You spent a ton of time last fall cutting out all the unwanted trees from your fence lines and pastures only to have them come back this year. Cutting trees down still leaves a massive root structure that you have to kill to keep the trees from regrowing.
Corteva – Tordon RTU Herbicide kills cut stumps on fence lines & pastures. Control unwanted tree regrowth. It keeps more than 20 woody species at bay. It translocates into the tree’s root system to stop resprouts. Just apply to the cut stump with the convenient squirt bottle applicator. The blue dye in it lets you easily keep track of treated stumps. No mixing or measuring is required, and you can use it nearly year-round
Unless you get all the roots, pulling or digging the roots can still result in regrowth.
