Which of the following is NOT a method of controlling woody plants?

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

Answer: (D)

Controlling woody plants here relies on delivering herbicide directly to the plant so it moves through its tissues and kills the root system. Foliage spray targets the leaves, where the chemical is absorbed and translocated to the rest of the plant. Basal application coats the lower trunk so the chemical penetrates the bark and enters the vascular system. Cut stump treatment applies to a freshly cut stump to prevent resprouting. Soil-active treatment, however, applies herbicide to the soil with the idea that roots will take it up from below. This approach is less precise for established woody plants, can affect non-target plants and soil life, and is not a standard method for ROW brush control. That’s why soil-active treatment is not considered a typical method for controlling woody plants in this context.
