Species Affected:Barley, Barley Grass.
Biology:Survives on Barley residues and probably on Barley Grass residues.
Life Cycle:Wet conditions in autumn stimulate fruiting bodies within plant residues to release spores that infect young Barley leaves. Lesions develop and wind borne spores are released from the blotches late in the season to infect other plants and distant crops. Tiny, black fruiting bodies are produced in the plant tissue before senescence.
Origin and History:Discovered in 1990 in South Australia.
Distribution:South Australia and Western Australia.
Significance:Management and Control:
