Which statement best describes the relationship between overspray and drift in regulatory terms?

• A. Overspray is prohibited; drift is negligent and should be prevented.
• B. Overspray and drift are both acceptable if they occur unintentionally.
• C. Overspray is allowed if it occurs during daylight hours.
• D. Drift is exempt from enforcement if it lands on private property.

Answer: (A)

Off-target movement of pesticides is regulated to protect people, property, and the environment. Overspray means pesticide lands outside the intended target area, which violates label directions and is not allowed. Drift refers to droplets moving away from the target during application, usually due to wind, droplet size, or improper settings. Regulators expect applicators to prevent drift because it shows improper technique and can cause harm or liability. In this framework, overspray is treated as prohibited, while drift is something that must be prevented through proper equipment, conditions, and application practices. This aligns with how the regulations aim to minimize any off-target pesticide movement.
