Brief Project Summary:

The objectives of this project are to continue to survey field isolates that are responsible for causing soybean sudden death syndrome and root rot in Alabama, and evaluate previously collected field isolates of the Fusarium solani species complex, namely F. falciforme, F. paranaense, and F. solani sensu stricto, and their ability to cause disease on cultivars of soybean. Additionally, fungicide efficacy will be evaluated for members of the isolates in Alabama to determine possible disease management recommendations.

Key Benefactors:
farmers, agronomists, Extension agents

Information And Results
Project Deliverables

Soybean plants in the field showing symptoms of soybean sudden death (SDS) will be removed and FSSC isolates cultured from the hypocotyl tissue. Genetic material of the fungus will be extracted and the genetic background of the fungus determined using well established molecular methods that include DNA sequencing. Pathogenesis of representative isolates will be evaluated in a growth chamber on susceptible soybean cultivars. Additionally, fungicide efficacy will be evaluated for members of the FSSC isolates in Alabama to determine possible disease management recommendations.

Final Project Results

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.
