Barley stripe
Pyrenophora graminea

Pyrenophora graminea is the causal agent of barley stripe. Barley stripe is disease of barley.

Disease symptoms
Severe seedling infection can cause stunting and post-emergence death, but symptoms are not usually apparent until later, when long, chlorotic or yellow stripes on leaves and sheaths appear. Most leaves of a diseased plant are usually affected. Dark brown streaks develop later in the stripes, which eventually dry out and cause leaf shedding. Ears may not emerge or be deformed and discoloured. Grain production by infected plants is severely restricted.
