Befall mit Pseudocercosporella herpotrichoides, Foto: ISIP
- Bereits im Herbst zunächst an den äußeren Blattscheiden unregelmäßige Verbräunungen, gelegentlich schon in Form eines Augenfleckes
- An jungen Pflanzen kann gesamte Blattscheide verbräunen
- Ab Beginn des Schossens am Halmgrund Bildung der typischen Augenflecken (hellbrauner undeutlicher Rand, helles Fleckinneres)
- Im Halminneren dichtes weißgraues Myzel
- Starker Befall führt zu Vermorschung des Halmes und Abknicken an den Befallsstellen
- Nesterweises Auftreten
- Weißährigkeit, zufällig im Bestand verteilt
