Brief Project Summary:

Southern stem canker is a relatively new soybean disease in North Carolina. In 2015, this disease severely affected whole fields on at least two farms and developed much more rapidly than expected. In one case, it expanded from one field to several fields on several farms in the same neighborhood. In both cases, the disease appeared early enough during reproductive growth that yields were probably significantly reduced. This on-farm research intends to verify resistance to southern stem canker claims of several soybean varieties, and to determine if disease symptoms are similar among several varieties. It will also provide training and support to learn more about this disease.

farmers, agronomists, extension agents

Information And Results
Final Project Results

If 1% of NC soybean farmers switched 5% of their acreage from a variety susceptible to stem canker to a variety resistant to stem canker, and 1% of that acreage got stem canker, farm gate profits would be increased by $8,000, and checkoff income would be increased by $40. More importantly, we will learn whether the stem canker biotypes do or do not coincide with the advertised claims of stem canker resistance, especially for the 15 most widely recommended Glyphosate Tolerant varieties available in the state.

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.
