Anti-Drift Technology Progress of Plant Protection Applied to Orchards: A Review

Agronomy, 2023
In orchard plant protection application, an anti-drift strategy can effectively reduce drift in the non-target area, reduce spray drift in the environment, and avoid spray leakage and overspraying.

The GDS model?a rapid computational technique for the calculation of aircraft spray drift buffer distances [PDF]

, 2004
[Abstract]: A model for predicting the required spray drift buffer distance for a specified off target deposition level is described. The GDS model is based upon Gaussian diffusion and sedimentation of particles originating from an elevated instantaneous
