Vergeer from The Dalles, Or. writes

Best time of year to apply Crossbow Herbicide to poison oak

We have a small forest with spreading poison oak we live in eastern Oregon with common temps above 100 degrees. The leaves are just starting to take on the red tone.

Answer:

Crossbow Herbicide is a post-emergent that targets actively growing and visible woody brush and plants.  You can apply it per the labeled instructions once the poison oak is visible. Please keep in mind to protect desired pants from overspray or drift, as it may injure others that it may come in contact with.
