Looks like either grape or porcelainberry vine, the latter a very invasive pest. Just keep mowing so it doesn't set berries.

Looks like grape vine. It's invasive too. It'll wrap around everything.

Leaves of three let it be

Old post - but that isn't Poison Ivy. Seedling grape imo.

Wild grape, big time invasive. It will choke out trees. I know It has taken over a yew I have in my back yard, unfortunately, it is on a property line. So the neighbor and I would both have to eradicate it. I don't want to argue with the neighbor, or remove the yew that is harboring the ivy's roots and little leaves. I have gone as far as an all-out assault on the Ivy with ROUND_UP . It is our best available weed killer. And it killed nothing. Good that the yew lived. Maybe the neighbor and I can trim back the yews pretty aggressively, and get those vines out, but, I think, easier said than done.

"Roundup is the first part of the chemical makeup for Agent Orange."

No, it's not. Chemically it has nothing to do with it. Agent Orange was a mix of phenoxy growth regulators. Glyphosate is a phosphonate inhibitor of the shikimate pathway. Saying they have anything to do with each other is like saying "please don't eat sugar, it's related to chloral hydrate so it will cause drowsiness and possibly death."

Well sir, I guest we will agree to disagree, or not.

According to the CCOHVA Children Of Vietnam Veterans Health Alliance it i the first part of making Agent Orange by Monsanto. If you are a chemist than so be it. I will never use it. P.S. The VA does not dispute this. Do you use it for it's intended purpose and it does not concern you. Enjoy!

Agent Orange was: 2 4 5 T and 2 4 D, no glyphosphate. Problem was, the 2 4 5 T was contaminated with digoxin.

Most of the Agent Orange problems are attributed to digoxin.

I am aware of that. I don't understand the defending of what is, a poison. Is it dangerous to humans, when it is put in the wrong hands. Monsanto is dangerous to humans. They have been helping block the GMO notification to the public.

"I don't understand the defending of what is, a poison."

The dose makes the poison. By all means, eat organic food to avoid glyphosate in non-organic foods, a route that leads to far, far more human exposure than using it to kill weeds in a home setting. If you are so worried about it. I'm sick of the pseudoscientific hysteria over any "chemical" applied in a garden setting. Many of which have been better tested for safety than the flavorings and colorings used in children's candy.

BTW I personally think Monsanto is a morally dubious company but this has nothing to with this topic anymore, now that generic glyphosate is available on the market. I wouldn't buy roundup brand because the generics are cheaper. Roundup was sufficiently tested to use as a garden herbicide: don't spray it on yourself, on your food, or ingest it, and you will be ok. The surfactants sometimes added to it, can be harmful to amphibian life etc., so when I spray near my pond I use an appropriate aquatic-application approved form of it.

PS the contaminant in agent orange was TCDD, a dioxin. not digoxin, a heart medication.

I agree 100% with david and jim - there is NO relationship between RoundUp (glyphosate) and agent orange (2,4-D and 2,4,5-T).

fyi, ANY pesticide is considered a "poison" to something - that's why they are called pesticides :-)) But as previously noted, most have gone through a very rigorous testing program and if used properly according to label directions, most will have little to no impact on humans or other mammals and minimal other environmental impacts. If we didn't have any pesticides, we would be over run with insect and disease issues and all crop production - the food we eat - would be seriously curtailed.

The OP was asking about if a PLANT was poison, it snowballed from there. I brought up Roundup to kill those weeds.
