best way to kill multiflora rose

I have a chunk of woods full of this stuff. Last 3 years I have sprayed the leaves with Remedy; kills off the leaves in summer but keeps coming back. Have heard of spraying with diesel fuel with Remedy on the base of the plant. Is this permanent? Can I do it now before it flowers? If not this, what is the best way to get rid of the stuff?
 
I have used a tractor loader and pushed it out. It is very shallow rooted and easy to push out. Piled it and burned it.

If you want to spray it, Hyvar works very good.
 
MANAGEMENT OPTIONS
Mechanical and chemical methods are currently the
most widely used methods for managing multiflora
rose. Frequent, repeated cutting or mowing at the
rate of three to six times per growing season, for
two to four years, has been shown to be effective
in achieving high mortality of multiflora rose. In
high quality natural communities, cutting of
individual plants is preferred to site mowing to
minimize habitat disturbance. Various herbicides
have been used successfully in controlling
multiflora rose but, because of the long-lived
stores of seed in the soil, follow-up treatments
are likely to be necessary. Application of
systemic herbicides (e.g., glyphosate) to freshly
cut stumps or to regrowth may be the most
effective methods, especially if conducted late in
the growing season. Plant growth regulators have
been used to control the spread of multiflora rose
by preventing fruit set.
 
Not sure if it is legal, but a mixture of roundup and 2,4d, LV4 mixed together in the sprayer along with a heavy dose of dish soap seems to work quite well. And a good dose of either blue or red dye (laundry department at stores) makes it easier to tell where you have sprayed.
 
Try Tordon RTU - its the formula that you put directly on the plant. Dont get too carried away cause it can kill trees if you get alot on the soil. The active is picloram. 99% chance it'll get it - but follow the directions - and do NOT get the 22K formula and try to broadcast -- you will have dead trees - for along time. The RTU is designed to kill the plant - some will get excreted out of the roots - so any other small shrubs may get injured.
 
I walk with a spade and some thick gloves and pull the little ones out in the spring. If you slice off the main root at around 6" down and pull the rest out with the little roots, they don't come back. I use my bulldozer on the bigger ones. I've had some growing where it was too steep for the bulldozer so I built brush piles on them and burned them. That was just last year though, so I wont be surprised if they're back in full force next spring. Even if you kill them all on your property, the darn birds will bring them right back in. You have to be vigilant. It only takes 30 seconds to kill a young one.
 
Be very careful with picloram. It has an extremely long half-life especially when underground (especially in the water table). You want to apply it very sparingly. I use a paint brush and just hit the freshly cut stems/stumps. The power company broadcasts it from helicopter on their large transmission lines here, but I wish they wouldn't. Can't really do anything with the roses except broadcast since you can't get in there to cut them off unless you're using a dozer anyway. If you have a dozer, you don't need it.
 
Yep a strong does of roundup is what I use, try and get all the leaves covered it will kill em and they have not come back on me.
 
I second the Tordon RTU option. I cut the cains close to the ground and applied it directly to the cut ends using a small brush. These were long established bushes in a hay field. One treatment and they never came back.
 
You can get great control/kill with Grazon P@D in the spring just after it fully leafs out. Had several pastures we took over that were neglected and full of rose and thistle and we boom sprayed with Grazon and all thats left is grass. Only place we didn't get total kill was where we couldn't spray. No grazing restrictions either.
 
Goats yes goats they love the stuff,like candy to a child. Neighbor had a timber full of it got a handfull of goats, it is gone and the timber is spotless
 
I've successfully killed many type of shrub by cutting, then painting the fresh stump with mix of Roundup and diesel. Dipping a freshly cut blackberry cane in straight roundup will kill it, root and all.
 
Sheep as well as goats love the stuff. Neighbor had a patch. He turned in some sheep and it was gone very quickly.
 
grazon p&d works the best i've seen on what we call rose hedge in my chunk of Tejas...county west of me has about 1/5th of it covered with that mess...some rancher heard it made a good natural fence and planted it and it took over.

Never used the soap, but 2 doses of the chemicals a month apart does the job nicely.

dding the dish soap helps break down the oil on the leaves, so it penetrates better. Hardly ever need a second round.
