Phomopsis stem blight

Seedlings. Infected seedlings become blighted and die. Those that survive have colourless or bright-red to orange cotyledonary lesions that range in size from pinpoints to lesions that cover the whole cotyledon. Small reddish brown streaks, 1.5 cm long, form on hypocotyls.
Stems and petioles. Senescent tissues are covered with minute, black conidiomata, usually arranged linearly on stems.
Pods. Conidiomata are scattered on dry, poorly developed pods. They may also occur on mature pods.
Seeds. Severely infected seeds are shrivelled, badly cracked, and frequently covered by white mycelium. Seeds also may be infected without showing symptoms.
