Gall Midge Larvae in Soybean Stems

Gall midge larvae were observed recently in soybean stems from a field in South Dakota. These insects were found under the epidermis of the stem that was slightly above the soil line.

Wheat Streak Mosaic Virus Management: Plan ahead before planting this fall

Have you had a history of moderate wheat streak mosaic disease in your field? Do you plan on planting wheat into wheat stubble or wheat fallow? Have your neighbors had wheat streak mosaic disease outbreaks in the recent past? If you answered yes to any of these questions, you need to incorporate wheat streak mosaic control principles into your management plan before planting winter wheat this fall.

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.

Production and Utilization of Field Peas, Lentils and Chickpeas in South Dakota

Dry field peas and lentils are high in protein and fiber, have a low glycemic index, are easy to prepare, store well, and are low in cost. Even better they can be produced economically and sustainably in South Dakota as part of diverse no-till crop production systems.

Soybean Drying and Storage

Why dry crop seeds artificially when they can be naturally dried in the field? Two major reasons are: i) allows harvesting when the crop is ripe and mature, and ii) proper storage that preserves seed quality.

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.

Glyphosate Resistance in Soybeans

Many weeds have developed glyphosate resistance in the past few years. Many producers who use Roundup Ready soybeans have a temptation to rely on glyphosate products to control post-emergent weeds, causing them to potentially become resistant to the chemical. If producers are unable to gain control over the weed, then weed competition will cause a significant yield loss.

The Small Grains Disease Forecasting System Could Save Producers Money

The South Dakota State University Small Grains Plant Pathology program has partnered with the Small Grains Plant Pathology program at North Dakota State University to deploy a small grains disease forecasting system for South Dakota. The system uses weather variables including rainfall, temperature, and relative humidity to predict the likelihood of disease development. This new tool has the potential to save growers money by helping them avoid unnecessary fungicide applications, or knowing when to apply a rescue fungicide treatment.

The Difficulty in Winter Wheat Stand Assessments

From freak snow storms to sub-zero temperatures and on to a recent lack of moisture and a cool spring, the climate in South Dakota has left many winter wheat growers and agronomists wondering about the health of their stands.

Crop Rotation in Farm Management 

Crop rotation has long been considered an important farm practice. In 2013 producers had to stray from their well thought out crop rotations when the winter wheat crop in South Dakota failed.
