In a tree injection system, what is the recommended approach?

• A. Use high pressure to force uptake
• B. Inject into leaves only
• C. Do not use uptake
• D. Use low pressure and allow uptake

Answer: (D)

Tree injection works best when the chemical is taken up by the plant's vascular system rather than forced in. Using low pressure and allowing uptake lets the product move with the xylem as the tree draws water and nutrients, giving safer, more uniform distribution. High pressure can damage bark and cambium, cause tissue injury, and lead to erratic movement of the chemical. Leaves are not the proper target for this method, which is designed to enter through the trunk or root-flush to reach the vascular system. Therefore, the recommended approach is to use low pressure and allow uptake.
