Evaluation of Red Crown Rot Management Practices

Evaluation of red crown rot management practices in Kentucky PI: Carl Bradley Plan of work: Red crown rot, caused by the fungus Calonectria ilicicola, was discovered for the first time in Kentucky in September 2021 in soybean fields in Graves County, KY. The disease has now been confirmed in three counties in Kentucky (Calloway, Carlisle, and Graves), and has been shown to reduce soybean yield components by over 50% in Kentucky soybean fields. Currently, little is known about effective management practices for this disease. Field research to evaluate the management of red crown rot with fungicide seed treatments and in-furrow fungicide treatments will be conducted. Results from the trials will be relayed to stakeholders through Extension outreach activities.
