The Triclopyr will kill blackberry and most hardwoods. There’s no reason to apply 2 oz per gallon. That’s a very high application rate.

Thank you for this info! I need to add a lot more glyphosate to my mix from now on.
For grasses you can use half that rate, but for brush control you can actually go up higher than that, but 6-8 oz/gallon works well on brush and vines. The triclopyr takes care of most woody stuff the gly don’t.
