Pathogen

Hosts

Barley

Symptoms

Pale green lines are seen running the entire length of the leaf. These stripes thicken and become yellow eventually turning brown. Ears often become infected and do not fully emerge.

Development

The inoculum comes solely from infected seed which grows internally in the affected plant. Healthy seeds are infected when spores from infected ears are spread by the wind prior to harvest.

Favourable Factors

Cool, below 20C.

Importance

The disease is specific to barley. Yield loss is rarely economic but low levels of infection can lead to rejection of seed for certification.
