Can airblast sprayers be used for herbicides?

• A. Yes, with proper calibration
• B. Sometimes, depending on crop
• C. Never
• D. Only for granular formulations

Answer: (C)

Airblast sprayers deliver a powerful airstream that carries droplets into the canopy and can result in extensive drift and off-target deposition. In ornamental and turf settings, herbicides usually require precise, targeted application with equipment that minimizes drift and protects nearby plants. The spray pattern and droplet sizes produced by an airblast setup are not appropriate for safe, label-compliant herbicide use around ornamentals and turf, and many products are not approved for use with this type of equipment. For these reasons, airblast sprayers should not be used to apply herbicides. Always follow the product label for approved application methods.
