Brief Project Summary:
With the record-setting warm winter, research predicts residue-borne diseases will be an issue. Thus, the first objective of this project is to survey and monitor the pathogens that affect soybean. Second, evaluate genetic changes and fungicide sensitivity in these populations. Host resistance is the most effective tool to manage these diseases. Resistance to these soil-borne pathogens was identified, as well as more than a dozen potential candidate genes that may regulate the resistance response. Third, continue to map resistance towards these pathogens as well as others and evaluate candidate genes to develop perfect markers. Fourth, improve management approaches to reduce the impact of these diseases on profitability.

Information And Results
Project Summary

The diseases that negatively impacted soybean during 2018 were unusual, southern stem canker, frogeye leaf spot, sudden death syndrome as well as the usual culprits Phytophthora, Pythium, and SCN. During 2019, Phytophthora was still a problem and root rots in general. With the record setting warm winter, we are predicting residue-borne diseases will be an issue. Thus the first objective is to survey and monitor the pathogens that affect soybean. Second, evaluate genetic changes and fungicide sensitivity in these populations. Host resistance is the most effective tool to manage these diseases. Resistance to these soil borne pathogens was identified as well as more than a dozen potential candidate genes that may regulate the resistance response. Third, continue to map resistance towards these pathogens as well as others and evaluate candidate genes to develop perfect markers. Fourth, improve management approaches to reduce the impact of these diseases on Ohio farmers profitability.

Benefit To Soybean Farmers

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.
