What term describes the portion of a pesticide that remains in the environment or on a surface after application or spill?

• A. Residue
• B. Toxic
• C. Pesticide
• D. Translocation

Answer: (A)

Residue is the portion of a pesticide that remains after application or a spill. After applying a product to turf or if a spill occurs, some amount can stay on surfaces, soil, water, or plant material. That leftover portion is what we call the residue, and it matters for safety, disposal, and how long restrictions or reentry rules apply. The other terms don’t fit because toxicity describes how harmful the chemical can be, not how much stays behind; a pesticide is the chemical itself, not what remains; and translocation refers to movement of substances within plants or organisms, not the leftover presence on surfaces or in the environment.
