Frogeye leaf spot (FLS), caused by the pathogen Cercospora sojina, is a common soybean foliar disease of many soybean-producing regions worldwide. In the U.S., the disease is established in southern production regions and has recently become prevalent in the Midwest and Upper Midwest. It’s believed that the range expansion and increased disease severity are caused by widespread planting of susceptible varieties, warmer winter temperatures, and the increased adoption of conservation tillage practices, which, together, lead to increased inoculum levels. FLS does not always cause yield loss, but yield loss of up to 60% has been reported with severe infection rates.
