What can you spray on the poison oak plant to kill it?
Herbicides that are effective for killing poison oak include glyphosate (e.g., Roundup brand) and triclopyr (e.g., Ortho brand). You can apply herbicide to the stumps of cut plants or to the foliage of uncut plants, but both must be done while the plant is actively growing. For the first method, cut the stem 1 to 2 inches above the ground and apply the herbicide immediately, using a spray tank. The fresh wound will suck in the herbicide, transporting it deep inside where it can do its damage. Applying herbicides to the leaves of poison oak is most effective during the flowering stage (using triclopyr) or fruiting stage (using glyphosate). Spraying the foliage must be repeated until the poison oak is fully eradicated.
