Frogeye leaf spot (FLS) is a mid-to-late season foliar leaf spot disease, caused by the fungus Cercospora sojina. It can be found in almost every soybean field in Tennessee, but it causes the most damage on highly susceptible varieties. This disease may be more severe in low-lying fields, creeks and river bottoms. In years when conditions are favorable, FLS can prematurely defoliate soybean plants, causing up to 50 percent yield loss on susceptible varieties. In the last four years, FLS caused a significant 7.8-8.0 percent loss to the Tennessee soybean crop. Due to extreme dry weather FLS only caused a 2 per cent decrease in yield this past season. There are over a hundred different...
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.
