Hutchinson, Kansas
My wife and I just bought a house with a couple acres in Hutchinson Kansas. The soil is very sandy. We have a bunch of wild marijuana and I have identified a BUNCH of poison ivy. My wife and I have been trying to clear the weeds out but after her first day she broke out in a rash basically covering her from head to toe. I've been out there almost daily with 0 rashes. It's gotten out of hand and she's actually had to miss work it got so bad. I've researched for hours but the plants are seem so similar I can't put my thumb on it. Please look at these pictures and if you can identify them or give opinions It would be greatly appreciated! Thank you

That sounds horrible. We do need photos, both of whole plants and close-ups of leaves.
For me, gardening is really just an excuse for playing in the dirt. Admittedly, plants are a satisfying by-product.

#4 and #7 have poison ivy.
If it takes a long time to grow, remember that if nobody plants it, nobody has it.

#3 maybe a River Birch

#5 is Lamb's Quarters. That won't give you a rash - people eat it.

#6, 11 and 12 are Locust trees

#8, 9, 10 could be something like (or related to) cow parsley. That is VERY poisonous.

#13 if its a vine, Virginia Creeper

You and her getting rashes has more to do with a person's sensitivity to poison ivy. Just because you are 100% certain that you know what it looks like doesn't mean that you can avoid it! Accidental exposure happens all the time.
People that have allergies to other members of the cashew plant family make them more susceptible to poison ivy outbreaks.
The allergy comes from an oil within the plant. There is no such thing as a poison ivy immunity. I am HIGHLY allergic! It has more to do with repeated exposure. The first fifty times you are exposed, you have no reaction but it is incident #51 that causes you a mild outbreak. One should always be careful. Learn to ID and stay away.

That first and second look to be giant ragweed, AKA bloodweed. Yes, there are both leaf types, five and three. The pollen is a major allergen, but it's not much of a skin allergen, although it can happen. It is a very aggressive colonizer and a huge nuisance, as it grows very large and spreads like mad. Get on it now with Round-up or similar. It will kill it nicely when it's young. If you can kill it out the first year, you will probably have a light problem next year, but go after it heavy. It and pigweed are my major pests.

I see poison ivy and maybe poison oak and some other stuff that I don't recognize as poisonous. Maybe some Virginia creeper, which is no problem.

Poison ivy also responds to Round-up. You may not be fond of herbicides, but you're not going to make headway against giant ragweed without it, and not against poison ivy without getting intimate with it. Just use a hand sprayed and be a surgical as possible. If the giant ragweed gets out of hand, you'll be out there with a 15-gallon tank sprayer trying to knock it down. There's a lot of stuff on DIY natural things for poison ivy, but in my experience they all take time and commonly don't get the roots.

Giant ragweed is actually easy to pull up, especially out of sandy soil.

Assembling all the answers - see below.

If one is allergic to Poison Ivy - and it's identified in your photos - that is likely your culprit. Contact dermatitis from other species COULD happen, but the suffering is probably related to the Toxicodendron radicans.

1. Ambrosia trifida - Giant Ragweed

2. Ambrosia trifida - Giant Ragweed

3. Celtis occidentalis - Common Hackberry

4. Toxicodendron radicans - Poison Ivy

5. Chenopodium album - Lambsquarters

6. Robinia pseudoacacia - Black Locust

7. Toxicodendron radicans - Poison Ivy

8. Conium maculatum - Poison Hemlock

9. Conium maculatum - Poison Hemlock

10. Conium maculatum - Poison Hemlock

11. Robinia pseudoacacia - Black Locust

12. Robinia pseudoacacia - Black Locust

13. Parthenocissus quinquefolia - Virginia Creeper

And, there you go.
