Question

How do you get rid of poisonous plants?​

Answer 1

It turns out that salt, in high enough concentrations, works to kill most unwanted plants, including poison ivy. But you can't simply sprinkle it around. Create a saline solution by mixing three pounds of salt, a gallon of water, and a quarter-cup of dish soap.

Answer 2

Answer: Hands-on removing the plant.

Explanation: The best way to remove poisonous plants from your yard would be to protect your arms and legs with clothing, and pulling the plant from the ground, along with it's roots. Then you can trash the plants or burn them, depending on the laws of your state/country.
