In order to do the research on the influences of the parameters on spray drift, measurements of the drift potential under different wind tunnel conditions were made for different typical nozzles. The results showed that smaller type nozzle, larger spray pressure and wind speed could enhance the drift sensitivity along with the change of spray height, and the sensitivity of LU nozzles was more obvious than ID nozzles. Relative to the wind speed and nozzle type, the spray orientation has an inapparent influence on spray drift.
