Findings from this project will be shared through the University of Delaware’s Weekly Crop Update which reaches over 700 growers, consultants, and stakeholders and provides a platform to discuss disease concerns and other production issues. Data will also be shared through training events and extension presentations such as Mid Atlantic Crop School, and the 2022 Delaware Ag Week. At University of Delaware hosted field days and commodity meetings, growers will be given a brief questionnaire to better understand concerns regarding nematode management and to investigate knowledge bases surrounding SCN resistance genes. In 2020, the United Soybean Board gave funding to the SCN Coalition to widen its reach to all states as data has shown that resistance gene PI88788, used in >90% of SCN-resistant soybean cultivars, is beginning to lose effectiveness. Dr. Koehler is a member of the SCN Coalition and questions used in this survey may include a set of questions released by the SCN Coalition to understand grower choices, perceptions, and
understanding of SCN host resistance
