Looking for Foodborne Germs and Their Resistance to Antibiotics
How often do the meat products we buy in the store contain germs that might cause illness in people? Can we learn anything about antibiotic resistance with that information? Those are just two of the questions that SDSU is examining as part of their work with the National Antimicrobial Resistance Monitoring System (NARMS).
Reviewing Humane Euthanasia Protocols
Unresolvable health problems and injuries occur in pigs in every swine operation and having a plan in place to humanely deal with these issues is critical. This includes having a written protocol for timely euthanasia.
Zebra Mussels Impacting Missouri River Reservoir System

Northern Corn Leaf Blight Developing in Corn
Northern corn leaf blight was found in a few corn fields scouted recently. The disease was found at very low severity, except occasionally when an individual plant was found with several lesions on one leaf.
Green Cloverworms Causing Defoliation in Soybean
Populations of green cloverworm, a caterpillar pest of soybean, have been increasing over the last couple of weeks in South Dakota. Although green cloverworm caterpillars feed on soybean leaves, defoliation rarely results in economic loss. However, reports of increasing populations of green cloverworm and increasing amounts of defoliation suggests that scouting for this insect pest is warranted.
Soybean Gall Midge Showing Up in More Counties
As the season continues, so is our soybean gall midge scouting efforts. For much of South Dakota, the soybean that are infested with soybean gall midge are asymptomatic. That is, they show limited signs of infestation, but we can still find the larvae of the soybean gall midge in the stems.
Watch for Red Sunflower Seed Weevils
In South Dakota, sunflower flowering is well underway. That means it is time to start scouting fields for red sunflower seed weevils. During the last two years, red sunflower seed weevil populations have been higher than normal with areas that exceeded the thresholds by as many as 300-500 adults per sunflower head.
Differentiating Two Species of Sunflower Seed Weevils
While scouting sunflower, there are two types of seed weevils that you may encounter. They are the red sunflower seed weevil and the gray sunflower seed weevil. It is possible to observe both of these species on a single sunflower head.
Cow Mineral Nutrition: Macro Minerals and Their Importance
Mineral nutrition is vital to overall cow performance. There are seven macro minerals that need to be analyzed and balanced within a cow’s diet. These are calcium (Ca), phosphorus (P), magnesium (Mg), sulfur (S), sodium (Na), chlorine (Cl) and potassium (K).
