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.

I just applied Crossbow to blackberries in the Spring. However, they are growing fast (in my lawn), and I wanted to cut them down so I can mow my lawn. I have seen that it takes 7-14 days for Crossbow to work on blackberries, but I am specifically wondering if it is still entering through the foliage over this entire time period. In other words, I don't want to cut off the foliage while it is feeding poison to the plant. But at the same time, I need to contain the spread, so that I may now the lawn. I saw a response to a similar question that suggested pruning prior to applying Crossbow. I've already applied Crossbow and would like to know when I can cut without rendering Crossbow ineffective. Thanks!
Yes, Crossbow Herbicide is still being absorbed in the plant throughout that time period. We do normally recommend that you prune the plant before you apply Crossbow. It is recommended that you wait at least 30 days before pruning the plants once Crossbow has been applied. You can still cut the plant down after application.

We live on a steep bluff and want to get rid of blackberries but do not want to kill native plants. We have been cultivating natural salal and huckleberry, small madrone, and broad leaf Maple.
Crossbow Herbicide could affect desirable woody and viney plants that are sprayed with it. You should avoid spraying desirable vines and trees. We suggest spot treating the target plants and spraying when conditions are calm.

I have some woody plants (small trees) and briars growing in my beds with my boxwood hedge. Will Crossbow also kill the boxwoods if I use it on the woody plants?

The grape hyacinths have multiplied and spread to places I don't want them. Digging them out hasn't been successful because it's impossible to get them all. I'd like to know how to get them gone.
Helena Crossbow Herbicide does not specifically list grape hyacinths. We recommend that you consult with your local cooperative extension office Master Gardener for tips on eradication.
Crossbow Herbicide can be used to kill dormant blackberry bushes and vines. You would apply to thoroughly wet upper and lower stems including the root collar and any ground sprouts. Treat at any time when the brush is dormant and the bark is dry. Best results have been obtained with late winter to early spring applications. You will use 1.5 gals./acre broadcast application or 1 to 1.5% mixture. Please refer to the product label for complete mixing and application instructions.

It's been 4 years since I replanted. The blackberries are going wild. I have 6 acres I cut all the big Douglas fir trees down on. I took out 200 trees and then replanted 1000.
Crossbow should not harm established trees but may damage younger trees if applied directly to them. To avoid injury, do not apply directly on or within the drip line of smaller trees and avoid the foliage and any exposed roots of mature trees. It is best to carefully spot treat the target plants to avoid injury to your desirable trees.

Herb and vegetable gardens were sprayed to kill clover and other weeds. How soon can we pull up weeds? I read that we should wait 3 weeks before planting grass - does that apply to planting herbs, vegs, and flowers?
Crossbow Herbicide is not labeled to be used around anything edible like vegetables. It is also a vegetation management product, which means that it is not very selective, so it will kill almost anything that it is sprayed on, including the edible plants. You will need to wait at least 3 weeks before replanting in areas areas where Crossbow Herbicide has been applied. You will need to wait at least 1 year after application to plant any edibles intended for human consumption. We would not recommended consuming anything from the current plants in the garden and disposing of anything contaminated by spraying.

Unfortunately, chameleon or Saururaceae, h. cordata, is an invasive species that is very aggressive and difficult to control. Because this plant spreads from underground rhizomes, you will not be able to control it by pulling or mowing. I have not been able to find any products that specifically list this plant on the label, and there is very little information from US sources on management of this plant. We would recommend trying RoundUp QuikPro, a non-selective herbicide with two active ingredients, or Southern Ag Brush Killer. These are excellent active ingredients that will damage most plants. You would want to give either product 10-14 days to see results. Be sure to give the plants enough time to die completely before tilling or disturbing the soil where they were growing.

I cleared a woodland edge of japanese honeysuckle, poison ivy, multiflora rose and other assorted undesirables. I would like to spray to prevent them from returning, but I'd also like to plant big bluestem, persimmon and filbert in 2 months. Is that long enough to wait to plant?
Crossbow Herbicide can persist in the soil for up to 1 year You must wait one year after an application of Crossbow Herbicide to plant anything in the treated areas. Otherwise, you can remove and replace the soil with untreated soil. You will need to wait at least 3 weeks before replanting other plants in areas where Crossbow Herbicide has been applied. However, keep in mind that excessive amounts of this herbicide in the soil could inhibit seed germination and plant growth.
Yes, Crossbow Herbicide can be used to kill dormant blackberry bushes and vines. You would apply to thoroughly wet upper and lower stems including the root collar and any ground sprouts. Treat at any time when the brush is dormant and the bark is dry. Best results have been obtained with late winter to early spring applications. Do not treat when snow or water prevent spraying to the ground line. You will use 1.5 gals./acre broadcast application or 1 to 1.5% mixture. Please refer to the product label for complete mixing and application instructions.
