Abstract

Frogeye leaf spot of soybean, caused by the fungus Cercospora sojina, causes damage in warm, humid soybean-growing regions and has been more important in southern states than in Iowa. Recently, however, the incidence of frogeye leaf spot has increased in north central states, including Iowa, with reports of severe damage in several areas. Symptoms of the disease include small, gray spots with reddish brown borders forming on the upper leaves in mid- to late August.
