Tordon RTU Specialty Herbicide is a very damaging product to surrounding plants due to it’s active ingredient, Picloram. Untreated trees/plants can occasionally be affected by root uptake of herbicide through movement into the the topsoil or by excretion of the product from the roots of nearby treated trees. We recommend contacting the manufacturer Dow AgroSciences at 800-992-5994 for advice on what to do at this time.

Tordon RTU Specialty Herbicide could be used and is best used on freshly cut stumps and ensuring the cambium area next to the bark gets thoroughly wet.

Since you are treating the stump directly there should be no issue seeding in the area once the stump is killed and removed.
Tordon RTU Specialty Herbicide can also injure the tree as it can travel throughout the limb into the tree itself. It would be best to just cut any limb that you need killed/removed
