How does tree infusion work?

• A. Tree infusion works by gravity flow: a reservoir hangs from the trunk and liquid is drawn into the tree's uptake system, with pesticide solutions fed into holes in the trunk or root buttresses.
• B. It uses high-pressure spraying to inject into the canopy.
• C. It distributes pesticide by spraying across the soil near roots.
• D. It relies on aerial dispersion.

Answer: (A)

Tree infusion delivers pesticide inside the tree by using a gravity-fed reservoir attached to the trunk. The liquid is introduced through holes in the trunk or near the root buttresses, and the tree’s own uptake system draws it into the vascular system. Once inside, the solution travels with the tree’s sap through the xylem as the tree transpires, distributing systemically to tissues throughout the tree, including the canopy. This method provides internal protection without relying on surface sprays or soil applications, and it leverages the tree’s natural transport to move the chemical to places pests feed. It requires careful insertion and monitoring to avoid damage or disease entry, and it isn’t suitable for all trees or chemicals.
