Southern Corn Rust: Is a Late Fungicide Application Warranted?
Southern rust continues to be a topic of conversation throughout the MS corn production area. Presently, the disease can be observed at low levels in a patchy distribution throughout the Delta. However, there are likely some fields that contain hot spots of the disease. Scouting continues to be necessary in situations where a fungicide application could be beneficial. But, the necessity to apply a fungicide will be dependent on several important variables.
