Use Any Method to Control Plants
Myth. Don't burn poison ivy, oak, or sumac. Particles of urushiol remain in the smoke and can aggravate your eyes, nose, and respiratory tract, and can land on the skin. Instead, dress appropriately and dig out the plants, getting as much of the root as possible. Put them in a plastic trash bag and throw it away. Have someone else do this if you're super-sensitive to the plant. Some plant killers may work. Read the label carefully and use it at the right time of the year. Be careful -- urushiol remains active, even on dead plants.
