Noxious Weed Control in Pasture and Range
Noxious weed control in pastures is becoming more of a challenge. Most ground commercial spray businesses are no longer spraying pastures. If they are, there may be restrictions on the time they will spray, what products they will spray, or they may only spray if they also have all of the rest of your spraying business.

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.
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.
