Many of the soybean samples that have been submitted to the ISU Plant Disease Clinic show signs of hail injury, due to the severe storms and associated hail damage earlier this summer. Disease scouting in late July and August may reveal more stem diseases than usual in fields that had hail injury because wounds from the hail are ideal entryways for some pathogens. Stem canker is one stem disease to be concerned with after such weather conditions.
