We use Roundup, but not the premix. The concentrate says to use 6 ounces per 1 gallon but I have found that doubling this kills off both leaf and root of poison ivy and poison sumac.Roundup will kill it. Kills poison ivy too. First application might not kill either one because they have root structures underground. But keep after it, and you’ll get it.
If, however, you don’t want to kill other plants (like grass) around it, use a mixture of Remedy and Grazon-Next, half and half, with a surfactant to help it stick to the leaves.
Remedy and Grazon-Next won’t kill grass unless used wildly excessively, but they’ll kill any broadleafed plant, usually with the first application.
Good luck!![]()
