Overwintering S.D. Bean Leaf Beetles: 2017 predicted mortality

The overwintering generation of bean leaf beetle adults emerge in the spring and can cause serious defoliation injury to seedling soybean plants. However, the abundance of overwintering bean leaf beetles is negatively affected when the air temperatures get too cold. Therefore, an estimate of the emerging populations can be made based on how cold the winter was.

Want a Premium Price? Weed Control In NON-GMO Soybeans

Many emotions set in on farmers that hear the word “non-GMO”, but it could help them in times like today when prices are low for many farm products in South Dakota.

Improving Protein Content in Wheat

Wheat producers in South Dakota always strive to grow a premium product. Quality in wheat often depends on test weight and protein content.

Scouting Winter Wheat for Mite Pests

Winter wheat planting is underway in South Dakota. After wheat emergence, it is important to scout for brown wheat mite and wheat curl mite populations.

Scouting Winter Wheat for Aphid Pests

Although we cannot predict aphid pressure in winter wheat, there are measures that may be taken to reduce the risk associated with these insects.

Split Application of Nitrogen in Winter Wheat

Adequate N early in the growing season is important to support healthy tillering and to give young plants the best opportunity to survive the sometimes-harsh South Dakota winter

Why the 250 Threshold is Still Appropriate for Soybean Aphids

When gearing up for soybean aphid scouting, it is important to think about the population densities that warrant insecticide management.

Soybean Pests: Bean Leaf Beetles and Bean Pod Mottle Virus

With the number of bean leaf beetle observations in soybean fields during 2016, the need for monitoring soybean for Bean pod mottle virus (BPMV) development increases. Bean pod mottle virus was first identified in South Dakota in 1998, and is recognized as a very economically important disease in soybean due to the potential for it to cause devastating losses to soybean yields.

Soybean Diseases Update

A few soybean fields scouted had between low to moderate levels of brown spot (also known as Septoria leaf spot). Soybean planted into soybean stubble had elevated levels of brown spot.

Yellow Soybeans

Yellow soybean areas within fields are being noticed in some areas of the state. There are six factors which could be causing the soybean plant yellowing: nitrogen (N), potassium (K), or sulfur (S) deficiency, iron deficiency chlorosis (IDC), soybean cyst nematode (SCN), or yellow flash from Roundup application.
