    More useful than Roundup

    By T. on 06/13/2011

    Verified Purchase

    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

    Verified Purchase

    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.

Will Crossbow Herbicide kill briar without harming trees and grasses?
Crossbow is a vegetation management product which means it is not very selective, it will kill almost anything.  Although it will not harm a tree when used at recommended levels if it gets on the base of the tree, it will harm a tree if you spray Crossbow on the foliage.  For applying over grasses you need to make sure you apply at the recommended levels on the product label.
