Assessment of Spray Drift with Various Adjuvants in a Wind Tunnel

Agronomy, 2022
When pesticides are sprayed, a significant portion of the droplets drifts away from the target. Using an adjuvant in spray liquid is an easy option for reducing droplet drift because there is no need to make any changes to the sprayer.
