Article: If you’d rather not use chemicals to kill the poison ivy plants, you can make a natural herbicide. Combine 3 lb (1.4 kg) of regular table salt with 1 US gal (3.8 L) of water and bring it to a boil. Stir until the salt is completely dissolved in the water and allow the mixture to cool. Then stir in 2  fl oz (59 mL) of dish soap and transfer the liquid to a spray bottle. You can also transfer the liquid into a bucket and paint it onto the leaves with a paintbrush if you don’t want to accidentally kill other plants. Look for an herbicide that contains triclopyr, 2,4-D mecoprop decamba, or glycophosphate. These are powerful chemical agents that will kill the poison ivy as well as any other plants that you apply it to. The herbicide needs to stay on the plant to work, so don’t apply it right after before it rains. Wait for a clear, dry day to apply the herbicide. Then, spray the plants that you want to kill. Make sure to spray every part of the plant, from the leaves to the roots.  Follow the herbicide manufacturer's instructions carefully to ensure safe and effective use of the product. If you want to protect nearby plants, use a paintbrush to apply the herbicide to each leaf individually. Throw away the paintbrush after you finish using it. It can take multiple applications of herbicide to kill the poison ivy. Check the plants in 1 week, and if they’re not dead, apply the herbicide again in the same way as you did the first time. The plants will turn brown and crumble after applying the herbicide. Rake up the remains of the dead plants and throw them away in garbage bags. Make sure to label the garbage bags to indicate their contents and throw it away with the rest of your garbage. Wear protective clothing while you collect the plant’s remains.

What is a summary?
Mix salt, water, and dish soap for a natural herbicide. Use a chemical herbicide for a stronger option. Apply the herbicide in the spring or early summer on a clear day. Repeat the herbicide application in 1 week if the plant still has not died. Dispose of the plants once they die.
