Soybean leaf blight incited by the purple seed stain fungus Cercospora kikuchii is reported under field conditions in the United States. Symptoms first appear during initiation and development of seed. Infection of leaves and petioles causes rapid defoliation beginning with the uppermost leaves and moving down. Resistance to the disease varies among cultivars. Fungicides reduce disease loss.
