How does mist blower spray coverage at very low volumes compare to airblast sprayers?

• A. Coverage with very low volumes may be less than normal volumes delivered by airblast sprayers.
• B. Coverage is always greater with mist blowers.
• C. Coverage is the same as airblast sprayers.
• D. Coverage is always poor with mist blowers.

Answer: (A)

In very low-volume mist blower applications, the total amount of spray reaching the target surfaces is usually much smaller than what an airblast sprayer delivers at its normal operating volumes. Mist blowers rely on a fan to carry extremely fine droplets, but because the overall liquid volume is so low, there’s less chemical mass depositing on leaves, especially inside dense canopies or on shaded undersides. Airblast sprayers, on the other hand, push larger volumes of liquid with a strong air current, helping droplets reach and deposit on more surfaces throughout the canopy. So, coverage with mist blowers at very low volumes is often less than the coverage you’d get from an airblast sprayer operating normally. The other options either claim mist blowers always give greater coverage, equal coverage, or always poor coverage, which doesn’t reflect how volume and airflow influence what actually deposits on the target.
