Plants infected with Cephalosporium stripe have pronounced yellow stripes running the full length of the leaf blade. The center of the yellow stripe may have a long, brown streak that extends onto the leaf sheath. Splitting the stem of infected plants often reveals small, brown streaks within the node tissue. Cephalosporium stripe also can cause areas of stunted, irregular growth within a field. Often, infected plants die prematurely, causing patches of white heads within a field.
