Investigation of Soybean Seed Treatment and Inoculant in Southeastern SD, 2018

Soybean seed treatment products are widely utilized by many farmers in southeastern South Dakota and the surrounding area. These products often consist of an insecticide/fungicide combination, and/or inoculant that is mixed and placed on the seed as a pre-treatment before the grower plants the crop.

Late Plant Crop Insurance Dates

Crop insurance late plant dates are fast approaching for planting small grains in South Dakota. Late plant dates for corn, soybean, and sunflower are nearing as well. Producers will want to work with their crop insurance agent to explore planting options and reporting of prevent plant areas.

Test Your Soil for the Soybean Cyst Nematode (SCN) This Spring

The soybean cyst nematode (SCN) is a major soybean pathogen that causes significant yield loss. Fields that were not tested for SCN last year can still be sampled this spring to determine the presence of SCN or SCN population changes if testing was done in the past.

Planting Considerations and Resources for 2019

As May approaches, many farmers are preparing for row crop planting. In areas where flood waters have receded and soils are dry enough to begin field operations, farmers will likely be out in full swing soon.

2019 South Dakota Grasshopper Forecast

The USDA Animal Plant Health Inspection Service conducts an annual survey to monitor grasshopper populations in Western South Dakota. In 2018, SDSU conducted a survey to monitor populations in Eastern South Dakota. These previous-year surveys can be used as a prediction tool for where grasshoppers may be an issue during the upcoming season.

April 22, 2019

As the outdoor temperature rises this spring, stored grains are warming as well. Due to a difficult and wet harvest last fall, many producers in the region chose to store grains much wetter than typical. As a result, special care needs to be taken for these grains as the air temperature rises this spring, explained Sara Bauder, SDSU Extension Agronomy Field Specialist.
