Brief Project Summary:

Since 2003, soybeans grown in Kentucky have been commonly sprayed with strobilurin-based fungicides, primarily to obtain general "health plant" benefits, but occasionally to control common foliar fungal diseases, such as brown spot and frogeye leaf spot. The first case of strobilurim-resistant frogeye leaf spot was reported in Tennessee during the summer of 2010. In October, resistant frogeye leaf spot was detected in 3 of 13 samples collected from Princeton, Caldwell County, Kentucky.

The Kentucky find could simply represent a significant, but low, incidence of naturally occurring isolates of Cercospora sojina, or spores of strobilurin resistant isolates that may have blown in from...

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.
