Brief Project Summary:

Researchers will survey farmers to see how they manage stem diseases and pests. The survey has not been conducted in nearly 20 years. The team will collect soybean plant samples themselves as well as from farmers and will use molecular techniques to confirm diseases. They are conducting an insect pest assessment with Illinois entomologists as well. A database will be developed on disease and pest ranges across the state and provide feedback to farmers as well.

Key Benefactors:
farmers, entomologists, agronomists, pathologists+G6

Information And Results
Project Deliverables

The proposed research will improve our understanding of the perceived and actual impact of stem diseases and insect pests on soybean production in IL. It will also help identify new and emerging pathogens and pests that could affect soybean production in IL. The generated information would be crucial to direct and prioritize future research targeting the management of these pathogens and pests in IL.

Proposed outcomes - The proposed research will improve our understanding of stem diseases' perceived and actual impact on soybean production in Illinois. It will also help identify the major and most impactful pathogens that cause these diseases in IL. More specifically, this proposed research will:

1. Monitor the incidence and spread of red crown rot in Illinois. This will help elucidate the importance of this pathogen in Illinois and whether this disease is expanding in the state.

Determine what fungal species cause stem canker in Illinois. This information is essential to manage the disease and use adequate management tools, including developing and deploying adequate sources of resistance to the pathogen.
Assess the incidence and the potential yield loss caused by Dectes stem borer in soybean production fields in Illinois.
Assess and survey Illinois soybean fields for the soybean gall midge with the purpose of early detection of this new soybean pest.
Result in building a collection of pathogens associated with stem diseases. Such collections are an invaluable resource for researchers to study the biology of these pathogens. They also permit assessing host resistance under controlled conditions.
The information generated from the proposed research will be crucial to direct and prioritize future research targeting the management of the most destructive soybean stem-diseases-causing pathogens in Illinois.

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.
