While current technology allows automatic
control of boom height on many sprayers, until recently there was no way
of controlling yawing movements – that is, the horizontal movements of
spraying booms. Where yawing occurs, spraying booms swing backwards and
forwards in an uncontrolled manner while the sprayer travels across the
field, and chemical applications can vary from very low rates up to four
times the required rate as a result.
