Abstract: A cross-flow spraying method comprising creating an air stream by a fan, spraying a crop with a spray liquid injected into the air stream and passing the spray airborne by the air stream across the crop, receiving some at least of airborne overspray in a suction hood located at the lee side of the crop and recirculating the spray liquid. The air outlet from the suction hood may be redirected to the inlet side of the fan, or the suction hood may have its own exhaust fan, and surfaces which precipitate the spray liquid. By utilizing suction as well as pressure, the leaves of vegetation flutter and become more fully covered with the spray liquid. Loss of liquid due to overspray is reduced.
