More useful than Roundup

My wife and I own 55 acres of mostly overgrown pasture in south-central Pennsylvania. It wasn't pastured for about 30 years and was taken over by multi-flora rose, honeysuckle shrub, autumn olive, grape, poison ivy, etc. We use a variety of control methods including herbicides (mostly on roadsides and fence rows). The problem with Roundup is that it kills the turf, making an opening for more weeds. One small disappointment is that Crossbow kills rather slowly, but we will probably have little use in the future for Roundup.

Works great on Poison Oak
By Chris on 03/17/2013
Verified Purchase
I have 18 acres of land in Northern California, which is heavily infested with Poison Oak. Crossbow works very well for controlling the Poison Oak. It can take several weeks to see the results after spraying, and re-spraying may be necessary in heavy growth areas. I did three passes in a 2-acre area, with about 4 weeks between each one - each time there was much less Poison Oak to spray, but this meant I got all of the little shoots. One year on from my first spraying, there is very little return growth.

Love it for poison ivy!
By Anonymous on 07/20/2013
I found crossbow after talking with a greens keeper at the local golf course. Cross bow is great at killing all woody brush. I love that I can spray it right thru the grass and all it will kill is the poison and sumac sprouts. It will KILL TREES if you get it on the bark, leaves or root areas so be careful if you are spraying around them. much more potent than regular brush killer and a little goes a long way. economical in the long run.

Works Great
By Jamie on 05/08/2014

I have used Crossbow Herbicide 2x's on the Ivy bed in my front yard. The first time I sprayed I noticed the bright green leaves turning a little yellow after about 3 days. I waited a couple of weeks and sprayed again and the Ivy is now showing to be about 75% dead. I will spray again in another week or so to finish it off. I have also over-sprayed into the yard area and it doesn't kill the grass. Great product

Crossbow on Live Oak sprouts
By David on 09/10/2013
Verified Purchase
I have been using Crossbow on various plants. It really kills blackberries and gooseberries. I mainly have been using it to kill sprouts on Live Oak stumps that were masticated a year ago. It takes a week or so to see results but it eventually works.

I want to mix the least amount of herbicide with diesel and cut the buckthorn and treat the stump
For control of susceptible woody plants and to prevent or control regrowth from cut stumps, Helena Crossbow Herbicide states mix 4 gallons of this product in diesel oil, No. 1 or No. 2 fuel oil or kerosene to make 100 gallons of spray mixture. That would be 4 gallons (512 oz) to 96 gallons (12,288 oz) of kerosene to make a total of 100 gallons. That would break down to 5.12 oz of Helena Crossbow to 122.88 oz of kerosene to make a 1 gallon spray mixture
We would recommend reaching to Chemtrec for information on chemical spills with Helena Crossbow Herbicide, they can be reached at 800-424-9300
No Crossbow Herbicide would not be safe to apply in creek beds at all.
Helena Crossbow Herbicide can be applied in any area you have weeds that need to be controlled that are listed in use areas on the label. The sun does not have a direct effect on the time it takes for weeds to die as long as the mix rates are applied per the product label however applications should be made in early morning or late afternoon evening so avoid any accidental injury to desirable grasses.
I have 78 acres of old orange grove, the pasture has areas very heavy in lantana and would like to kill it since we are using it for pasture grass and cattle can get sick from the lantana
2,4-D compounds are systemic herbicides and will translocate slowly down to the roots. Helena Crossbow containing the 2, 4-D active ingredient would work with the same mode of action however St. Johnswort (goat weed) is not listed on the product label as one of the weeds it will control therefore we cannot advise on the efficacy it would have on the weed.
Some alternative options that are labeled for St. Johnswort (goat weed) would be Bonide Poison Ivy and Brush Killer BK-32 Concentrate (Dicamba and Triclopyr) , Chaparral Herbicide (Metsulfuron methyl) or Alligare 2,4-D Amine Herbicide( 2,4-D). Also using a non selective glyphosate product such as RoundUp is commonly used to spot treat harder to kill weeds.
Review the product labels for application rates and information on Tank Mixing Herbicides if allowed for better results.
St. Johnswort is best treated by spot spraying when it is in flower (Nov–Jan) because it can be easily seen then and is at its most sensitive period to herbicides. Spraying should begin six to eight weeks after substantial rain and when St John’s wort reaches the 50% yellow bud – 50% open flower stage.
I have replaced 4 Thuja evergreen trees in the same spot. I have them professionally installed, and in a few months, they die. I need to find a way to test the soil, as I work in it and it could affect a person's health.
If you would like to get your soil tested, we recommend consulting with your local extension office.
Once Helena Crossbow Herbicide has dried it is safe for chickens to return, typically after 4-6 hours.
Helena Crossbow Herbicide is not labeled for Japanese climbing fern or Old World climbing fern. Unfortunately, there currently are not any selective herbicides labeled to control these invasive vines. Using a non selective such as Roundup QuickPro that contains atleast 41% glyphosate is recommended and repeat application will be needed. Avoid contact with desirable plants by directly spraying or brushing the application onto the vine.
Please review this article from Alabama A&M Extenstion Office for more information.
If Crossbow can be used for back & squirt applications - what would be the mix ratio?
The label for Helena Crossbow Herbicide does not mention using it with the method of hack and squirt.
You would not want to apply the Helena Crossbow Herbicide to any plant you didn't plan to kill completely. The systemic nature of the product would very likely move into more areas of the plant than just where you applied it. Products that are plant growth regulators would typically be used to reduce spread or new shoots/growth from plants that have been trimmed. The Sucker Punch RTU is a popular choice to stop "suckers" - new sprouts from a cut branch or stump. You can review the full Product Label Here prior to purchasing to see if you feel it would fit your needs.
I need to spray blackberries, but deer keep coming and eating the fresh leaves. I don't want to kill or harm them.
Typically any wildlife living in that area is going to move out while you are doing any clearing, walking, towing, or spraying of a product in that area. Products like Crossbow are designed to be safe for people and pets once dry and the safety likely is the same for wildlife. This time of year with hot temperatures surfaces should dry quicker depending on how heavily you put it on the target plants. If you can find anything to do in that area for about 30 min after you spray to help keep the wildlife from moving back in for a bit they should be safe to return to their normal habitats and routine.

Crossbow Herbicide is not labeled to control cattail. You may check out Roundup Custom Aquatic Terrestrial Herbicide as it may be applied to ditches to kill cattail. Please refer to product label for further instructions.
I have a major horsetail problem. It is mixed in with my plants. If i am careful to spray Crossbow only on the Horsetail will it kill my plants?
Helena Crossbow Herbicide will damage ornamental plants such as flowers, shrubs, and trees, so you should not apply it within the drip line of those plants. Crossbow also has soil residual, so you would not want to apply this where you intend to transplant new ornamentals, either. Keep in mind that Crossbow is labeled for control of horseweed (marestail, an annual weed), but not horsetail (a perennial weed).
You could use Sedgehammer Herbicide for control of young horsetail in areas with turfgrass or around woody ornamentals.
