One of the primary challenges for livestock producers in the coming months could very well be feedstuff cost and availability due to the fact that the corn planted acreage and crop progress are both well behind normal benchmarks. One opportunity that might help cattle feeders proactively secure feed supplies would be storing wet or modified distiller’s grains now to be fed at a later date.

Aphid populations in winter wheat continue to be observed in South Dakota. The major questions now are whether or not aphid populations are at economic threshold and if spraying is really necessary.
Winter wheat is past the need for an in-season fungicide application. However, many spring wheat fields are yet to flower, making them prone to disease development. A few diseases, including leaf rust, stripe rust, and Fusarium head blight have developed in winter wheat. This implies that there is enough inoculum available for these diseases to develop in spring wheat; especially East River, where rainfall has been frequent.
While scouting canola this week, I came across a field that had plants along the edge that looked like they were suffering from drought stress, but given the recent rain I doubted that to be the case. Closer inspection of the stressed plants indicated that they were covered in false chinch bugs. Although false chinch bugs are not normally an issue in canola, very large populations do have the potential to reduce yield.
The Big Sioux River Flood Information System is the result of a combined effort between the SD Department of Environment and Natural Resources, local governments, and private industry, to create a product that can be used to predict the impact of flood events in the Big Sioux River Basin.
As many Midwest producers look to cover crops to build soil health and provide supplemental forage after a soggy spring, many questions are arising regarding management decisions, specifically, species selection and planting timing.
As a challenging 2019 row crop planting season wraps up in South Dakota, many producers are looking to plant cover crops on unplanted acres. One popular cool-season grass cover crop is oats. Most oats in South Dakota are grown as certified varieties, and it is important to be aware of the legal ramifications behind purchasing oat seed for use as a cover crop.
Winter wheat fields scouted last week show an increase in fungal leaf diseases and bacterial leaf streak. Among the fungal diseases, the most common leaf diseases are tan spot, Stagonospora leaf blotch, and stripe rust. The risk for Fusarium head blight has also started to increase in a number of areas in the state.
Oats scouted in a few fields in the Eastern and South Central parts of the state were found with bacterial blight developing on the lower leaves. Plants infected have leaves with water-soaked brown longitudinal lesions in the top-half of the leaf. Severe symptoms can lead to premature leaf death.
Last year, the soybean gall midge caused a lot of issues in soybean, including lodging and up to 50% yield loss. In an effort to determine when soybean gall midge adults are emerging in 2019, a network of emergence traps has been established in South Dakota, Nebraska, Iowa and Minnesota. So far, emergence of the adult soybean gall midge have been reported from Iowa, Nebraska and Minnesota.
