The'appearance of the disease im- mediately recalls that of various scab diseases, such as those of fruit trees. The actual damage caused by the disease is not great since only the smaller bottom leaves, mostly "sand leaves", are affected, and in curing, the blotches become less distinct on a brown background. Moreover, it probably never occurs except during exceptionally wet years, such as the 1938 season, or in very wet parts of the field. In other states, but not here, blotch is reported as a seedbed trouble where it may exhibit a variety of symptoms ranging from a slight browning or girdling of the stem to damping-off and wet rot in severe cases.
