What are mist-blockers?

• A. Apply a pesticide at a ultra low volume.
• B. Include handheld backpack sprayer.
• C. Can produce 50 to 300 PSI.
• D. Are a type of sprayer with tree injection capability.

Answer: (C)

Mist-blockers are sprayers designed to create a fine spray by forcing the pesticide through a nozzle at relatively high pressure. The key feature that defines them is their ability to reach about 50 to 300 psi, which drives atomization and produces a true mist. This high-pressure capability sets them apart from ultra-low-volume systems, which use much lower pressures and volumes, from handheld backpack sprayers that typically operate at moderate pressures, and from tree-injection methods that deliver pesticide directly into the tree tissue rather than spraying as a mist. So, the defining trait is their pressure range, enabling the fine mist needed for that application.
