Brief Project Summary:

Soybean rust and other foliar diseases, such as Aerial web blight, target spot, frogeye leafspot and Cercospora leaf blight have caused significant damage to soybeans in recent years, when weather conditions favored development. Since 2011, frogeye leafspot has been found to be resistant to strobilurin fungicides, showing the need to continue testing new fungicides. This project evaluates how best to use different timings and combinations of products to control foliar diseases that can affect soybean yield and cause quality losses. It also monitors for disease resistance to fungicides.

Information And Results
Project Deliverables

Fungicide tank-mix and sequential trials will be continued at Alabama Agricultural Research Stations. Due to the most consistent annual rust infections, the Gulf Coast REC will be the primary location for ASR investigations. Other locations in central and north AL will be included to provide information on soybean rust and other important diseases. Northern locations will utilize varieties relatively susceptible to frogeye leafspot, for fungicide resistance monitoring. Trials will consist of combinations of fungicide applications at early bloom/pod set, followed by one or more applications of the same or different fungicides at 14 to 21-day intervals, depending on the trial. As new products and classes become available, including bio-based, they will be included in these trials.

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.
