I have a lot of oak trees and pasture includes them. If I want to get rid of poison oak or ivy, is amine or ester better? Hand spraying.
how about pasture spraying with Grazon?

I sprayed Ester last spring and it burned a lot of things I didn't mean to get. It burned several things I didn't want to burn. But it done a good job.

Poison Ivy does not necessarily need to grow on an oak. My guess is the cattle will vote for the shade.

Cormac, amine will kill poison oak and poison ivy and is less volatile than ester according to what I have read. Grazon P+D works great in the pasture here-we stay ~60 feet or so away from trees with the Grazon P+D.

Grazon works. With that stuff you want a good surfactant and dont skimp on it.

Only way I can kill a live oak tree is if I circle it and its gets really soaked on the trunk. Post oaks dont need a reason to die... they just do.
