Which action helps prevent drift by keeping the pesticide where it belongs?

• A. Incorporate into soil as directed
• B. Apply on bare slopes
• C. Use ester formulations
• D. Increase application rate

Answer: (A)

Drift happens when spray droplets or vapors move away from the intended target. Placing the pesticide into the soil as directed physically locates the chemical where it will act and reduces its exposure to wind and air movement. Soil incorporation helps limit volatilization and keeps the product from moving off target with spray or runoff, so it stays where it’s meant to work and minimizes off-target effects. Using the product on bare slopes increases runoff and downslope movement, which can carry the chemical away. Ester formulations tend to be more volatile and drift-prone than other formulations. Increasing the application rate adds more chemical to the area, which can raise the potential for drift and off-target exposure.
