Volatilization occurs when a pesticide changes from a solid or liquid phase to a gaseous phase. Which option correctly identifies this process?

• A. Volatilization
• B. Absorption
• C. Drift
• D. Calibration

Answer: (A)

Volatilization is the process by which a substance changes from a solid or liquid into a gas. That’s exactly what the statement describes: the pesticide moving into the gaseous phase. Understanding this helps explain why volatilization matters, because when a pesticide becomes a vapor, it can travel with air and affect areas away from the target site. Absorption would mean the chemical is taken into a surface or organism, not a phase change. Drift refers to the unintended movement of spray through the air, which is about transport rather than the chemical changing state. Calibration is simply about setting equipment to apply the correct amount, not about state changes. So the term that best fits the description is volatilization.
