    Q
    How much Crossbow should I use per gallon to prevent a maple stump from growing new shoots?
    We cut down a maple tree a couple of years ago and it is growing shoots like crazy. How do we apply, and what is the mix ratio, to prevent more growth from the maple stump?
    A

    Per the Crossbow product label: To prevent or control regrowth from cut stumps, mix 4 gallons of Crossbow in diesel oil, No 1 or No 2 fuel oil, or kerosent to make 100 gallons of spray mixture.  This breaks down to about 5.12 oz of Crossbow per gallon.

    Q
    How far should I spray Crossbow Herbicide away from an existing lawn that I do not want to kill?
    Gravel driveway with no existing border to the lawn.
    A

    Since Crossbow Herbicide is a non-selective herbicide, it will kill whatever it is sprayed on.  It’s recommended to keep it at least a couple feet away from desired grasses and plants.  Additionally, be sure you’re applying the product on a non-windy day, as spray drift can harm desired grasses.  If needed, you can cover desired grasses and plants with plastic sheeting or a garbage bag during your application for added protection.

    Q
    Will Crossbow Kill Holly? When should it be sprayed?
    A

    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.

    Q
    Will Crossbow kill growing cottonwood trees if sprayed on the leaves with a heavy concentration?
    I have a ditch full of cottonwood trees, 2' saplings to 20' tall, 4” diameter trees. If I spray them with a 5 or 6 oz to the gallon mix will it kill them?
    A

    In order to kill a tree, 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
    What can I use to kill bamboo?
    A

    Bamboo is very difficult to kill since its roots grow so deep. 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 stump it can help kill it out. Bamboo is extremely stubborn, so it can take several steps to remove it completely. You can use also look at using Round Up QuickPro at the highest listed usage rate to help eliminate bamboo. You will still 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
    Can I mix Miracle grow with Helena Crossbow Herbicide?
    I'm spraying my pastures Thursday and I could only find 2 gallons of liquid nitrogen. But I did find miracle grow cheap so I bought 4 boxes. Will it hurt anything. I saw a warning using Npk. What do you think.
    A

    Crossbow may be combined with liquid nitrogen fertilizer suitable for foliar application to accomplish weeding and feeding of grass pastures in one operation per the product label. Use Crossbow in accordance with recommendations for grass pastures as given on this label. Use liquid fertilizer at rates recommended by supplier or Extension Service Specialist. Test for mixing compatibility using desired procedure and spray mix proportions in clear glass jar before mixing in spray tank. A compatibility aid such as Unite or Compex may be needed in some situations. Compatibility is best with straight liquid nitrogen fertilizer solutions. Mixing with N-P-K solutions or suspensions may not be satisfactory even with the addition of compatibility aid. Premixing Crossbow* with 1 to 4 parts water may help in difficult situations. Fill the spray tank about half full with the liquid fertilizer, then add the herbicide with agitation and complete filling the tank with fertilizer. Apply immediately and continue agitation in the spray tank during application. Do not store spray mixture. Application during very cold weather (near freezing) is not advisable.

    Can I apply Crossbow with wick applicator
    A

    Crossbow  can be applied by all types of sprayers, from hand-held models to tractor-mounted spray rigs. While we don't talk to a lot of customers using that method of application equipment, there is nothing prohibiting the product from being used that way for their direct spot treatment needs.
