Where should herbicide be applied in a cut stump treatment?

• A. Around edge of tree and root flare.
• B. In the soil surrounding the tree.
• C. In the trunk of the tree.
• D. Paint entire stump with the application.

Answer: (D)

The key idea is that a cut stump treatment must contact the freshly exposed cambial tissue so the herbicide can be absorbed and translocated into the stump and roots to prevent sprouting. Painting or brushing the entire exposed surface of the stump with the labeled herbicide ensures every part of the cambial area around the cut is covered, giving the herbicide access to the vascular tissue needed for effective uptake. Applying herbicide to the soil around the stump won’t reach the living cambial tissue, and applying into the trunk or only on part of the surface won’t provide uniform contact. Coating the whole cut surface right after cutting maximizes effectiveness and supports proper translocation to suppress regrowth. Always follow label directions and apply promptly while the surface is fresh.
