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.

Over the past few seasons, soybean yields as a whole have been pretty impressive. As a strategy to combat lower grain prices, many farmers are taking a closer look at soybean after soybean, or even continuous soybean, rotations. This is especially true for farmers with acres that may not always be best suited to grow corn. Some things to think about when considering a soybean after soybean scenario are fertility, disease management, planting rate, and weed control.

Frequent rains have made the 2015 growing season very challenging. Yellow corn and soybeans are something many farmers in Ohio are tired of looking at. As I’ve walked fields, I’ve seen increased disease pressure in corn and soybeans that came in even earlier than last year. These include gray leaf spot, northern corn leaf blight, and anthracnose in corn and frogeye leaf spot and septoria brown spot in soybeans. In many fields, disease was of secondary concern due to water damage and nitrogen loss.
