Bayer Advanced 12 Month Tree & Shrub Insect Control Landscape is not labeled for Southern Blight. Southern blight is extremely difficult to manage because the fungus has a wide host range (more than 500 plant species in 100 plant families). We would recommend contacting the local cooperative extension office for a fungicide and treatment program recommendation that is effective in your region.
