- Crop dusters have been grounded for fears of a biological attack.
- The nozzles in crop dusters are best suited to discharging relatively large particles--100 microns in diameter--not tiny 1-micron specks of bacteria.
- The dusters have been allowed back up, but are not allowed to take off or land from what traffic controllers refer to as Class B airspace, or the skies around major cities.
