Expert Response
We can't determine whether southern blight is present by viewing the photos.
Unless the blight's presence has been confirmed by laboratory analysis, please send samples of affected plants to the University of Minnesota Plant Disease Clinic.

If samples prove to be positive for blight, ask clinic staff to explain how to deal with it.
