Which factor most influences drift potential during spraying?

• A. Wind speed and direction
• B. Soil type
• C. Temperature
• D. Humidity

Answer: (A)

Drift potential is all about how air moves the spray droplets. The wind carries droplets away from the target, so the faster the wind and the specific direction it blows, the farther those droplets can travel and the more off-target drift you’ll see. While temperature and humidity can affect droplet evaporation and size, they don’t push droplets off-target as much as the wind does. So the primary factor shaping drift during spraying is wind speed and direction.
