Duster sprayers apply which form of pesticide?

• A. A fine spray of liquid droplets
• B. A fine, dry layer of powdery mixture containing small amounts of pesticide
• C. A dense fog of liquid
• D. A wet slurry

Answer: (B)

Duster sprayers apply pesticides in a fine, dry powder form. They are designed to distribute dry formulations, sending tiny powder particles into the air so they settle as a light, dry coating on plant surfaces or other target materials. This is different from spraying equipment that creates liquid droplets, devices that produce a dense fog of liquid, or methods that deliver a wet slurry. So the correct form is a fine, dry layer of powdery mixture containing small amounts of pesticide.
