Frogeye leaf spot is a disease that can impact soybean yields across this eastern Corn Belt.. Typically, more prevalent in the southern growing regions, the disease can occur farther north as a result of weather favorable to its development.
The fungus that causes Frogeye leaf spot (Cercospora sojina) survives in infected plant debris and can cause infections in growing plants when weather conditions are favorable. Frogeye leaf spot lesions produce spores that are easily transported by wind, acting as inoculum for leaf infections on other plants. The disease is promoted by warm, humid weather and will continue to develop on infected plants during patterns of favorable weather. With the warm and wet weather patterns that have existed in the eastern Corn Belt during 2017, it is expected that frogeye would be observed in some fields.
Frogeye leaf spot symptoms begin as small yellow spots that become larger lesions with gray centers and dark reddish-purple or brown borders.… Continue readingRead More »
