Stand establishment and seedling damping-off have increased in occurrence and severity over the past decade in Ohio. The high incidence of soybean seedling diseases can result in direct economic losses through reduced stands and, in severe cases, the added costs of seed for replanting and reduced yields due to later planting dates. Seedling diseases in Ohio are most prevalent in poorly drained soils with high clay content. These diseases can also occur on better drained soils following heavy rainfall events (<2” at one time). These soil-borne pathogens can be found in most agricultural soils throughout the state.
