Tree injectors are used to

• A. Apply pesticide to leaves
• B. Use to precisely put pesticide into the trunks of larger brush or trees
• C. Spray a broad area
• D. Open soil mixing

Answer: (B)

Tree injectors are designed to deliver pesticide directly into the tree’s vascular system through the trunk. This method provides a targeted, systemic treatment for pests or diseases in large brush or trees, especially when spraying isn’t practical due to size, drift risk, or sensitive surroundings. The chemical moves within the tree to where it’s needed, while minimizing exposure to non-target plants, people, and the environment. Using injectors to apply pesticide to leaves would be a foliar spray, not trunk injection. Spraying a broad area isn’t precise and doesn’t involve the tree’s internal transport system. Open soil mixing involves incorporating pesticide into the soil, not injecting it into the trunk.
