Book excerpt: Soybean production in the Upper Midwest region of the United States is consistently threatened by Sclerotinia stem rot (SSR), caused by the fungal pathogen Sclerotinia sclerotiorum. Management practices for this disease have historically been studied in depth. However, a reevaluation and modernization of these practices is greatly needed. To achieve this, many methods of control are being examined such as the assessment of integrating multiple cultural practices, the reassessment of chemical controls, the development of improved genetic resistance through both classical breeding and reverse genetics, and the integration of resistant genotypes into predictive models. From this research, the optimum cultural and chemical practices were identified for controlling SSR across the Midwest. These practices were examined for their effect on partial profits to understand their economic feasibility. Through breeding efforts, three elite soybean genotypes were identified with high levels of resistance to SSR, and more early-generation breeding lines are being progressed from additional breeding populations. Furthermore, four breeding lines were identified as having differential consistent responses to S. sclerotiorum, and these four lines were established as standardized checks. Using these four check lines, the integration of resistance into S. sclerotiorum apothecial models is being studied to improve predictive accuracy. Collectively, these research efforts will help to modernize management and control of SSR from both research and production perspectives.
