Not common in Western Europe. Cercospora sorghi is usually considered a minor disease, except where susceptible cultivars are grown in areas where wet or humid and warm conditions prevail during the growing period of the crop. Most Cercospora species have teleomorph stages within the family Mycosphaerellaceae (Ascomycota), but no teleomorph is known for Cercospora sorghi.

ERWIAN-5

Pathway not proven. Only one reference found indicating seed may be a pathway. However, seed transmission was not shown in this research. The pathogen was recovered from seed in laboratory tests. Seed pathway may be inferred because seed is a pathway in onion.
