A field spraying device for spraying a liquid on a crop, includes a liquid supply tank, at least one spray boom extending from the device, the spray boom having a forward side facing the directional movement of the field spraying device in operation and an opposing rearward side, wherein the boom includes a liquid supply line connected to a plurality of nozzles along the length of the boom for spraying a field with the liquid. Further, there are a plurality of wind drift spoiler devices wherein each wind drift spoiler device is position adjacent each of the nozzles on the forward side of the spray boom. The wind drift spoiler devices include a downwardly depending deflector surface adjacent each of the nozzles. The wind drift spoiler device may also be equipped with a downwardly depending brush element, wherein the brush element is positioned to depend downwardly from the deflector surface.
