What is the primary mechanism of an airblast sprayer?

• A. It carries pesticide and water under pressure through nozzles into a blast of air produced by a fan.
• B. It sprays pesticide as a fine mist without air support.
• C. It uses gravity feed to deliver pesticide directly to target leaves.
• D. It relies on a handheld sprayer with no fan assistance.

Answer: (A)

The primary mechanism is pushing the spray through nozzles and mixing it with air from a powerful fan to create a spray cloud that penetrates the crop canopy. The fan-produced air blast carries the droplets deeply into the foliage, improving coverage on both the upper and lower leaf surfaces. This combination of nozzle atomization with an air-assisted flow is what sets airblast spraying apart from systems that rely only on pressure or gravity, or from handheld sprayers without a fan.
