A cultivator including a plow in which a pair of sweeps extend outwardly and downwardly from a plow shank for pushing soil outward from the center of the plow has at least one of the sweeps provided with a vertical vane at an outer end portion thereof for preventing any weed seeded soil from being placed on a herbicide banded area adjacent the path of the cultivator. Where each sweep is provided with a vertical vane, a rigidifying brace may be provided extending between the vanes.
