Brief Project Summary:

Several different diseases can cause similar symptoms on soybeans. An example of a disease that is easily misdiagnosed as early crop maturity, sudden death syndrome (SDS), Sclerotinia stem rot or charcoal rot in the North Central United States, is soybean stem canker. Symptoms of the disease can include main stem wilting and widespread plant death in areas of a field (Fig. 1). Closer examination of plants often reveals sunken cankers on main stems (Fig. 2). In recent years stem canker and other diseases caused by fungi in the same group, such as pod and stem blight, have become increasingly problematic in the North Central region. Severe stem canker epidemics can occur in wet springs, and...

Information And Results
Project Deliverables

This project will directly benefit soybean farmers in the North Central region by providing them a better understanding of the impact of a disease that has seen a dramatic increase in importance the past several years - stem canker, and improved information on when to expect infection by Diaporthe organisms and what organisms are specifically causing damage to their crop. This information will allow farmers to more accurately apply the appropriate management techniques to maximize return on investment (ROI) when trying to control stem canker and other related diseases. In addition, non-biased fungicide efficacy information will be generated and disseminated.

Final Project Results

Update:
See October 3rd entry for final report

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
