Poison ivy vine control.......

[chrisexv6]

Recently started clearing an overgrown portion of my back yard. I knew there was PI back there, and now I know there is a fairly decent diameter PI vine growing up a tree.

What should I do to kill it? I notice there are a bunch of shoots coming out of the same root as the vine.

I started by cutting the vine open with loppers (in full garb, I looked like a nut!) and painted on some Brush B Gon concentrate (8% Triclopyr).

Is there a better product to use?

How long before reapply the product (either a new product or more Brush B Gon)?

I also have some general vine type weeds that are growing, would the Brush B Gon be the best for those as well? Im guessing I can actually dilute it for those.

Thanks in advance.

As long as the vines are already cut and painted with an herbicide you may be fine. I have always seen a good dose of glyphosate (Roundup) do the trick. Mix at the recommended strength and spray the new growth until there is no more new growth.

You may have to treat a few times. For me one treatment on smaller vines was all that was needed.

Thanks for the info.

I was debating glyphosate vs triclopyr. It seemed half and half, some people said gly and some people said tri.

Also, would cutting into the large vine and painting it affect the "shooters" that are in the ground? Id love to be able to wipe out the whole thing.

The glyphosate will kill anything green it touches so to kill the shoots you will have to spray all leaves unless the shoots are coming off the main plant. I would treat, wait a week and treat again.

Am I better off with glyphosate or triclopyr?

I used tri. 2 days ago, next week I can use tri. or will go out and buy some RoundUp.

I cut the vine and paint straight concentrate Round-Up on the wound leading to the soil. Wait a year or more before pulling the dead stuff out, and clean tools really well, as that oil stays around a long time

If you have a local Lesco (John Deere Landscapes) Pick up some Razor Burn...Stuffs great

We do have a local Lesco, I will check this out.

I noticed the only difference between this and RoundUp concentrate is that the Lesco stuff has added "diquat dibromide", which looks to be a dessicant.

Does that active ingredient help a lot?

this is exactly the right advise. i have used this technique on a variety of plants, including oak, privit and gum. all that is needed is a band of spray around the cambium layer. i have had good luck with a 50/50 mix of glyphosate concentrate and water. handle the foliage carefully as it can cause problems for several years after it is killed. i would add, if you burn the vines, do not breathe the smoke, and clean the cutting surfaces of your tools with alcohol or gasoline to remove the oils that contain the chemical which cause the itch and irritation.
