I was in a big box Ag. store this weekend, looking to buy Triclopyr, as we were cleaning up some invasives in the timber, via a stump cut treatment. The salesman didn't advise it, saying it would remain in soil and kill our hard woods. Thoughts?
 
I have heard it is soil mobile and can harm non-target plants. I used it around some hackberry trees last fall that I didn’t mind losing and we’ll see if they leaf out this spring. I chipped the bark on one and it looks green and healthy, so I don’t expect it to have harmed them. I will say I am surgical with my application and don’t drench the plants limiting the volume. That probably helps not to put a bunch of extra down.

Yup, Tordon can move through the roots to non desirable trees. Triclopyr comes in a few varieties (water based vs oil based) in differing strengths also. Water based is better for hack and squirt and oil based better basal bark I'm told. I've tried oil based (the '4' version) on hack and squirt and it failed, only stunting the tree not killing it. These were hackberries done in late July during a dry period. Get the 3 version for cut stump.
 
Yep!! ^^^^^
That’s one big reason triclopyr is being used instead of tordon. Way less mobile in soil.
