Southern rust was found in a few corn fields scouted last week. This rust is developing very late in the season and therefore its impact on corn yield will be minimal.
As the first frost date approaches, producers often have concerns about the risk of prussic acid poisoning in livestock. Certain forage plants, especially sorghums and related species are associated with an increased risk of death loss because of prussic acid poisoning.
Broadacre spraying of pastures is intended to reduce undesirable plants and increase grasses for livestock. This practice often results in unintended consequences, including damage and reduction of native forbs and reduced profitability. One approach to managing perceived “weedy” plants is incorporating different species of livestock into a grazing operation.
2019 has been a year fraught with challenges for ranchers across South Dakota. Abundant precipitation is usually a blessing, however, wet conditions coupled with a cool spring followed by warmer temperatures has caused another problem across the rangelands of South Dakota: ergot poisoning.
Corn ear rots are one of the last diseases to scout for in the corn growing season, and sometimes they are ignored or forgotten entirely. Ear rots can cause yield loss in the form of grain quality at harvest, but also cause losses during storage.

If the forecast holds true, it looks like it is going to be another year of excessive soil moisture and possible flooding come this spring. The increased level of soil moisture has implications with regards to plant stand establishment as well as root rot and nematode infestations.
Bovine Viral Diarrhea Virus (BVDV) is among the most important pathogens affecting today’s beef and dairy cattle operations. Associated with reproductive, digestive, and respiratory illnesses in cattle, the virus can also create a congenital, persistent infection in calves, greatly aiding the virus’ spread within and between herds.
The South Dakota Pest Management guides are now available for free. The guides offer recommendations for controlling weeds, insects, and diseases in a variety of South Dakota crops.
