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

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.

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.

The plants that are well established on my hill are; Hosta, English Ivy, Peony, Bearded Iris, Vinca Major.
Crossbow Herbicide can typically control any woody brush type plants such as ivy, briars, trees, and many weeds. While not labeled to control the other plants you mentioned, its very highly likely it would also kill those if it was sprayed on them or if it got into their root system. If these are desirable plants you want to not harm, we would not recommend using the Crossbow near them.

This product has an attractive price point however it has a relatively low concentration of Triclopyr. What concentration of this product would be effective to kill Tree of Heaven (Ailanthus altissima) when brushed onto a stump or by using the "hack and squirt" method? Thank you
Tree of Heaven is an invasive species that can require chemical and cultural methods to control completely. You will probably need to cut a treat the stumps directly with a product like Crossbow Specialty Herbicide for best results. This article from the PennState Extension service has more information about this difficult tree.

Crossbow Herbicide is specifically designed to kill brush, vines, woody plants like trees, and broadleaf weeds without harming grasses when used at the labeled rates. It will not, however, kill or control moss as moss only grows in areas where you have too much moisture and poor soil conditions where the PH levels are off and the soil is too compacted. Renting a core aerator and running it through the area you have heavy moss concentrations will greatly help. If there are any tree branches keeping that area shaded that you can trim back or cut off then you will want to do this as well so you help keep the area dried out to prevent new moss regrowth. You can spray a moss control product like Lilly Miller Moss Out, however changing the conditions causing the moss is always the best way to go so that repeated sprays aren't necessary in the long run.

The last bunch was cut down a month and a half ago and sprouts are coming up everywhere. Do I have to spray just the leaves or will spraying the visible wood work,too? The area is under an old cedar and fir trees. Is there something stronger I can use?
Crossbow Herbicide appears to be an effective product on salal but it can take mulitple applications. Best way is to either spray the foliage directly or cutting the stumps/sprouts and applying as a “cut stump” as directed on the product label.

I sprayed a combination of Crossbow and Roundup Pro on a house site that was covered with oak trees, wax myrtle and yaupon holly which ranged in height from 5 inches to 24 inches. How long before I should know if they were killed. How long before I can respray?
It can take 2 plus weeks after Crossbow Herbicide application to see that plants are dying. You may reapply if needed 30 days after initial application.

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.
Like well drinking water
Crossbow Herbicide does contain an active ingredient that has soil residual. Per the product label: "This chemical has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination."
If you are applying the product as directed to apply to fresh cut stumps, then there should not be a risk of contamination in most circumstances. However, this product is not labeled for use around aquatic areas or where there is risk of flooding.

Plastic? Glass? I've already read not to use metal and if I use a spray bottle what kind of spray bottle should I use ? all plastic ? I'm using this on a cottonwood tree stump trying to kill the root system
It is recommended to mix and use Crossbow Herbicide is a hand pump or backpack sprayer. We typically recommend the Chapin Premier sprayer or the Chapin Backpack sprayer.
The tree was cut down a month ago, and I now have saplings everywhere, including my crawlspace... The stump is approx 2ft across and sprouting nicely.... I have Crossbow 2-4D and Roundup supper concentrate....
