I figured I'd see some push-back here. Roundup is NOT bad, but poison ivy is. Roundup is one of the most environmentally safe controls you can use on PI. If you had a science background, you'd probably understand the issues a bit better.

I will not engage in a debate on so called "negatives" of the stuff, since frankly, I "don't have the faith" in so-called "organic" or "environmentally sound" alternative or solutions. I prefer approaches that actually work without damaging the soil, like vinegar and detergent can do. You do know that detergents are totally artificial compounds that don't always degrade gracefully?

Round up herbicide works well to stop young poison ivy like this. Spray it on a not-windy day directly on the leaves and in less than a week the plant will starve out. If the spray gets on the soil it will be inactivated, so no problem there. If it touches the thick bark of a tree it will do nothing, so again, no problem. Meanwhile, Round Up will have no effect whatsoever on animal life. On the other hand, most people are miserable if they get poison ivy oils on their skin.

This is one of the best sources of info on PI that I have found. DH and I are both very sensitive to it.

Yeah. Problem with that is I am now so gun-shy I am going by that old saying. Tromped around the woods off and on for 60 plus years and never thought about it till I finally got dosed. I always thought it was some little rash people were freaking out about. NOT! It's blisters like you got burned.

I use those old Walmart and grocery store sacks to pull these up so I don't have to touch it. My yard is only four years old so no established plants and I try to keep it that way.

"Last month, an international agency declared glyphosate, the primary ingredient in the popular product Roundup, a “probable human carcinogen.” The weed killer also has made recent headlines for its widespread use on genetically modified seeds and research that links it to antibiotics resistance and hormone disruption. Several national governments are planning to restrict its use, and some school districts are talking about banning it."

But if you knew the science behind it and the huge amount of research to the contrary, you would question those conclusions. TONS of data say it is okay. If it was a carcinogen there would need to be a molecular mechanism by which it works like that and there is none.

Round Up Poison Ivy Killer. Nothing else works on mine. "Oh but Round Up is evil!" Mom gets severe reactions to it, so that's definately worse. I've used it for seven years and this is the first year that I haven't seen any on the property. It kills that bamboo-like scurge my area has as well.

Where PI is concerned, you must kill the roots and they go very deep. I never thought I'd get rid of mine. Birds distribute the seeds, so i may see it again next year.

NEVER burn PI. The oils get in the lungs and can be fatal. Where long sleeves and gloves, put in plastic bags and dispose. No composting. Throw the gloves away. Heck, through the shirt away too.

Soap and vinegar damage the soil so I only use those on lesser weeds and only on the leaves.
