Cut-surface treatments are used to control plants with what characteristic?

• A. Thin bark
• B. Very small roots
• C. Thick bark or trunks larger than 5 inches in diameter at the base
• D. Leaves only

Answer: (C)

Cut-surface treatments work by applying herbicide to the freshly exposed cut surface of a woody plant’s stump, so the chemical can contact the cambial tissue and be translocated to kill the root system. This approach is most effective on plants with thick bark or large trunks, specifically trunks larger than about 5 inches in diameter at the base, because the outer bark blocks other application methods and the fresh cut provides direct access to the vital tissues. It isn’t used for leaves-only plants or for very small plants, where foliar or other methods are more appropriate.
