Grassland Management Do’s and Don’ts

This article is intended to address the variety of questions we receive related to establishing, re-establishing and maintaining grass-based plantings for grazing, hay, wildlife and recreation.

Partnerships Are Keys To Preventing Endangered Species Impacts

South Dakota’s farmers and ranchers have significant influence on the management of our state’s natural resources, especially grasslands and the species that inhabit them. These species remind us of the importance of natural resources management for the greater good.

Range Roundup: Virtual Fencing Project Takes Place at the Cottonwood Field Station

Virtual fencing (borders without physical barriers) has started making waves in the cattle industry, and it can be used to implement precision grazing management. Our team is researching its use and utility at the SDSU Cottonwood Field Station starting this summer.

July Drought Hours to Address Livestock Nutrition, Crop Quality Concerns

July 15, 2021

More South Dakota acres are now in an extreme drought condition as lack of moisture and high temperatures continue to impact much of the state.

Blister Beetles Showing up in Alfalfa Fields

Blister beetles are now active in South Dakota. Although the larvae of blister beetles can be beneficial by feeding on grasshopper eggs, the adults cause issues when large populations are present in alfalfa at the time of harvest.

Keep Scouting for Alfalfa Weevils

This week we received a report and picture confirmation of early-instar alfalfa weevil larvae in an alfalfa field. Although most alfalfa fields were treated for alfalfa weevils before the first cutting, those fields still need to be scouted.

Cowpea Aphids Infesting Alfalfa

Typically, we worry about pea aphids in alfalfa. However, we noticed that cowpea aphids were present on alfalfa this week. If left unmanaged, cowpea aphids can stunt alfalfa, reduce yields and even kill the plants during severe infestations.

Spider Mites Reported in South Dakota Crops

With drought conditions continuing in South Dakota, it isn’t surprising that two-spotted spider mite infestations are being reported throughout the state. With hot temperatures in the forecast and limited chances for precipitation, we can expect spider mite populations to thrive in infested fields.

Drought Conditions May Increase Soybean Cyst Nematode Population in Soil

Moisture stress coupled with above-normal temperatures have been linked with increased soybean cyst nematode populations in the soil. In order to keep populations in the soil below the yield-reducing levels, there are a few management practices which can be used.
