Which statement best describes wind speed guidance for turf pesticide applications?

• A. Apply within label-specified wind speed ranges
• B. Wind speed is not a factor if using drift reducers
• C. Apply only when wind toward workers
• D. Apply only with wind speeds exceeding 20 mph

Answer: (A)

Wind speed guidance focuses on following the label’s specified wind speed range for turf pesticide applications. This range is set to balance drift risk: there needs to be enough air movement to keep droplets from settling where they shouldn’t, but not so much that they are carried far off-target. The label defines the acceptable wind speed at the height of application, so you should spray only when the wind is within that window. Drift control additives help reduce drift, but they do not override the label’s wind speed requirements, so bad wind conditions still mean no application. It’s also unsafe to spray when the wind could blow toward workers or when wind speeds exceed what the label allows, since high winds typically increase drift and worker exposure. In practice, check wind speed and direction at the application height and delay spraying if conditions aren’t within the labeled range.
