A rotary atomizer suitable for spraying crops with liquid in the shape of a hollow truncated cone having a toothed periphery and internal radial grooves has asymmetric teeth, one side of each tooth being radial and the other side of each tooth being disposed at an angle, preferably 30 DEG -60 DEG to the radius. The grooves lead to the gaps between teeth and may be similarly assymmetrical. The atomizer is unidirectional being rotated so that the radial teeth edges are the leading edges. It may be used singly, or as a stack of cones.
