Crossbow Herbicide

Crossbow is a non-selective post-emergent herbicide that targets woody plants and brush such as blackberries and poison oak, as well as annual and perennial broadleaves, while leaving grasses unharmed. Crossbow achieves excellent control of woody plants and brush and can be applied by all types of sprayers, from hand-held models to tractor-mounted spray rigs. Except for lactating dairy animals there are no grazing restrictions following the application of Crossbow Herbicide.  Crossbow is rainfast within two hours after application.

The manufacturer is now HELENA, no longer from DOW. Same product just different manufacturer. 

This product is not labeled to be applied to home lawns.

Crossbow specialty herbicide is recommended for control of most species of unwanted woody plants, as well as annual and perennial broadleaf weeds, growing on rangeland, permanent grass pastures, CRP, fence rows, non-irrigation ditchbanks, roadsides, other non-crop areas, and industrial sites.

For use on plants in non-crop and non-timber areas only. Not for use on crops, timber, or other plants being grown for sale or other commercial use, or for commercial seed production, or for research purposes.

    4 of 5 stars  More useful than Roundup
    By T. in McConnellsburg, PA 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.

    5 of 5 stars  Works great on Poison Oak
    By Chris in San Jose 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.

    5 of 5 stars  Love it for poison ivy!
    By in wapwallopen PA 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.

    5 of 5 stars  Works Great
    By Jamie in Winston-Salem, NC 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

    5 of 5 stars  Crossbow on Live Oak sprouts
    By David in Nevada City, CA 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.

    5 of 5 stars  Powerful Stuff
    By Ron in South Florida on 08/05/2017

    We are in South East Florida. Property Area is Very Small-Compressed, Less Than 1/4 Acre. ..I have surrounding neighbors whom Do-Not maintain their Bushes that grow into my chainlink fence and grow outta control. After Spraying Crossbow it Will STINK For Many Weeks...WOW! I spray Crossbow on the Bordering Neighbor Fence to Knock Down all Kinds of Shrub Growth, Weeds I Don't Know The Species Name. Here in South Florida, Bougainvillea plants are a Vine that will take over a large area rather fast. I wiped-out Bougainvillea with Crossbow on the neighbor's fence, but the Crossbow took many many months to do its job. I uses a 1.5% mix in a HomeDepot 1 Gal Pump Sprayer.

    3 of 5 stars  Crossbow vs. Creeping Charlie and Canadian Violets
    By Dennis in Homer on 07/27/2017

    I tried 1% solution on both Creeping Charlie (Ground Ivy), and Canadian Violets. It did not seem to be working after about two weeks. I hit it again with a 1-1/2 % solution and some of the Creeping Charlie is getting a yellow look after about two weeks, the Canadian Violets seem unaffected. Also, Crossbow seems to result in a participant with mixed in my sprayer (Fimco boom) and plugs the strainer screen. I am not sure that Crossbow is the answer to those two problem weeds.

    5 of 5 stars  A Powerful Herbicide For Tough To Kill Weeds
    By Robertm. in Marion, Ohio on 07/25/2017

    Crossbow is based on 2/4/D herbicide. It has additives to increase it's absorption and make it work better on tough, woody plants like briars, honeysuckle and elderberry. It doesn't kill most grasses. Cost wise, it's a lot more expensive than generic 2/4/D or glyphosate. So, I recommend that you read the data sheet and only use it for what it's intended. But, it does the job where regular herbicides aren't effective. Don't forget that 2/4/D drifts. Be careful where you spray it.

    By Jerry in Arp on 04/06/2017

    4 of 5 stars  Target: Lawn Violets & Creeping Charlie
    By Darel in Chesterton, IN on 09/26/2016

    I've never run across a more difficult invader than the lawn violet. These dang things are next to impossible to eradicate. I sprayed a mix of Crossbow (with dish soap) on them several weeks ago and they're still surviving. I have noticed that the edges of their leaves are getting brown but why is it taking so long to kill them??? On the other hand, creeping charlie is no match for Crossbow as all that I sprayed are completely withered and dead. While I was spraying I also hit all the dandelions that I saw and man does this stuff ever annihilate them! It turns them completely BLACK like someone burned a hole in your lawn. Beware though because it will also kill the grass which I'm not happy with but I can live with that. Crossbow is a strong herbicide so be carefull and mix only as directed.

    5 of 5 stars  Works!
    By Ndrw in Virginia on 06/26/2016

    We love this! It kills the rampant plantain and wild violets that were taking over our 2 acres of grass. It kills the other weeds, too, such as poison ivy, ivy, etc. It does take longer to have a total kill but it DOESN'T kill the grass if you put it on while the grass is vibrantly growing (cooler weather.) If you use the 1.5% mixture, the grass yellows but comes back. You may need to make a second spot application with the 1% mixture but will get most things and leave the grass untouched. Try to put it on while the temps are in the 70's for the fastest uptake and kill.

QWill Crossbow Herbicide kill briar without harming trees and grasses?

ACrossbow 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.

QHow long does it take for Crossbow Herbicide to become rainfast?
In one answer you stated crossbow to be waterproof in 2 hours, but in another you stated 4-6 hours... which?
