Bacterial Leaf Streak of Corn: A New Corn Disease in South Dakota

Bacterial leaf streak, caused by Xanthomonas vasicola pv. vasculorum (Xvv), is a recently discovered disease of corn in South Dakota. The disease was first identified in Nebraska in 2016 but now has been found in the majority of the Corn Belt states. Under favorable weather conditions bacterial leaf streak can develop to reach yield reducing levels. Like any other bacterial disease, once symptoms develop there is little that can be done to control it in the field. However, it is important to correctly diagnose this as a bacterial disease because it can be confused with gray leaf spot which is a fungal disease.

Pre-weaning Pneumonia in South Dakota Beef Herd: A Persistent Problem, Suddenly Gone

This case report describes a southeastern South Dakota cow-calf herd’s experiences with pre-weaning pneumonia. Unlike many beef herds that experience pneumonia in calves on pasture, this herd’s problems were consistent year after year: widespread calf illness was documented in each of 6 consecutive summers. Anecdotally at least, the occurrence of pre-weaning pneumonia in beef herds is more likely to be sporadic and unpredictable from year to year. This herd’s persistent problems were followed by a year in which, after a change in calf vaccination protocol (informed by herd diagnostics), very little pre-weaning pneumonia was observed.
