Brief Project Summary:

The research project will assess the gains in Sclerotinia stem rot (SSR) control, soybean yield, and soybean quality that ND producers can obtain by integrating the use of partially resistant soybean varieties with fungicides. Susceptible and partially resistant soybean varieties from two maturity groups will be evaluated under three fungicide treatments and a non-treated control. The trial will be established under the NDSU Carrington Research Center's misting system, and it will be inoculated to ensure consistent disease pressure throughout the trial. Information generated by this project will lead to improved disease control, reduced economic losses, and increased profitability of soybean...

Information And Results
Final Project Results

Partial host resistance to Sclerotinia in soybeans is conferred primarily by plant architecture traits that promote increased air movement within the canopy. Row spacing may influence the expression of those traits. To address this concern, in 2013, field trials have expanded to evaluate the use of fungicides and partially resistant varieties under 7-inch, 14-inch, 21-inch, and 28-inch rows.

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.
