Which factor is NOT a component of weather conditions affecting drift performance?

• A. Tank color
• B. Wind speed
• C. Droplet size
• D. Temperature

Answer: (A)

Drift is influenced by both weather conditions and spray physics. Wind speed directly pushes droplets across the landscape, increasing how far they travel from the target. Droplet size matters because smaller droplets stay suspended and carried by air currents more easily, making drift more likely than with larger droplets. Temperature affects air density and evaporation; warmer, drier air can cause droplets to evaporate into smaller forms, again influencing drift behavior. Tank color, on the other hand, has no impact on how droplets move through the air or on evaporation and drift dynamics. It’s just a cosmetic/material attribute of the sprayer tank and does not change the physics of drift.
