Description

Each year, soybean growers lose at least 14 percent (approximately $175,000,000 in Indiana) of their crop to disease. Root rots disease caused by particular species of Fusarium, Phytophthora, Rhizoctonia, Phialophora, and Macrophomina account for a significant portion of this annual yield loss and substantially increase yield losses above 14 percent in specific production areas in the Midwest. Yield losses due to diseases like Fusarium root rot, Phytophthora root rot, Rhizoctonia root rot, Brown stem rot, and Charcoal root rot caused by species of the fungi mentioned above have been recognized for a number of years and most soybean producers are somewhat familiar with disease symptoms associated with each disease. However, root rot damage and losses due to Sudden Death Syndrome, a relatively new soybean disease are not as well documented.

Factors Influencing Sudden Death Syndrome and Root Health in Soybean
