Brief Project Summary:

Sudden death syndrome can cause significant soybean yield losses annually in Indiana. The overall goal of this project is to better understand the impact of the early growing environment on SDS development. The research is designed to provide results under controlled conditions within one year, which can be validated or investigated further through future research. Objectives include determining how temperature, moisture, and plant age affect root colonization by Fusarium virguliforme and foliar expression of SDS; and examining the impact of ILeVO on SDS severity under varying temperatures and soil moisture levels.

Key Benefactors:

Final Project Results

Update:
refer to final results

Research conducted under controlled conditions at Purdue University indicated that soil moisture and seed treatment did not affect root disease expression of SDS, but temperature did impact dry matter of root tissue, with temperatures below 20 C having less root dry matter. This research is a first step in understanding how early season environmental conditions impact root infection by the SDS pathogen, which will help us provide unbiased research results to Indiana farmers about under what environmental conditions SDS will be more severe and how fungicide treatment may reduce disease and improve yield.

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.
