Which is an advantage of airblast sprayers?

• A. Small amount of water covers large area.
• B. They require no refilling.
• C. They work without wind.
• D. They operate only under high wind conditions.

Answer: (A)

The advantage is that the strong air flow from an airblast sprayer pushes droplets into the entire canopy, so you can achieve thorough coverage over a large area with relatively little liquid. The airstream drives spray into the leaves on all sides, including inner and upper portions, which means you can treat many trees quickly and use less water per tree than some other spraying methods. Refilling is still needed as you work, and wind matters for drift management—airblast sprayers use their own fan, but external wind can still push droplets off target. They are not limited to high wind conditions; in fact, calm to moderate winds are preferable to control drift.
