III. Beet Scab (Oospora scabies Thaxter). a. Appearance of the Disease. The smooth surface of the beet root may often be disfigured by wart}^ or scabb}^ excresences. The texture of these injuries is somewhat corky or spongy, and the larger diseased areas will show that the injury is not entirely su- perficial, but to some extent alters the tissues immediately underly- ing such areas. The frontispiece shows two beets affected in a char- acteristic manner. The disease begins as small irregularities either widely scattered or clustered. In- dividual ones spread in extent, and groups often become united, so that in time it may spread over large areas, or small isolated areas may remain. One often notices a tendency for the scabb}^ spots to be arranged in more or. 62.—Beet Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Cornell University.
