Parts of the head above the points of attack die. The portion of the head that is killed is a total loss, and the general decrease in vigor of the plant results in shriveled, light grains. Upon stalks and leaf sheaths, beginning at the ground and extending over several internodes, the acervuli may be so numerous as to cause blackening. No remedy is known.
