Applying an herbicide solution to the lower 12-24 inches of the stem of a woody plant is what type of treatment?

• A. Foliar spray
• B. Cut stump
• C. Basal
• D. Soil-active treatment

Answer: (C)

Basal treatment targets the lower portion of the trunk. By applying herbicide to the base, typically the lower 12–24 inches of the stem, the product can penetrate the bark and move into the plant to kill it. This method uses an oil-based carrier to help the herbicide seep through the bark, making it effective for woody plants where other methods aren’t practical. It’s different from a foliar spray, which is applied to leaves; from a cut stump treatment, which is applied to a freshly cut surface after cutting the plant; and from a soil-active treatment, which is applied to the soil for root uptake. Therefore, applying the solution to the lower part of the stem is a basal treatment.
