Definition of a deposit includes which of the following?

• A. A pesticide remaining immediately after an application.
• B. When two pesticides may not be synergistic.
• C. When two pesticides are blended and then applied.
• D. The area to be evacuated.

Answer: (A)

Deposit refers to the pesticide residue that actually stays on the target surface after the spray is released. So describing a pesticide remaining immediately after an application captures the essence: it’s the portion that remains on leaves, soil, or other intended surfaces to provide control. The other options point to different ideas—the interactions between pesticides, the act of mixing and applying, or safety evacuation areas—none define what deposit means. In practice, understanding deposit helps you gauge coverage and potential environmental impact, and it’s influenced by factors like nozzle type, droplet size, application pressure, weather conditions, and the target surface.
