Nice photos, but they actually show it is poison ivy.
However, poison ivy is not an ivy. And poison oak is not an oak. They are both in the same genus, so very closely related. Toxicodendron. Same herbicides work on both.

Middle photo is poison ivy.
Bottom photo shows the differences.
So the pre-2009 study was done with delicate cells growing in a petri dish. They applied high concentrations of commercial herbicide and the cells were injured. Surprise, surprise. POEA is an animal fat/waxy soap and was in the commercial solution so that when the correct dilution was used the herbicide would stick on the leaves. There are 'studies' like this done from time to time by researchers who want desperately to find something wrong with Roundup and the company that created it. So far all those studies have been flawed, like this one that uses crazy high concentrations of something and very delicate exposed cells growing in a petri dish. The important thing to notice is that the herbicide itself did no such damage. Eight plus years later, we can still safely get rid of our poison ivy.
I have ALWAYS questioned researcher's conclusions. I also question the integrity of the researchers
themselves. To whom do they answer? That's why I think Roundup should be banned, taking into consideration your conclusions and those of scientists. Why take the chance, IMO?
Regardless, caution is still the better choice if you are not sure that it is poisonous. One case of PI (never had oak or sumac) has me out hunting from afar in March.
We have poison ivy and osk in the yard and it comes in many many different forms. It has so many forms it's not worth guessing. It's leaves of three and looks a lot like it. That's enough. Do anything you can to get rid of it. Watch youtubes and read up on it. My husband gets it often. Some of it must have gotten on tools and boots because he keeps getting reinfected. Be very careful but get rid of it.
Thanks for all the info. I just got rid of it using a plastic bag and get rid of the bag altogether.
I got it last month and I must tell you I do not want to get in contact to it. It started with a few dots like pimples and then in a week, I got over 100 blisters. No medications help. Surprising, applying toothpaste stopped the itch. They gone in exactly exactly 3 weeks. Whatever you do, do not scratch the itch. If you can, don't even wash the blisters. Washing the blisters make the area itch.
Yes, it is poison ivy. The "disease" is most likely caused by poison ivy leaf gall mites. Wear gloves when you pull it out, and absolutely don't burn the plants -- that's a good way to end up in the hospital.
Poison ivy does not typically have lobed leaves. It does grow in threes, but they are typically a darker green with a sheen from the urushiol. Where do you live? Maybe it varies in your region ?
