What term describes unused or leftover pesticide?

• A. Used PPE
• B. Contaminated soil
• C. Unused or leftover pesticide
• D. Old labels

Answer: (C)

The concept here is identifying what you call material that hasn't been used up. The term for pesticides that remain unused or left over after stock is kept or after an application is simply “unused or leftover pesticide.” This label matters because it signals that the product needs to be handled as pesticide waste and disposed of or returned according to the label directions and local regulations, to avoid environmental harm and safety risks.

Other items refer to different things: PPE is personal protective equipment, not pesticide itself; contaminated soil means soil that has pesticide residues after use and is a separate waste concern; old labels are outdated instructions, not the pesticide product itself.
