Southern corn rust found in Madison Co. FL yesterday (June 3) just south of the Georgia line. With approaching weather this weekend, I advise growers in Deep South Central and deep Southeast Georgia to consider a fungicide application if their corn is nearing tassel or beyond. Fungicides like Tebuconazole and other single mode of action products are generally “OK” for control of rust, but don’t have as long of a protective window. When you use products with mixed modes of actions, e.g. triazoles + strobilurins, or traizoles + strobilurings + SDHIs, or SDHIs + strobilurins, you increase efficacy, broad spectrum activity and protective windows.
