The image processing and pattern recognition technology of identifying the crop disease are rapid and simple in order to provide the required information by taking measures in time. The paper will use the crop disease based on image segmentation processing centered to utilize the segmentation theory of theshold segmentation and edge detection represented, and the segmentation method by combination of mathematical morphology, fuzzy clustering and specific theory for research. The data shows that
