What things should pesticide applicators be MOST aware of to avoid spray drift?

• A. Droplet size and wind directions and speed
• B. The color of the spraying equipment
• C. Time of day only
• D. The crop price

Answer: (A)

Spray drift is controlled primarily by droplet size and wind conditions. Smaller droplets are lighter and can be carried farther by air currents, increasing drift potential, while larger droplets settle more quickly and are less likely to drift off target. Wind direction and speed determine the path and distance droplets travel; even light winds can push spray toward adjacent areas, and gusts or shifts can change where the spray ends up. To minimize drift, select nozzle types and pressures that produce an appropriate droplet size for the target and crop, and apply only under favorable wind conditions, adjusting boom height and using drift-reducing nozzles as needed. Avoid spraying during atmospheric inversions or when winds are toward sensitive areas. The color of equipment, time of day, or crop price do not influence drift.
