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.
Budgeting With an Irregular Income
If you are a business owner, farmer, rancher, earn based on sales commissions, or are seasonally employed, you may not have consistent income from month to month.
Keeping Your Financial Records Secure
When a family emergency or disaster occurs, having quick access to important financial documents is essential.
Agritourism
When a producer has decided to sell a product directly from the farm, entertainment or tourism-based activities could be incorporated to create larger appeal. Agritourism could add value to the farm visit though education, entertainment, outdoor recreation, dining, relaxation or other avenues, potentially drawing more customers in.

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.
An identification guide to common Rangeland Insect Pests of South Dakota
The insects listed in this guide can be pests of rangeland in South Dakota. The best approach for preventing these pests from reaching damaging populations involves routine scouting.
Lawn Weed Control
Cultural weed control practices must be included in weed management programs to optimize control and inhibit re-infestation. A healthy, dense turf cover is the best overall defense against weed invasion. Some common cultural weed control practices include planting the most adapted turfgrass species for your environment (i.e. shade, full sun, or hot, dry conditions), maintaining a mowing height of 2.5–3.5 inches, watering deeply but less frequently, and proper soil maintenance including fertilization and core aerification.
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.
