Which equipment is specifically associated with macroinfusion?

• A. A harness of plastic tubing connecting to plastic tees.
• B. A backpack sprayer.
• C. A mist blower.
• D. A drop spreader.

Answer: (A)

Macroinfusion relies on delivering liquid directly into the plant through a dedicated infusion network, so the equipment used is a harness of plastic tubing connected to plastic tees. This setup provides the physical path and connections needed to route the infusion solution into the plant at multiple points, enabling controlled delivery into the plant’s system. A backpack sprayer, mist blower, and drop spreader serve general spraying, aerosolizing, or soil- or surface-deposition tasks and aren’t designed to create the multi-point delivery pathway required for macroinfusion.
