What is a preventive measure to avoid phytotoxic injury when applying herbicides?

• A. Be aware of drift while applying
• B. Use no protective equipment
• C. Apply during windy days
• D. Ignore label directions

Answer: (A)

Preventing spray drift is the key to avoiding phytotoxic injury when applying herbicides. Drift occurs when spray droplets move away from the target area because of wind, droplet size, nozzle type and pressure, and application height. The best preventive measure is to be aware of drift while applying: check wind speed and direction, avoid spraying when winds are gusty or above the label’s allowed limits, and use drift-reducing techniques. This includes using larger droplets when appropriate, choosing drift-reducing nozzles, applying at the recommended pressure, and keeping the spray boom at the proper height and distance from sensitive plants. Scheduling applications for calm, stable conditions and using buffers or shielding as needed further minimizes off-target movement. Always follow label directions to ensure correct rate and timing, which also helps prevent injury. Protective equipment protects the applicator, not nearby crops, and applying on windy days or ignoring label directions would increase the risk of phytotoxic injury.
