Mist-blockers can produce which pressure range?

• A. Can produce 50 to 300 PSI.
• B. Apply ultra low volume.
• C. Include handheld backpack sprayer.
• D. Used for irrigation only.

Answer: (A)

The key idea is that producing a fine mist from a spray system requires operating at a specific high-pressure range. Mist-blockers are designed to atomize liquid into a fine spray, and this typically happens when the system is delivering liquid at about 50 to 300 psi. At pressures in this range, droplets are small enough to form a true mist and provide good coverage, while still allowing the equipment to function effectively and safely.

The other statements don’t describe the pressure aspect: ultra low volume is about how much liquid is applied, not the pressure; a handheld backpack sprayer is a type of applicator, not a pressure range; and being used for irrigation only isn’t accurate for mist-blockers, which are used for targeted spraying in pesticide applications.
