and will be aged. I am concerned about the safety of using manure from horses grazing on Crossbow treated pasture.

    Crossbow Herbicide can persist in the soil up to 1 year after application so it would not be recommended to use any manure that could have been sprayed for an edible garden area.
