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.
Fungicide Resistance: Risk and Management
What is fungicide resistance?
Fungicide resistance can be defined as when a pathogen population is no longer sensitive or has reduced sensitivity to the fungicide that used to control the same pathogen.
Communication: Importance of Social Support in Agriculture

Are you ready for winter? ¿Està listo para el invierno?
The first winter experience can be a challenge if you don’t know what is ahead, except for that there will be snow and cold. Some simple tips will help you survive the snow, ice and low temperatures.
Feeding at the Right Price
Managing feedstuffs efficiently becomes more important during drought conditions or low revenue years.
Early Weaning as a Drought Management Strategy
Successfully managing drought conditions requires balancing the amount of forage demanded by grazing livestock with the amount produced.
Economic Considerations for Early Weaning
There is an excellent reason why ranchers use early weaning as a drought management tool: Weaning calves early reduces the amount of feed required to maintain the cow.
Field Pea Variety Trial Results
In 2023, field pea trials were planted at different locations in South Dakota.
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.
Fire Blight
Fire blight is a disease that can infect apples, pears, and certain ornamental species including crabapples, cotoneaster, and mountain ash. Occasionally it may also appear on cherries, plums, Juneberry (also called Serviceberry or Saskatoon), and raspberry. This disease, caused by the bacteria Erwinia amylovora, can damage blossoms, fruit, leaves, shoots, and branches. If it is not controlled, fire blight may kill the entire tree or shrub. Infected tissue cannot be cured, but will need to be removed from the tree to prevent further spread.
