What is a potential disadvantage of ULV sprayers?

• A. Increased risk to applicator from handling and spraying concentrated pesticide.
• B. Reduced exposure risk.
• C. No safety concerns.
• D. They are safer to handle than other sprayers.

Answer: (A)

The key idea is safety and exposure risk with ULV (ultra-low volume) sprayers. ULV systems spray very fine droplets to cover large areas with a small amount of liquid, which means formulations are often more concentrated. Handling and spraying these concentrated pesticides can increase the operator’s exposure during mixing, loading, and application, especially if precautions aren’t strictly followed or PPE isn’t used correctly. The fine droplets also drift more easily, which can raise exposure risks to the applicator and people nearby. So the main disadvantage is the higher risk to the applicator from handling and spraying concentrated pesticide. The other statements suggest reduced risk or no risk, which isn’t accurate for ULV sprayers.
