Cover Crops 2019 - What to Plant When

July 10, 2019

As many Midwest producers look to cover crops to build soil health and/or provide supplemental forage after a soggy spring, many questions are arising regarding management decisions, specifically species selection and planting timing.

Storing Wet and Modified Distillers Grains

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.

Continue Scouting Wheat for Aphid Populations

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.

Diseases in Winter Wheat Imply High Inoculum for Spring Wheat

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.

Monitor Canola Fields for False Chinch Bug Activity

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.

Big Sioux River Flood Information System Sees Heavy Use During Spring 2019

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.

Buying or Selling Oats for a Cover Crop? Be Sure to Follow the Rules

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 Disease Update: Leaf Diseases and FHB on the Increase

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.
