Which term describes small droplets produced when an oil-base pesticide is dispensed through a special device that uses heat to vaporize the pesticide?

• A. Fog
• B. Absorption
• C. Adsorption
• D. Drift

Answer: (A)

Fog describes the tiny droplets created when an oil-based pesticide is released through a device that heats the liquid to vaporize it. The heat turns some of the pesticide into vapor, which then cools and condenses into very small droplets that float in the air. This creates a dense, airborne mist—the fog. Absorption and adsorption refer to how pesticides interact with surfaces or organisms, not the form of the spray, and drift is about where droplets move after release due to air movement. So the small droplets produced by heat-based oil-based pesticide dispersion are called fog.
