Driftable fines refer to droplets within which size range?

Driftable fines are classified as droplets that are small enough to be easily carried away by the wind during aerial application. The correct size range for driftable fines is from 50 to 200 microns. Droplets within this range are particularly susceptible to drifting due to their lightweight and small size, making them often the target for mitigating drift in aerial application practices. Understanding this range is important for applying pesticides effectively while minimizing off-target movement and potential environmental impact. The knowledge of driftable fines plays a crucial role in selecting proper application technology and methods to ensure precision and safety in aerial pesticide applications.
