Which of the following is true regarding a residue?

• A. It refers to harm that may occur over an extended period
• B. It is a type of spray equipment
• C. It is the same as an EPA registration number
• D. It describes a store that sells pesticides

Answer: (A)

Residue is the leftover pesticide that remains on surfaces or treated products after application. The key idea is that these lingering amounts can pose harm that develops over time with repeated or chronic exposure, which is a central concern for health and regulatory standards. This is why proper application, adherence to label directions, and practices like washing produce or observing pre-harvest intervals matter to keep residues at safe levels. It’s not a type of spray equipment, not the EPA registration number, and not a store that sells pesticides.
